Cisco IOS XE Software CLI Command Injection Multiple Vulnerabilities (cisco-sa-20180328-cmdinj)

high Nessus Plugin ID 132052

Language:

Synopsis

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

Description

According to its self-reported version, Cisco IOS XE Software is affected by multiple vulnerabilities in the CLI parser because the affected software does not sufficiently sanitize command arguments before passing commands to the Linux shell for execution. An authenticated, local attacker can exploit this, by submitting a malicious CLI command, in order to gain access to the underlying Linux shell of an affected device and execute commands with root privileges on the device.

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.

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID(s) CSCuz03145, CSCuz56419, CSCva31971, and CSCvb09542.
