CVE-2022-2474

Unauthorized macro writes via unauthenticated Ethernet commands

Published Oct 28, 2022 · Updated Apr 16, 2025

Missing authentication in Haas Control 100.20.000.1110 allows remote attackers on the same network segment to write unauthorized macros. The Ethernet Q Commands service accepts macro-write commands without authenticating the sender before modifying controller program data. Access requires network reachability to the controller, and successful use changes machine-control macros without authorization.
