New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 6.7


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.
