Nat Slipstreaming v2.0 allows an attacker to remotely access any TCP/UDP service

This article details NAT Slipstreaming v2.0, a critical vulnerability that allows attackers to bypass a victim's NAT/firewall and remotely access any TCP/UDP service on their internal network. The attack is triggered simply by the victim visiting a malicious website and exploits Application Level Gateway (ALG) mechanisms in routers and firewalls. It builds upon previous work by Samy Kamkar and includes new techniques for local IP address discovery.
