Teredo Source Routing Vulnerability in Networking Solutions

CVE-2006-6263

Summary

The Teredo protocol features a vulnerability wherein clients with source routing enabled can unwittingly expose networks to remote exploitation. Under specific conditions, when these clients encounter a Routing header within an encapsulated IPv6 packet, they are programmed to forward the packet to the next hop. This behavior may allow attackers to circumvent standard security configurations of certain Internet gateways that are designed to reject all source-routed packets, thereby increasing the risk of unauthorized access and data breaches.
