CVE-2022-30267 is an operational technology firmware authenticity weakness affecting a Distributed Control System. The device does not cryptographically sign firmware images and relies only on insecure checksum-based integrity checks during firmware validation. As a result, the firmware update mechanism does not adequately verify the authenticity and trusted origin of firmware before accepting it. This creates a condition in which modified or malicious firmware can be treated as valid if it satisfies the weak checksum mechanism, undermining the trust model for firmware distribution and installation.
