Software: phpkit Version: 1.6.03 others are probably affected as well. Status: Vendor has been notified weeks ago but refuses to answer or take any actions. phpkit[1] is a simple German cms / portal software written in php similar to phpbb / phpnuke and is quite popular in Germany. All session information is stored in cookies - thus a attacker can easily steal session data or hashed passwords. The forum part has _no_ protection against JavaScript, Object or Java injections - all html-tags appear in the victim's browser. Proof-of-concept code That's odd - <script... ;) The source also seems to be vulnerably to SQL-injections - good luck ;) Workaround: Don't use this software. These guys do not seem to know what they are doing. Keep smiling yanosz [1]http://www.phpkit.de
