Описание

Pimcore vulnerable to disclosure of system and database information behind /admin firewall

Summary

Navigating to /admin/index/statistics with a logged in Pimcore user (not an XmlHttpRequest because of this check: IndexController:125) exposes information about the Pimcore installation, PHP version, MYSQL version, installed bundles and all database tables and their row count in the system.

The web server should not return any product and version information of the components used. The table names and row counts should not be exposed.

Details

/admin/index/statistics returns the following JSON-response:

{ { "instanceId": "...", "pimcore_major_version": 11, "pimcore_version": "v11.3.1", "pimcore_hash": "3ecd39f21dbdd25ffdf4bec6e2c860eccfd3d008", "pimcore_platform_version": "v2024.2", "php_version": "8.3.8", "mysql_version": "10.11.8-MariaDB-ubu2204", "bundles": [ // all installed bundles ], "tables": [ // all tables and their row count, e.g: { "name": "users", "rows": 2 }, ] }

Information about the Pimcore Version can also be seen here:

Impact

Only for logged in Pimcore users possible.

Workaround and Patch

We patched the following additional check for Pimcore v10.6.9. This uses an app-specific class but any user permission would be ok. This resolves navigating to /admin/index/statistics.

diff --git a/vendor/pimcore/pimcore/bundles/AdminBundle/Controller/Admin/IndexController.php b/vendor/pimcore/pimcore/bundles/AdminBundle/Controller/Admin/IndexController.php --- a/vendor/pimcore/pimcore/bundles/AdminBundle/Controller/Admin/IndexController.php (revision dd81ef4c666b18c254333867a60f6ed455025076) +++ b/vendor/pimcore/pimcore/bundles/AdminBundle/Controller/Admin/IndexController.php (date 1721225746781) @@ -15,6 +15,7 @@ namespace Pimcore\Bundle\AdminBundle\Controller\Admin; +use App\Constant\UserPermission; use Doctrine\DBAL\Connection; use Exception; use Pimcore\Analytics\Google\Config\SiteConfigProvider; @@ -142,6 +143,12 @@ throw $this->createAccessDeniedHttpException(); } + $user = $this->tokenResolver->getUser(); + + if (!$user->isAdmin() && !$user->isAllowed(UserPermission::ADMIN_INDEX_VIEW)) { + throw $this->createAccessDeniedException(); + } + // DB try { $tables = $db->fetchAllAssociative('SELECT TABLE_NAME as name,TABLE_ROWS as `rows` from information_schema.TABLES

For the Pimcore versions in the UI we used the IndexActionSettingsEvent. This works for Versions < Pimcore 11:

<?php namespace App\EventListener\Admin; use App\Constant\UserPermission; use Pimcore\Bundle\AdminBundle\Event\AdminEvents; use Pimcore\Event\Admin\IndexActionSettingsEvent; use Pimcore\Security\User\TokenStorageUserResolver; use Symfony\Component\EventDispatcher\EventSubscriberInterface; /** * @deprecated and cannot be used in Pimcore 11 */ class PimcoreVersionUIGuardSubscriber implements EventSubscriberInterface { public function __construct(private readonly TokenStorageUserResolver $tokenResolver) { } public static function getSubscribedEvents() { return [ AdminEvents::INDEX_ACTION_SETTINGS => ['onIndexActionSettingsEvent'], ]; } public function onIndexActionSettingsEvent(IndexActionSettingsEvent $event): void { $user = $this->tokenResolver->getUser(); if ($user->isAdmin() || $user->isAllowed(UserPermission::ADMIN_INDEX_VIEW)) { return; } $settings = $event->getSettings(); $settings['instanceId'] = ''; $settings['version'] = ''; $settings['build'] = ''; $event->setSettings($settings); } }

Pimcore's Admin Classic Bundle provides a backend user interface for Pimcore. Navigating to `/admin/index/statistics` with a logged in Pimcore user exposes information about the Pimcore installation, PHP version, MYSQL version, installed bundles and all database tables and their row count in the system. This vulnerability is fixed in 1.5.2, 1.4.6, and 1.3.10.
