Vulnerability Description

A vulnerability in the role-based access-checking mechanisms of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on an affected device. The vulnerability exists because the affected software lacks proper input and validation checks for certain file systems.
