Synopsis
The remote device is missing a vendor-supplied security patchDescription
According to its self-reported version, Cisco IOS XE Software is affected by a vulnerability in the CLI parser due to the affected software improperly sanitizing command arguments to prevent modifications to the underlying Linux file system on a device. An authenticated, local attacker who has privileged EXEC mode (privilege level 15) access can exploit this by executing CLI commands that contain crafted arguments in order to gain access to the underlying Linux shell of the affected device and execute arbitrary commands with root privileges.Please see the included Cisco BIDs and Cisco Security Advisory for more information.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCuw45594.See Also
