Multiple cross-site scripting (XSS) vulnerabilities in Mambo Site Server 4.0.12 BETA and earlier allow remote attackers to execute script on other clients via (1) the link parameter in sectionswindow.php, the directory parameter in (2) gallery.php, (3) navigation.php, or (4) uploadimage.php, the path parameter in (5) view.php, (6) the choice parameter in upload.php, (7) the sitename parameter in mambosimple.php, (8) the type parameter in upload.php, or the id parameter in (9) emailarticle.php, (10) emailfaq.php, or (11) emailnews.php.

Mambo Site Server 4.0.11 installs with a default username and password of admin, which allows remote attackers to gain privileges.

The administrator/phpinfo.php script in Mambo Site Server 4.0.11 allows remote attackers to obtain sensitive information such as the full web root path via phpinfo.php, which calls the phpinfo function.

Multiple cross-site scripting (XSS) vulnerabilities in Mambo Site Server 4.0.11 allow remote attackers to execute arbitrary script on other clients via (1) search.php and (2) the "Your name" field during account registration.

globals.php in Mambo Site Server 4.0.14 and earlier, when registerglobals is disabled, allows remote attackers to overwrite variables in the GLOBALS array and conduct various attacks, as demonstrated using the mosConfigabsolutepath parameter to content.html.php for remote PHP file inclusion.
