"According to its self-reported version number, the version of Cisco
Prime Security Manager installed on the remote host is affected by a
command injection vulnerability in GNU Bash known as Shellshock. The
vulnerability is due to the processing of trailing strings after
function definitions in the values of environment variables. This
allows a remote attacker to execute arbitrary code via environment
variable manipulation depending on the configuration of the system.");
