Cross-site scripting (XSS) vulnerability in admin/index.php for Pixelpost 1-5rc1-2 and earlier allows remote attackers to inject arbitrary HTML or web script via the loginmessage parameter.

Pixelpost 1-5rc1-2 and earlier, when register_globals is enabled, allows remote attackers to gain administrator privileges and conduct other attacks by setting the _SESSION["pixelpost_admin"] parameter to 1 in calls to admin scripts such as admin/view_info.php.
