Detailsinfo

A vulnerability classified as problematic was found in TeamSpeak Server (version unknown). This vulnerability affects the function PacketHandler::inINITPacket_SolvePuzzle. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect availability.

The weakness was shared 08/12/2016 by Hanz Jenson as not defined mailinglist post (Full-Disclosure). The advisory is available at seclists.org. The vendor was not involved in the coordination of the public release. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details and also a private exploit are known. The advisory points out:

In PacketHandler::inINITPacket_SolvePuzzle we initialize a ParameterParser. It keeps a vector of parameters. Later, in ServerParser::inPacket, we call ParameterParser::getParam to get the parameter at index 0. However it's possible to send just the string " " which will result in the ParameterParser vector having zero entries. Then this zero-indexing will go out of bounds.

It is declared as proof-of-concept. The advisory illustrates:

This is unfortunately a DoS at best since the retrieved parameter is just compared against "clientinitiv", which isn't terribly useful.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
