Description

A vulnerability in the CLI of Cisco IOS XR Software could allow an authenticated, local attacker to execute arbitrary commands as root on the underlying operating system of an affected device.

A successful exploit could allow the attacker to elevate privileges to root and execute arbitrary commands.
