[PersianHacker.NET 200503-09]PHPOpenChat v3.X XSS Multiple Vulnerability
Date: 2005 March
Bug Number: 09

PHPOpenChat
is a high performance php-based chat server software for a live chat-room or 
-module on every php-based site.
More info @:
http://phpopenchat.org/


Discussion:
--------------------
The software does not properly validate user-supplied input in 'regulars.php', 
'register.php'.

A remote user can access the target user's cookies (including authentication 
cookies), if any, associated with the site running the PHPOpenChat software, 
access data recently submitted by the target user via web form to the site, or 
take actions on the site acting as the target user.
