Name of the Vulnerable Software and Affected Versions Micca KE700 (affected versions not specified)

Description The system has flawed resynchronization logic, making it susceptible to replay attacks. An attacker can exploit this by sending two previously captured codes in a specific sequence, forcing the system to accept stale rolling codes and execute a command. Successful exploitation allows the attacker to clone the alarm key, granting unauthorized access to the vehicle, enabling them to lock or unlock the doors remotely.
