Vulnerable Application

This module retrieves a browser's network interface IP addresses using WebRTC. However, after visiting the HTTP server, the browser can disclose a private IP address in a STUN request.

Verification Steps

Start msfconsole
use auxiliary/gather/browser_lanipleak

Visit server URL in any browser which has WebRTC enabled
