Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A flaw was found in Openstack manilla owning a Ceph File system "share", which enables the owner to read/write any manilla share or entire file system. The vulnerability is due to a bug in the "volumes" plugin in Ceph Manager. This allows an attacker to compromise Confidentiality and Integrity of a file system. Fixed in RHCS 5.2 and Ceph 17.2.2.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A broken access control vulnerability in the Ceph Manager volumes plugin allows a Manila share owner to bypass authorization and read/write to any Manila share or the entire Ceph filesystem, rather than being restricted to their own assigned share. This is a privilege escalation issue in the OpenStack Manila Ceph integration.

MitigationUpgrade to RHCS 5.2 or Ceph 17.2.2 or later to obtain the fixed Ceph Manager volumes plugin. Prior to upgrading, verify current share isolation policies and consider network segmentation as a compensating control.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Ceph Manager version
    Run 'ceph mgr module versions' or 'ceph version' to obtain the installed Ceph Manager version
    Affected if The version falls below 15.2.17, 16.2.10, or 17.2.2, or is any version below 5.2 for Red Hat Ceph Storage, or matches Fedora 35 or 36 with Ceph integration
  2. Confirm Manila Ceph integration is active
    Check if OpenStack Manila is deployed and configured to use a Ceph backend by reviewing Manila configuration files or running 'manila service-list' to identify share backends
    Affected if Manila is configured with a CephFS backend driver (such as CephFS via cephfsnative or cephfs)
  3. Verify volumes plugin is enabled
    Run 'ceph mgr module ls' to list enabled Ceph Manager modules, then check if the 'volumes' plugin appears in the enabled list
    Affected if The volumes module is loaded and active in the Ceph Manager configuration
  4. Check Manila share isolation
    Test share access controls by creating two shares under different owner accounts and attempting cross-owner read/write operations, or review Manila share access rules and Ceph filesystem capabilities for the share paths
    Affected if Shares created by one owner can be accessed or modified by another Manila user who is not the owner, indicating broken authorization enforcement
  5. Review Ceph filesystem permissions for Manila shares
    Inspect the Ceph filesystem layout under the Manila share pool (typically /volumes or similar) using 'ceph fs ls' and 'ceph auth list' to verify path-based restrictions
    Affected if Cephx keys or filesystem caps permit broader access than the specific share path assigned to a user, or if no path restrictions are enforced

The environment is affected if Ceph Manager runs a version prior to 15.2.17, 16.2.10, or 17.2.2 (or prior to 5.2 for Red Hat Ceph Storage), Manila uses a Ceph backend, and the volumes plugin is enabled, allowing unauthorized cross-tenant share access.

Upgrade available Upgrade to 5.2 / 15.2.17 / 16.2.10 or later
Fixed in 5.215.2.1716.2.10
Interim mitigation

Upgrade to RHCS 5.2 or Ceph 17.2.2 or later to obtain the fixed Ceph Manager volumes plugin. Prior to upgrading, verify current share isolation policies and consider network segmentation as a compensating control.

Recommended fix High confidence

Ceph 17.2.2 (or 16.2.10/15.2.17 depending on current branch); RHCS 5.2

  1. 1. Identify the current Ceph version by running 'ceph --version' or 'rpm -q ceph-common'
  2. 2. Determine which Ceph release branch you are running (15.x/Quincy, 16.x/Quincy, or 17.x/Quincy)
  3. 3. For Ceph >= 15.0.0 and < 15.2.17: Upgrade to version 15.2.17
  4. 4. For Ceph >= 16.0.0 and < 16.2.10: Upgrade to version 16.2.10
  5. 5. For Ceph >= 17.0.0 and < 17.2.2: Upgrade to version 17.2.2
  6. 6. For RHCS (Red Hat Ceph Storage): Upgrade to version 5.2
  7. 7. For Fedora 35/36: Apply vendor patches when available or upgrade to a patched Ceph version
  8. 8. After upgrade, verify the fix by checking 'ceph --version' shows the patched release
Caveat Upgrading Ceph versions may require cluster restart and compatibility checks with existing clients/applications; ensure backup and test in staging first
