IP leak affecting VPN providers with port forwarding

Perfect Privacy, 26. November 2015

 

Vulnerability “Port Fail” reveals real IP address

We have discovered a vulnerability in a number of providers that allows an attacker to expose the real IP address of a victim. “Port Fail” affects VPN providers that offer port forwarding and have no protection against this specific attack. Perfect Privacy users are protected from this attack.

 

This IP leak affects all users: The victim does not need to use port forwarding, only the attacker has to set it up.

 

We have tested this with nine prominent VPN providers that offer port forwarding. Five of those were vulnerable to the attack and have been notified in advance so they could fix this issue before publication. However, other VPN providers may be vulnerable to this attack as we could not possibly test all existing VPN providers.
