CVE-2022-30267 affects a Distributed Control System that does not authenticate firmware images with cryptographic signatures. Firmware integrity is checked only through insecure checksum mechanisms, which do not establish image origin or provide robust protection against modification. As a result, the system can accept firmware whose authenticity has not been adequately verified.
