"The installation of phpMyFAQ on the remote host allows for bypassing
authentication or escalating privileges via the 'admin/attachment.php'
and 'admin/editor/plugins/ImageManager/images.php' scripts.  By
leveraging these issues, a remote attacker can upload files, possibly
even containing arbitrary code, subject to the privileges of the web
server user ID. 

Note that successful exploitation of these issues requires PHP's
'register_globals' setting to be enabled.");
