Cisco UCS Manager Software Command Injection Vulnerability

A vulnerability in the CLI and web-based management interface of Cisco UCS Manager Software could allow an authenticated, remote attacker with valid administrative privileges to execute arbitrary commands on the underlying operating system of an affected device.    This vulnerability is due to insufficient input validation of command arguments that are supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system of an affected device with root-level privileges.
