http://www.majorsecurity.de/index_2.php?major_rls=major_rls34

Introduction
============
Developed for Professional Hosting Service Providers (HSP) and Corporate IT Professionals, 
Plesk 8.0 provides the most complete and stable set of features in the industry.
Plesk 8.0 provides the perfect solution for IT service providers to increase clientele and 
customize their systems to meet their corporate customers growing needs for self administration.

More Details
============
Cross Site Scripting(in URL):
Input passed directly to the "get_password.php" and "login_up.php3" file is not 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.

Fix
===
None known

Solution
=============
Edit the source code to ensure that input is properly sanitised.
You should work with "htmlspecialchars()" or "htmlentities()" php-function to ensure that html tags
are not going to be executed. Further it is recommend to set off the "register globals" option in the
"php.ini" on your webserver.

Example:
$pass = htmlentities($_POST['pass']);
$test = htmlspecialchars($_GET('test'));
?>
