What is CVE-2024-45368?
CVE-2024-45368 is a high-severity authentication bypass vulnerability in AutomationDirect DirectLogic H2-DM1E, published on 13 Sep 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The H2-DM1E PLC's authentication protocol appears to utilize either a custom encoding scheme or a challenge-response protocol. However, there's an observed anomaly in the H2-DM1E PLC's protocol execution, namely its acceptance of multiple distinct packets as valid authentication responses. This behavior deviates from standard security practices where a single, specific response or encoding pattern is expected for successful authentication.
