Detailsinfo

A vulnerability, which was classified as critical, has been found in Shopware. Affected by this issue is some unknown functionality. The manipulation with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Shopware is an open source commerce platform based on Symfony Framework and Vue js. In a Twig environment **without the Sandbox extension**, it is possible to refer to PHP functions in twig filters like `map`, `filter`, `sort`. This allows a template to call any global PHP function and thus execute arbitrary code. The attacker must have access to a Twig environment in order to exploit this vulnerability. This 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. Users are advised to upgrade. Users of major versions 6.1, 6.2, and 6.3 may also receive this fix via a plugin.
