Description

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).

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
