CVE-2024-42356

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.

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.

Untrusted input is evaluated as executable code within the application's runtime environment. Typical impact: arbitrary code execution within the application's privilege context.

CVE-2024-42356 has a CVSS score of 8.3 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (6.5.8.13, 6.6.5.1); upgrading removes the vulnerable code path.

Update to Shopware 6.6.5.1 or 6.5.8.13

1. What is CVE-2024-42356? CVE-2024-42356 is a high-severity code injection vulnerability in shopware/core (composer), affecting versions <= 6.5.8.12. It is fixed in 6.5.8.13, 6.6.5.1. Untrusted input is evaluated as executable code within the application's runtime environment.
2. How severe is CVE-2024-42356? CVE-2024-42356 has a CVSS score of 8.3 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which packages are affected by CVE-2024-42356?
   • shopware/core (composer) (versions <= 6.5.8.12)
   • shopware/platform (composer) (versions <= 6.5.8.12)
4. Is there a fix for CVE-2024-42356? Yes. CVE-2024-42356 is fixed in 6.5.8.13, 6.6.5.1. Upgrade to this version or later.
5. Is CVE-2024-42356 exploitable, and should I be worried? Whether CVE-2024-42356 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2024-42356 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2024-42356?
   • Upgrade shopware/core to 6.5.8.13 or later
   • Upgrade shopware/platform to 6.5.8.13 or later
   • Upgrade shopware/platform to 6.6.5.1 or later
