MEDIUM 4.1EPSS 0.25%

Does this matter?

Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.

Description

A user with vpuser credentials that opens an SSH connection to the device, gets a restricted shell rbash that allows only a small list of allowed commands. This vulnerability enables the user to get a full-featured Linux shell, bypassing the rbash restrictions.
