# 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 = $wpdb->get_results("SELECT name, hash FROM <code>{$tblName}</code> WHERE id = {$id}", ARRAY_A);

if ($getResult) {

$row =$getResult[0];

$nameHash = "{$row['name']}_{$row['hash']}";

$delResult = $wpdb->query("DELETE FROM <code>{$tblName}</code> WHERE id = {$id}");

if ($delResult != 0) {

$post['duplicator_delid'] variable is not sanitized
