Shopware is an open source eCommerce platform. Versions prior to 6.3.5.1 may leak of information via Store-API. The vulnerability could only be fixed by changing the API system, which involves a non-backward-compatible change. Only consumers of the Store-API should be affected by this change. We recommend to update to the current version 6.3.5.1. You can get the update to 6.3.5.1 regularly via the Auto-Updater or directly via the download overview. https://www.shopware.com/en/download/#shopware-6 The vulnerability could only be fixed by changing the API system, which involves a non-backward-compatible change. Only consumers of the Store-API should be affected by this change. Please check your plugins if you have it in use. Detailed technical information can be found in the upgrade information. https://github.com/shopware/platform/blob/v6.3.5.1/UPGRADE-6.3.md#6351 ### Workarounds For older versions of 6.1 and 6.2, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version. https://store.shopware.com/en/detail/index/sArticle/518463/number/Swag136939272659 ### For more information https://docs.shopware.com/en/shopware-6-en/security-updates/security-update-02-2021

Weakness

Extended Description

There are many different kinds of mistakes that introduce information exposures. The severity of the error can range widely, depending on the context in which the product operates, the type of sensitive information that is revealed, and the benefits it may provide to an attacker. Some kinds of sensitive information include:

Information might be sensitive to different parties, each of which may have their own expectations for whether the information should be protected. These parties include:

Information exposures can occur in different ways:

It is common practice to describe any loss of confidentiality as an “information exposure,” but this can lead to overuse of CWE-200 in CWE mapping. From the CWE perspective, loss of confidentiality is a technical impact that can arise from dozens of different weaknesses, such as insecure file permissions or out-of-bounds read. CWE-200 and its lower-level descendants are intended to cover the mistakes that occur in behaviors that explicitly manage, store, transfer, or cleanse sensitive information.

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
