Windows Cluster Shared Volume (CSV) Denial of Service Vulnerability

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 · moderate confidence

This is a denial of service vulnerability in Windows Cluster Shared Volume (CSV) functionality. An authenticated attacker could exploit this to cause a denial of service condition on affected Windows Server systems running CSV. The medium severity reflects the limited scope of impact (DoS only, requires authentication).

MitigationApply the Microsoft security update for CVE-2022-24484 to all affected Windows Server systems running Cluster Shared Volumes, following proper failover clustering maintenance procedures.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 the installed Windows Server version
    Run 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' from an elevated command prompt to determine the exact Windows Server version and build number.
    Affected if The installed version matches Windows Server 2012, 2012 R2, 2016, 20H2, 2019, or 2022.
  2. Verify if the system is configured as a failover cluster
    Run 'Get-Cluster' from PowerShell (requires Failover Clustering module) or check the Failover Clustering feature status in Server Manager under 'Add roles and features'.
    Affected if The system is a member of a failover cluster or has the Failover Clustering feature installed.
  3. Determine if Cluster Shared Volumes (CSV) is enabled
    Run 'Get-ClusterSharedVolume -Cluster <clustername>' in PowerShell on a cluster node, or inspect the cluster object in Failover Cluster Manager under 'Cluster Shared Volumes'.
    Affected if One or more CSV volumes are present and online on the cluster.
  4. Confirm the specific build number is within the affected range
    Run 'winver' or 'systeminfo' to obtain the full build number (e.g., 10.0.14393 for Windows Server 2016). Compare against Microsoft's official CVE-2022-24484 bulletin for the exact build numbers addressed by the security update.
    Affected if The build number is earlier than the security update patch level for the respective Windows Server version.

The system is affected if it runs an affected Windows Server version (2012 through 2022), is configured as part of a failover cluster, and has Cluster Shared Volumes (CSV) enabled, with a build number predating the CVE-2022-24484 security patch.
