Critical severity GitHub Reviewed Published Jan 17, 2023 in shopware/shopware • Updated Jan 25, 2023

Package

composer shopware/core (Composer)

Affected versions

<= 6.4.18.0

Patched versions

Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
