CVE-2024-42356

Shopware is an open commerce platform. Prior to versions 6.6.5.1 and 6.5.8.13, the context variable is injected into almost any Twig Template and allows to access to current language, currency information. The context object allows also to switch for a short time the scope of the Context as a helper with a callable function. The function can be called also from Twig and as the second parameter allows any callable, it's possible to call from Twig any statically callable PHP function/method. It's not possible as customer to provide any Twig code, the attacker would require access to Administration to exploit it using Mail templates or using App Scripts. Update to Shopware 6.6.5.1 or 6.5.8.13 to receive a patch. For older versions of 6.1, 6.2, 6.3 and 6.4 corresponding security measures are also available via a plugin.

Impact

The context variable is injected into almost any Twig Template and allows to access to current language, currency information. The context object allows also to switch for a short time the scope of the Context as a helper with a callable function.

Example call from PHP:

$context->scope(Context::SYSTEM_SCOPE, static function (Context $context) use ($mediaService, $media, &$fileBlob): void {
    $fileBlob = $mediaService->loadFile($media->getId(), $context);
});

This function can be called also from Twig and as the second parameter allows any callable, it's possible to call from Twig any statically callable PHP function/method.

It's not possible as customer to provide any Twig code, the attacker would require access to Administration to exploit it using Mail templates or using App Scripts.

Patches

Update to Shopware 6.6.5.1 or 6.5.8.13

Workarounds

For older versions of 6.1, 6.2, 6.3 and 6.4 corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.
