How the Exploit Works
The vulnerability lies in the Built-In-Self-Test (BIST) mode of the affected RUGGEDCOM ROX devices. The devices do not adequately limit access in this mode, enabling an attacker with physical access to the serial interface to bypass the authentication process. This bypass allows the attacker to gain access to a root shell on the device, resulting in unauthorized system access and potential system compromise.
Conceptual Example Code
Below is a
conceptual
example of how an attacker might exploit this vulnerability:
# Attacker gains physical access to serial interface
connect to serial interface
# Attacker enters BIST mode
enter BIST mode
# Bypass authentication, gain root access
bypass authentication, get root shellPlease note that this is a simplified representation of the potential exploit and does not represent real code. It is provided for understanding purposes only.
