# 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)
