Summary

A denial of service security issue exists in the affected product. The security issue stems from a fault occurring when a crafted CIP message is sent. Devices with less memory are more likely to be affected. This can result in a major nonrecoverable fault (MNRF). A program download is required to recover.

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.
