Rockwell Automation Controllers Vulnerability: Major Nonrecoverable Fault Alert!
Rockwell Automation’s controllers, including ControlLogix and CompactLogix, have a vulnerability causing major faults when abnormal packets hit the mDNS port. This flaw compromises device availability, scoring an 8.3 on CVSS v4. Mitigations include software updates and network security measures. No public exploits reported yet.
Hot Take:
Rockwell Automation’s controllers are having an identity crisis. Apparently, they think they’re on the fritz when they’re just getting a weird packet in the mail. Time to give those devices a little therapy—or at least a software update.
Key Points:
- CVSS v4 score of 8.3—serious but not apocalyptic.
- Vulnerability affects ControlLogix, GuardLogix, and CompactLogix controllers.
- Always-Incorrect Control Flow Implementation sounds like a bad day at the office.
