CVE-2024-45368

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.

Summary		(es) El protocolo de autenticación del PLC H2-DM1E parece utilizar un esquema de codificación personalizado o un protocolo de desafío-respuesta. Sin embargo, se observa una anomalía en la ejecución del protocolo del PLC H2-DM1E, a saber, la aceptación de múltiples paquetes distintos como respuestas de autenticación válidas. Este comportamiento se desvía de las prácticas de seguridad estándar, en las que se espera una única respuesta específica o un patrón de codificación para una autenticación exitosa.
