Service interruption via invalid CmpApp address read
Published Aug 3, 2023 · Updated Oct 11, 2024
Improper input validation in CmpApp in affected CODESYS products allows remote authenticated users to interrupt controller service. CmpApp processes crafted CODESYS-protocol requests with inconsistent content and reads internally from an invalid address. Successful login is required, and the invalid-address read can interrupt the affected control or simulation runtime without disclosed data access or modification.
