Affected Products:

Contacted Vendor:
----------------------------------------------
I have contacted the vendor on June, 25th 2006 at 12:25 PM via e-mail.

A copy of the e-mail is attached as screenshoot at the end of this text.

Description:
----------------------------------------------
AutoRank PHP is our next generation toplist software, written completely in PHP and backed by a MySQL database.
AutoRank Professional is a complete top list software package. 
It will keep a database of accounts, and the account holders can then send hits to your site.

Requirements:
----------------------------------------------
register_globals = On

Vulnerability:
----------------------------------------------
Input passed to the "Keyword" parameter in "search.php" and "Username" parameter in "main.cgi" isn't 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.


Solution(Against XSS-attacks):
----------------------------------------------
Edit the source code to ensure that input is properly sanitised.
You should work with "htmlspecialchars()" or "strip_tags()" php-function to ensure that html tags
are not going to be executed.

Example:
<?php
  echo htmlspecialchars("<script");
?>

Set "register_globals" to "Off".
