Date: Fri Aug 05 2005 - 09:15:31 CDT
Hackers Center Security Group (http://www.hackerscenter.com/)
Zinho's Security Advisory
Desc: Multiple XSS in phpopenchat 3.0.2
Risk: Medium to High
"PHPOpenChat is a high performance php-based chat server software for a live chat-room or -module on every php-based site."
1. (permanent) XSS hole in profile.php and profile_misc.php
"title" and "content" arguments passed with method POST are not sanitized and can generate a permanent XSS hole thus stealing cookie of anyone viewing the user profile page
2. (permanent) XSS hole due to the previous in userpage.php. A malicious user can manipulate the profile fields and the script will be executed in userpage.php
2. (permanent) XSS hole in mail.php
Probably the most dangerous as it can be directed against a specified user knowing just his nickname.
"subject", "body" and the other email parameters are not sanitized.
3. (temporary) XSS hole in invite.php
"disinvited_chatter" and "invited_chatter"
Vendor has been contacted some days ago but we got no reply so far.
