Cisco NX-OS Software NX-API Privilege Escalation Vulnerability

A vulnerability in the NX-API management application programming interface (API) in devices running, or based on, Cisco NX-OS Software could allow an authenticated, remote attacker to execute commands with elevated privileges.

The vulnerability is due to a failure to properly validate certain parameters included within an NX-API request. An attacker that can successfully authenticate to the NX-API could submit a request designed to bypass NX-OS role assignment. A successful exploit could allow the attacker to execute commands with elevated privileges.

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