Detail

A vulnerability in the CLI parser of Cisco NX-OS Software could allow an authenticated, local attacker to perform a command-injection attack on an affected device.

The vulnerability is due to insufficient input validation of command arguments. An attacker could exploit this vulnerability by injecting malicious command arguments into a vulnerable CLI command. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the affected device.

Note: This vulnerability requires that any feature license is uploaded to the device. The vulnerability does not require that the license be used.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
