"A vulnerability in the CLI of Cisco FXOS Software could allow an authenticated, local attacker to inject 
arbitrary commands that are executed with root privileges. The attacker would need to have Administrator 
privileges on the device. This vulnerability is due to insufficient input validation of commands 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 commands 
on the underlying operating system with root privileges.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
