Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-524: Use of Cache Containing Sensitive Information, where the code uses a cache that contains sensitive information, but the cache can be read by an actor outside of the intended control sphere. In Shopware/storefront, 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 Symfony Session Handler, pop's the Session Cookie and assign it to the Response. Since Shopware 6.5.8.0 the 404 pages, are cached, to improve the performance of 404 pages. So the cached Response, contains a Session Cookie when the Browser accessing the 404 page, has no cookies yet. The Symfony Session Handler is in use, when no explicit Session configuration has been done. When Redis is in use for Sessions using the PHP Redis extension, this exploiting code is not used. ### Patches Update to Shopware version 6.5.8.7 ### Workarounds Using Redis for Sessions, as this does not trigger the exploit code. Example configuration for Redis ```ini # php.ini session.save_handler = redis session.save_path = "tcp://127.0.0.1:6379" ``` ## Consequences As an guest browser session has been cached on a 404 page, every missing image or directly reaching a 404 page will logout the customer or clear his cart.
