Dbox 3D Slider Lite <= 1.2.2 - Multiple Authenticated SQL injection

During the security analysis, ThunderScan discovered SQL injection vulnerabilities in Dbox 3D Slider Lite WordPress plugin. The easiest way to reproduce the vulnerabilities is to modify the POST request for the slider rename or reorder and append parts of the SQL query to the current_slider_id parameter, the result being something like “current_slider_id=1 AND SLEEP(5)”. Users that do not have full administrative privileges could abuse the database access the vulnerabilities provide to either escalate their privileges or obtain and modify database contents they were not supposed to be able to. Due to the missing nonce token, the vulnerable code is also directly exposed to attack vectors such as Cross Site request forgery (CSRF). 3.1. SQL injection Function: $wpdb->query() Variable: $_POST[‘current_slider_id’]; Vulnerable URL: http://vulnerablesite.com/wp-admin/admin.php?page=dboxlite-slider-admin File: dbox-slider-lite\settings\sliders.php --------- 66 $slider_id=$_POST[‘current_slider_id’]; … 70 $sql = ‘UPDATE ‘.$slider_meta.’ SET slider_name="’.$slider_name.‘" WHERE slider_id=’.$slider_id; 71 $wpdb->query($sql); --------- 3.2. SQL injection Function: $wpdb->query() Variable: $_POST[‘current_slider_id’]; Vulnerable URL: http://vulnerablesite.com/wp-admin/admin.php?page=dboxlite-slider-admin File: dbox-slider-lite\settings\sliders.php --------- 55 $slider_id=$_POST[‘current_slider_id’]; … 58 $sql = ‘UPDATE ‘.$table_name.’ SET slide_order=’.$i.’ WHERE post_id=‘.$slide_order.’ and slider_id='.$slider_id; 59 $wpdb->query($sql); ---------
