RuggedCom RuggedOS Default 'factory' Account Backdoor

Critical Nessus Plugin ID 58991


The remote network device has a hard-coded user account with predictable credentials.


The remote device is running RuggedCom RuggedOS (ROS). Using the user name 'factory' and a password derived from the MAC address of the device (which is present in the telnet login banner), Nessus was able to successfully log into the device via a built-in backdoor account.


Upgrade to the latest RuggedOS firmware version per the vendor's advisory.
