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
