Echo: ceph: security update to 20.2.4+ds-1

high Tenable Cloud Security Plugin ID 478672

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2026-54330)

Solution

Update the ceph library and its related packages to version 20.2.4+ds-1 or later.
