CVE-2022-2465

Code execution via unrestricted object deserialization

Published Aug 25, 2022 · Updated Apr 16, 2025

Deserialization in Rockwell Automation ISaGRAF Workbench 6.0 through 6.6.9 allows attackers to execute code via a crafted serialized object. The deserialization path accepts attacker-controlled objects without restricting the object types it can instantiate. Execution requires a local user to open the malicious object, and resulting code runs in the Workbench process context.
