Private files publicly accessible with Cloud Storage providers when the hashed URL is known

Patches

We recommend first changing your configuration to set the correct visibility according to the documentation. The visibility must be at the same level as type.

When the Storage is saved on Amazon AWS we recommending disabling public access to the bucket containing the private files: https://docs.aws.amazon.com/AmazonS3/latest/userguide/access-control-block-public-access.html

Otherwise, update to Shopware 6.4.1.1 or install or update the Security plugin (https://store.shopware.com/en/detail/index/sArticle/518463/number/Swag136939272659) and run the command ./bin/console s3:set-visibility to correct your cloud file visibilities

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.
