      "value": "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."

Sin embargo, se observa una anomal\u00eda en la ejecuci\u00f3n del protocolo del PLC H2-DM1E, a saber, la aceptaci\u00f3n de m\u00faltiples paquetes distintos como respuestas de autenticaci\u00f3n v\u00e1lidas. Este comportamiento se desv\u00eda de las pr\u00e1cticas de seguridad est\u00e1ndar, en las que se espera una \u00fanica respuesta espec\u00edfica o un patr\u00f3n de codificaci\u00f3n para una autenticaci\u00f3n exitosa."
