This attack requires sending two previously captured codes in a specific sequence. As a result, the system can be forced to accept previously used (stale) rolling codes and execute a command. Successful exploitation allows an attacker to clone the alarm key. This grants the attacker unauthorized access to the vehicle to unlock or lock the doors."}, {"lang": "es", "value": "El sistema Micca KE700 contiene l\u00f3gica de resincronizaci\u00f3n defectuosa y es vulnerable a ataques de repetici\u00f3n.
