EPSS · scored 2026-10-23

RuggedCom Rugged Operating System (ROS) 3.10.x and earlier has a factory account with a password derived from the MAC Address field in the banner, which makes it easier for remote attackers to obtain access by performing a calculation on this address value, and then establishing a (1) TELNET, (2) remote shell (aka rsh), or (3) serial-console session.

remediations

Vendor fix, mitigation, or workaround guidance, as published by each source.

No vendor fix yet; a mitigation is available.

MitigationROScisa_csaf_ot
Note: These new versions of the ROS firmware remove the factory account and the associated security vulnerability. Customers using these new versions of the firmware should take special care not to lose the user defined password to a device’s administrative account as recovering from a lost administrative password will now require physical access to the device to reset the passwords.
