"According to its self-reported version, the Cisco IOS XE Software is affected by a vulnerability that allows an
authenticated, local attacker to inject arbitrary commands that are executed with elevated privileges. The
vulnerability is due to insufficient input validation of commands supplied by the user. An attacker can exploit this
vulnerability by authenticating to a device and submitting specially crafted input to the affected commands. An exploit
allows the attacker to gain root privileges on the affected device.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.
