Description: The plugin allows you to add multiple images to the gallery, create countless galleries, add a description to each of them, as well as make the same things with video links.
Vulnerability:
The attacker must be logged in with at least manager level access or access to the administrative panel 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 }
