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')); ?> History/Timeline ================ 05.11.2006 discovery of the vulnerabilities 06.11.2006 additional tests with other versions 07.11.2006 contacted the vendor 14.11.2006 advisory is written 15.11.2006 advisory released MajorSecurity ======= MajorSecurity is a German penetration testing and security research project which consists of only one person at the present time.
