Realistically, it doesn't need a hole to communicate. All it needs to do is impersonate a player that doesn't mind dying alot. It can still communicate with it's "team-mates" using the built-in communications channels in the game and it can still use CS servers as a directory service. These are FEATURES of the game with no vulnerability required.

Now, the bug was reported to VALVe on April 18th 2003, but it didnt hit bugtraq until July 29th, 2003[2]. On the other hand though, alot of server admins(from what I can grasp from the hlds_linux mailing list) do not run x.1.1.1d for the simple fact that it uses a bit more CPU then x.1.1.0c. There is an unoffical patch for x.1.1.0c that does plug the hole. Unless this worms communicating with an unknown hole or something...
