ICS Advisory: Siemens SINEC INS

Summary

As of January 10, 2023, CISA will no longer be updating ICS security advisories for Siemens product vulnerabilities beyond the initial advisory. The document provides information on vulnerabilities in Siemens' SINEC INS product, including improper certificate validation, input validation, and OS command injection. Successful exploitation of these vulnerabilities could allow an attacker to create a denial-of-service condition, intercept credentials, or escalate privileges on the affected device. Siemens has released software updates to mitigate these vulnerabilities, and CISA recommends defensive measures such as minimizing network exposure, using firewalls, and implementing VPNs.
