How to Fix CVE-2024-42356

To remediate this vulnerability, upgrade all affected Shopware/core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

shopware/core fixed: 6.5.8.13 
Upgrade shopware/core to 6.5.8.13
shopware/platform fixed: 6.5.8.13 
Upgrade shopware/platform to 6.5.8.13
shopware/platform fixed: 6.6.5.1 
Upgrade shopware/platform to 6.6.5.1
shopware/core fixed: 6.6.5.1 
Upgrade shopware/core to 6.6.5.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for shopware/core

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-42356, inspect your project dependencies for Shopware/core:

inspect dependencies for shopware/core

Analyze the terminal output to locate any version of Shopware/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.5.8.13), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Shopware/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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: ```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.
