Summary

A security issue exists within 1769 CompactLogix controllers due to the missing validation of sequence numbers and source IP addresses in the CIP protocol. This allows attacker to abuse the exposed Connection ID’s visible on the web interface to perform denial-of-service attacks, resulting in a minor fault.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
