# Description

Wordpress Duplicator 0.5.14 suffers from remote SQL Injection Vulnerability


Location file: /view/actions.php

This is the bugged ajax functions wp_ajax_duplicator_package_delete:

function duplicator_package_delete() {

DUP_Util::CheckPermissions('export');

try {
global $wpdb;
$json = array();
$post = stripslashes_deep($_POST);
$tblName = $wpdb->prefix . 'duplicator_packages';
$postIDs = isset($post['duplicator_delid']) ? $post['duplicator_delid'] : null;
$list = explode(",", $postIDs);
$delCount = 0;

if ($postIDs != null) {

foreach ($list as $id) {
$getResult = $wpdb->get_results("SELECT name, hash FROM `{$tblName}` WHERE id = {$id}", ARRAY_A);
if ($getResult) {
$row = $getResult[0];
$nameHash = "{$row['name']}_{$row['hash']}";
$delResult = $wpdb->query("DELETE FROM `{$tblName}` WHERE id = {$id}");
if ($delResult != 0) {


$post['duplicator_delid'] variable is not sanitized

A authorized user with "export" permission or a remote unauthenticated attacker could
use this vulnerability to execute arbitrary SQL queries on the victim
WordPress web site by enticing an authenticated admin (CSRF)
