Cisco IOS XR Software (affected versions not specified)
Description:
A vulnerability in the CLI of Cisco IOS XR Software could allow an authenticated, local attacker to obtain read/write file system access on the underlying operating system of an affected device. This vulnerability is due to insufficient validation of user arguments that are passed to specific CLI commands.

Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
