Where:

Impact:

Cross Site Scripting, Privilege escalation

Solution Status:

CVE Reference(s):

Description


Gilberto Ficara has reported a security issue and some vulnerabilities in TeamSpeak, which can be exploited by malicious users to gain escalated privileges and by malicious people to conduct cross-site scripting attacks.

1) The problem is that it is possible for a Server Admin to grant certain privileges like "AccessWebAdminServer", "AdminAddServer", "AdminDeleteServer", "AdminStartServer", and "AdminStopServer" to registered users. This can be exploited to create, start, stop, or delete servers by creating a user and accessing certain administrative pages as this user directly.

Successful exploitation requires Server Admin access to the application.

2) Input passed to the "error_title" and "error_text" parameters in error_box.html and to the "ok_title" parameter in ok_box.html is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Successful exploitation requires that the user is currently logged in.

The vulnerabilities are confirmed in version 2.0.20.1. Other versions may also be affected.


Solution:
The vulnerabilities have reportedly been fixed in version 2.0.23.15 BETA.
