I had the opportunity to test it on Call of Duty and it didn't work. However, further testing of my program uncovered a bigger problem that needs to be fixed. When run it knocks the server internet offline, and then the attacker. But it only does this to Jedi Servers it seems. So I'll fix that before I get ready to release the source code.
[Edit] I'd like to add that my proof of concept does not require the attacker to actually be inside of a game, nor does it require an install. Here is a video of what the server would see while running the exploit(with the internet knock out bug intact.).
