Recommended Practices
NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.NCCIC 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 on the ICS-CERT website in the Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.

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

"data": "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",
