Cisco IOS XR 6.0.1.x and 6.0.2.x < 6.0.2.7 / 6.1.x < 6.1.1.17 Command Input Handling Privilege Escalation

high Nessus Plugin ID 92948

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of Cisco IOS XR running on the remote device is 6.0.1.x or 6.0.2.x prior to 6.0.2.7, or 6.1.x prior to 6.1.1.17. It is, therefore, affected by a privilege escalation vulnerability in the command-line utility due to improper validation of user-supplied input. A local attacker can exploit this, via crafted input to a command within a specific container, to execute arbitrary commands with root privileges.

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCuz62721.
