Strange bugs

[retrib]

Hello everyone!

I've got 2 problems, maybe smbd can help me here...

First one.
My old version of TeamSpeak server was hacked. Someway one person got rights to make registered channels. That channels contained (probably) some special symbols, that make TS client to crash after logging in and trying to do smth with that channel (join,delete etc). Maybe it was just my mistake with users rights, but anyway, client crashed. So heres a little piece of log for u.

Look what "Duda" done. His channels crashed TS.

The second problem.
I`ve installed the last TS server version and got a litttle problem with it. Maybe i`ve just made a mistake in users rights again... No one of anonymous, registered etc users cannot speak at my server, before i grant his voice rights. Of course i checked AccessVoice option for registered users. How can i fix this terrible problem?

P.s. sorry for my english, i'm russian actually... :o

P.p.s. sorry if i post this in wrong place or just asking dumb questions :rolleyes:

1. Delete usernames that are unkown to you, just a guess on this one

2. Can you give us screen shots of your permissions that you have on right now for registered members. I will be able to help you more this way

Update your server to the lastest version.

Take out the moderated flag.

[retrib]

Pfff. Just found a reason for 2nd bug. Right after posting here :D

I made all channels moderated, so all users must get voice rights granted. I thought "moderated" means, that i can make a CA or operator for that channel. I can't even imagine that all users cannot speak in these channels before confirmation. Sorry for dusturbing with that. Better to put description of "moderated" in manual...

With first problem - of course, i banned IP of that user. But i think theres may be some exploit tool to make this with some versions of TS servers... TS client just print several error messages and exits when you try to connect to hacked channel. Unfortunately, i haven't any screenshots of that errors, but you can see channels names in log. (mb reason in channels names etc)

In your global settings - uncheck public this will help with people trying to hack

[retrib]

Thnx i'll uncheck public listing. Hope some coders will see that strange bug with TS crashing.
My problems solved. Thanks a lot guys!

Hi there,

please update to the newest TS2 Client version, then your client will not crash anymore no matter what weird character sequences channels/clients etc. contain :).

You should get this from the download section:

TeamSpeak 2 Client (Updated Executable)
SHA1: 5b21f93b5574b067ac24515e1d43f7dde3297945
MD5: a19547c94bc7695d1ef53ff8d1db297a
2.0.33.7

Also, updating the server to the newest version helps too, the server will also strip dangerous characters from channels/clients etc.
