We have just released a very important security update for the TeamSpeak 3 Client addressing a RFI (Remote File Inclusion) vulnerability. Please upgrade your desktop clients to version 22.214.171.124 immediately. The update is available for Windows, Linux and OS X. Mobile clients for Android and iOS are not affected by this issue.
You can use the auto-update feature to grab this new release. If you need an installer, please refer to our Downloads page.
Here's the full changelog:
=== Client Release 126.96.36.199 10 Oct 2015
! Hotfix release to fix security vulnerability
*** IMPORTANT ***
We strongly recommend that all server providers and admins change the minimum desktop client version for users required to connect to the server. Unfortunately, this will also prevent mobile clients to connect for now. We'll release updates to Google Play and the Apple App Store as soon as possible (see updates below).
If you don't want to (or can't) increase the minimum client version on your server, you can prevent users from exploiting this vulnerability by revoking the permissions to create channels with descriptions on your server.
There are two ways to increase the minimum client version:
1. Update Server Settings via ServerQuery
Use the following commands via ServerQuery (per default running on TCP port 10011) to do this:
No restart is required when you're using ServerQuery to change the settings.
// authenticate with your serveradmin account (generated during initial server start)
login username password
// change default settings for virtual servers you create in the future
// repeat this for all existing virtual servers in the TeamSpeak instance
2. Update Server Settings via SQL
If you have access to your servers database (SQLite or MySQL) you can use this SQL query to update all virtual servers at once:
You need to restart the server afterwards so the settings will be reload.
UPDATE server_properties SET value = '1444491275' WHERE ident = 'virtualserver_min_client_version';
We sincerely apologize for any inconvenience caused.
*** UPDATE 01 ***
An updated Android client has just been pushed to Google Play and will be available in the next few hours.
*** UPDATE 02 ***
The Android client update is now live. In addition to a new build number, it introduces Android 6.0 compatibility.
*** UPDATE 03 ***
The iOS client has been sumbitted to the Apple App Store and we're waiting for approval.
Apple usual needs 7-14 days for this.
