Shopware vulnerable to Improper Control of Generation of Code in Twig rendered views

Impact

In Twig environment without the Sandbox extension, it is possible to refer to PHP functions in twig filters like map, filter, sort. This allows in the template to call any global PHP function.

Patches

The problem has been fixed with 6.4.18.1 with an override of the specified filters until the integration of the Sandbox extension has been finished.

Workarounds

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