Arbitrary file deletion via uncanonicalized bucket paths
Published Oct 19, 2023 · Updated Aug 2, 2024
Path traversal in the Yamcs 5.8.6 storage API allows remote attackers to delete arbitrary server files via HTTP DELETE requests. The bucket-object endpoint accepts traversal segments in an object path and resolves the pathname without enforcing the bucket's canonical base directory before deletion. No authentication or user interaction is required, and deletion is limited to files writable by the Yamcs server process.
