Product description:
============
MODX (originally MODx) is a free, open source content management system and web application framework for publishing content on the world wide web and intranets.
============

MODX Revolution Blind SQL Injection (CVE-2014-2736)
============
The application is vulnerable to blind SQL injection which is exploitable through the session ID supplied by the user. This issue is exploitable without authentication.

Details:
----------------------
The vulnerability is triggered where the session ID is inserted into the modx_session table. In this location it is possible to inject SQL sub queries that will be executed by the application.

This issue is exploitable without authentication by passing crafted SQL subqueries into the session ID (PHPSESSID) passed to /index.php. Passing a carefully crafted subquery into the application will cause the application to execute arbitrary SQL queries within the context of database user privileges. Successful injection will cause the application to accept the session and not set a new cookie.

POC is withheld.

Authentication is not required to exploit this issue.
----------------------


MODX Revolution Blind SQL Injection (CVE-2014-2736):
============
The messaging and manager functionalities of MODX, are vulnerable to blind SQL injection. Access to these functions requires privileged access.

Details:
----------------------
1. The 'user' parameter of /connectors/security/message.php is vulnerable to blind SQL injection.
2. The 'id' parameter of /manager/index.php is vulnerable to blind SQL injection.

Authentication is required to exploit these vulnerabilities.
----------------------

The CVE project assigned CVE-2014-2736 to all these issues.

SQL-injection MODX Revolution < 2.5.1
Пример уязвимого сценария

<?php
define('MODX_API_MODE', true);
require dirname(__FILE__) . '/index.php';
$modx->getService('error', 'error.modError');
$modx->setLogLevel(modX::LOG_LEVEL_ERROR);
$modx->setLogTarget('FILE');

try{
    if(empty($_REQUEST['id'])) throw new Exception('Invalid request', 500);
    $doc = $modx->getObject(modResource::class, $_REQUEST['id']);
    if($doc) echo $doc->pagetitle;
    else throw new Exception("Document not found", 404);
}catch(Exception $e){
    $modx->sendError($e->getMessage(), [
        'error_type' => $e->getCode()
    ]);
}

Если $_REQUEST['id'] будет массивом, то мы можем конструировать свои параметры выборки в соответствии с документацией
Но ОРМ будет фильтровать некоторые запросы. Поэтому можно попробовать засунуть скулю в ключ параметра.

$_REQUEST['id']['1 = (SELECT COUNT(*) FROM modx_site_content)']

Можно попробовать сделать выборку UNION. Но такие запросы проходят через фильтрацию

protected function isValidClause($clause) {
        $output = rtrim($clause, ' ;');
        $output = preg_replace("/\\\\'.*?\\\\'/", '{mask}', $output);
        $output = preg_replace('/\\".*?\\"/', '{mask}', $output);
        $output = preg_replace("/'.*?'/", '{mask}', $output);
        $output = preg_replace('/".*?"/', '{mask}', $output);
        return strpos($output, ';') === false && strpos(strtolower($output), 'union ') === false;
}

Соответственно для обхода используем запрос вида

UNION/**/SELECT

Уязвимость древняя еще со времен MODX Revolution 2.2.12 (only). Просто до этого точка входа была в коннекторах ядра, а сейчас сместилась в коннекторы компонентов.
