Discovered by: Nicolas Pouvesle
At REcon 2008, Nicolas Pouvesle demonstrated some amazing NetWare-Fu with his kernel exploitation techniques and staged payloads for a stack overflow in the DCERPC stack in the NetWare kernel. Besides impressing everyone at the conference (not to mention all of the Quebecois women around Montreal), he also struck fear into the hearts of NetWare administrators everywhere. All three of them.
This vulnerability also shows how there can often be similar vulnerabilities in different implementations of the same functionality. And when a vulnerability in one implementation is found and fixed, similar bugs in other implementations may go unnoticed for a while. What does it take to make a vendor like Novell audit their DCERPC code for simple vulnerabilities? A widespread worm exploiting a stack overflow in the Microsoft DCERPC stack, crippling large portions of the Internet, and supposedly causing a blackout of the entire East Coast of the USA? Apparently not.
