insufficient validation of arguments passed to a specific CLI command. An authenticated, local attacker can exploit
these vulnerabilities by including malicious input as the argument of an affected command in order to execute arbitrary
commands on the underlying Linux operating system with root privileges.

Please see the included Cisco BID and Cisco Security Advisory for more information.
