Summary

When performing an online tag generation to devices which communicate using the ControlLogix protocol, a machine-in-the-middle, or a device that is not configured correctly, could deliver a response leading to unrestricted or unregulated resource allocation. This could cause a denial-of-service condition and crash the Kepware application. By default, these functions are turned off, yet they remain accessible for users who recognize and require their advantages.

Fencer Intel 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.
