Do not keep buckets in the default project on servers that issue restricted client certificates, or rotate the keys of any bucket a restricted client may have accessed.
Technical details
An improper authorization vulnerability in the TLS authorizer allows restricted client certificates to access storage bucket key endpoints that should require elevated permissions. The GET /1.0/storage-pools/{pool}/buckets/{bucket}/keys and related endpoints return S3 access and secret keys when queried by restricted clients with can_view permissions on default project buckets. Attackers can exploit this by querying these endpoints to obtain credentials and then directly interact with the S3 backend. The vulnerability does not affect OpenFGA-based deployments.
Affected products
- LXC Incus 6.0.3 before 6.0.7, 6.6.0 before 7.0.2, 7.1.0 before 7.5.0
