Summary

ceph vulnerability

Details

It was discovered that the Ceph Object Gateway (RGW) SigV4 handler did not reject requests carrying x-amz- headers that were absent from the signed header set. An attacker holding a presigned URL could possibly use this issue to attach arbitrary unsigned x-amz- headers that RGW would honor, allowing them to escalate their privileges beyond what the URL's signer intended.

UBUNTU-CVE-2026-54330 (CVE-2026-54330)

Vulnerability from osv_ubuntu – Published: 2026-08-28 00:18 – Updated: 2026-10-05 16:29 – Source website

Details

Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the Ceph Object Gateway (RGW) SigV4 handler does not reject requests that carry x-amz- headers absent from the signed header set, allowing anyone holding a presigned URL to attach arbitrary unsigned x-amz- headers that RGW will honor. AWS S3 requires every x-amz-* header on a SigV4 request to be signed and rejects requests bearing additional unsigned headers, but RGW validates only the headers listed in X-Amz-SignedHeaders and ignores any extra ones, so they take effect without being covered by the signature. By adding such headers to a presigned PUT URL, an attacker can grant themselves more capabilities than the URL's signer intended and escalate their privileges. This issue is fixed in versions 20.2.4 and 19.2.6.

  "details": "Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the Ceph Object Gateway (RGW) SigV4 handler does not reject requests that carry x-amz-* headers absent from the signed header set, allowing anyone holding a presigned URL to attach arbitrary unsigned x-amz-* headers that RGW will honor. AWS S3 requires every x-amz-* header on a SigV4 request to be signed and rejects requests bearing additional unsigned headers, but RGW validates only the headers listed in X-Amz-SignedHeaders and ignores any extra ones, so they take effect without being covered by the signature. By adding such headers to a presigned PUT URL, an attacker can grant themselves more capabilities than the URL\u0027s signer intended and escalate their privileges. This issue is fixed in versions 20.2.4 and 19.2.6.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
