TITLE:
TorrentFlux "User-Agent" HTTP Header Script Insertion

SECUNIA ADVISORY ID:
SA22293

VERIFY ADVISORY:
http://secunia.com/advisories/22293/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
TorrentFlux 2.x
http://secunia.com/product/12225/

DESCRIPTION:
Steven Roddis has discovered a vulnerability in TorrentFlux, which
can be exploited by malicious users to conduct script insertion
attacks.

Input passed to the "User-Agent" HTTP header is not properly
sanitised before being used. This can be exploited to insert
arbitrary HTML and script code, which will be executed in an
administrator's browser session in context of an affected site when
the "Activity Log" is viewed.

The vulnerability has been confirmed in version 2.1. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

Grant only trusted users access to the application.
