Changing nickname with hacks - PeppeAC - 07.11.2013

With some hacks is possible to change the nickname in game. It doesn't disconnect the player, but only changes his nickname.

This is part of the server logs.
[20:46:54] [join] Peppe has joined the server (0:127.0.0.1)
// NO DISCONNECT LOG
[20:47:16] [join] OtherName has joined the server (0:127.0.0.1)

What I do clientside is this:
1 Join the server with the nickname Peppe.
2 Use the hack to change the nickname into "OtherName".

In serverside the OnPlayerDisconnect for Peppe isn't called and this can be abused.

Yeah, I have faced this problem before.

Can they spawn even if I return 0 in OnPlayerRequestSpawn?
BTW you can always use that secret native to check for bots. GetPlayerVersion returns invalid version name too for them, while IsPlayerNPC returns false.

Yea, under OnPlayerDisconnect it's really annoying. Perhaps store it under the player connecting, and then under the player disconnecting, get their name, compare it to the variable stored and then if it is, then you can save the user file, if not, then just do a normal kick. Could also set a 10 second timer which loops all the players and makes sure that they're legit named players.

That are not bots.

This is the main problem of this bug, that I temporarily fixed: if a player changes his name in game with this hack, the OnPlayerDisconnect with his previous name will not be called, so in this way I can avoid any saving system.

I've wrote some code that might fix the issue:

However, I can't test it atm. If someone can test it for me then that would be great!

This is the most bad-coded script I ever seen...
