Siemens Security Snafu: Mendix Runtime Race Condition Runs Wild!
Siemens’ Mendix Runtime is facing a race condition that could let remote attackers bypass account lockout measures. While CISA is stepping back from updating advisories, Siemens suggests some workarounds. Remember, if your runtime version is outdated, it’s time to update! Don’t let your software run the race without proper synchronization!

Hot Take:
Looks like Siemens is playing a game of “Tag, you’re IT!” with hackers, leaving us to fend for ourselves with a Mendix Runtime vulnerability. Time to sharpen those cybersecurity tools, folks, because CISA’s now saying, “Sorry, you’re on your own!”
Key Points:
- CISA will no longer update ICS advisories for Siemens product vulnerabilities beyond the initial advisory.
- The vulnerability in question is a race condition in Mendix Runtime that could let unauthenticated attackers circumvent account lockouts.
- Siemens advises updating to the latest Mendix Runtime versions or using alternative authentication methods.
- Mitigation strategies include network isolation and using VPNs for remote access.
- No public exploitation of this vulnerability has been reported yet.
