"According to its self-reported version, Cisco Adaptive Security Appliance is affected by a vulnerability in the CLI
that allows an authenticated, local attacker to inject arbitrary commands that are executed with root privileges. The
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.");
