Kimiya, working with Trend Micro Zero Day Initiative, reported these vulnerabilities to CISA.
VISAM recommends users update to VBASE 11.7.5 or later. The update can be performed via the VBASE Editor update dialog on machines with secure access to the internet. Users of machines without internet access must manually update by submitting a request form to receive a download link.
For more information, users should contact VISAM using the information provided on their contact page (German language).
CISA recommends users take the following measures to protect themselves from social engineering attacks:
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage at cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely. These vulnerabilities have low attack complexity.
