Shopware: Unauthenticated data extraction possible through store-api.order endpoint

Summary

An insufficient check on the filter types for unauthenticated customers allows access to orders of other customers. This is part of the deepLinkCode support on the store-api.order endpoint.

Details

Data Exposure

Depending on the order payload configuration, attackers may retrieve:

• Customer names
• Billing address
• Shipping address
• Email addresses
• Ordered products
• Order values
• Order numbers
• Order dates
• Payment method information
• Shipping method information
• More customs, depending on the given associations in the request

Security Impact

This vulnerability allows:

• Unauthorized access to foreign customer order data
• Mass enumeration of recent orders
• Potential scraping of customer personal information

Limitation

No limitation, but only orders from the past 30 days are checked for changeable means of payment (unrelated).

Impact

The code is present since ~2021. Likely every version since then is impacted for every store.
