Critical Manufacturing, Energy, Water and Wastewater Systems
Countries/areas deployed
East Asia, United States, Europe
Company headquarters location
Taiwan
Recommended Practices
ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should: Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet; Locate control system networks and remote devices behind firewalls, and isolate them from the business network; When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
Recommended Practices
ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Recommended Practices
ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Recommended Practices
Additional mitigation guidance and recommended practices are publicly available in the ICS -CERT Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site.
Recommended Practices
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.
Exploitability
No known public exploits specifically target these vulnerabilities.

Risk evaluation
ATTENTION: Remotely exploitable/low skill level to exploit.
Critical infrastructure sectors
Critical Manufacturing, Energy, Water and Wastewater Systems
Countries/areas deployed
East Asia, United States, Europe
Company headquarters location
Taiwan
Recommended Practices
ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should: Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet; Locate control system networks and remote devices behind firewalls, and isolate them from the business network; When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
Recommended Practices
ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Recommended Practices
ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Recommended Practices
Additional mitigation guidance and recommended practices are publicly available in the ICS -CERT Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site.
Recommended Practices
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.
Exploitability
No known public exploits specifically target these vulnerabilities.

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

"data": "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",
