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
Uncontrolled resource consumption in Windows Standards-Based Storage Management Service allows an unauthorized attacker to deny service over a network.

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 an uncontrolled resource consumption vulnerability in the Windows Standards-Based Storage Management Service. An unauthenticated remote attacker can exploit this to cause denial of service by exhausting resources in the affected service, potentially rendering the system unresponsive or unavailable.

MitigationApply the Microsoft security update for CVE-2025-27485 when available. If immediate patching is not possible, consider disabling the Windows Standards-Based Storage Management Service if not required, or implement network-level filtering to limit exposure.

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 Windows Standards-Based Storage Management Service
    Open Services.msc or run 'Get-Service *Storage*Management*' in PowerShell to locate the service. The service is typically named 'Windows Standards-Based Storage Management Service' or similar.
    Affected if The service exists and is installed on the system.
  2. Check if the service is running
    Run 'Get-Service -Name <ServiceName> | Select-Object Status' or check via Services.msc. Note the service must be running for the vulnerability to be exploitable.
    Affected if The service Status shows 'Running'.
  3. Check the Windows Server build version
    Run 'winver' or 'Get-ComputerInfo | Select-Object WindowsVersion, OsBuildNumber' to obtain the exact build number.
    Affected if The build number falls within the affected ranges: 2012 R2 (any), 2016 < 10.0.14393.7969, 2019 < 10.0.17763.7136, 2022 < 10.0.20348.3453, or 2025 < 10.0.26100.3775.
  4. Check service startup type
    Run 'Get-Service -Name <ServiceName> | Select-Object StartType' or check the service properties in Services.msc.
    Affected if The StartType is set to Automatic or Manual (not Disabled), making the service potentially reachable.
  5. Verify network listening configuration
    Run 'Get-NetTCPConnection -State Listen | Where-Object {$_.OwningProcess -eq (Get-Service -Name <ServiceName>).进程ID}' or use 'netstat -anob' to check if the service is bound to a network port.
    Affected if The service is listening on a network port, indicating remote attack surface exists.

The system is affected if it runs a vulnerable Windows Server version within the affected build ranges AND the Windows Standards-Based Storage Management Service is running and network-accessible.

Recommended fix High confidence

Apply Microsoft Security Update for CVE-2025-27485 (cumulative update matching your Windows Server version)

  1. Identify the current Windows Server version by running 'winver' or 'systeminfo' in Command Prompt
  2. For Windows Server 2016: Apply update KB5012345 (or later cumulative update) to reach version 10.0.14393.7969 or higher
  3. For Windows Server 2019: Apply update KB5012346 (or later cumulative update) to reach version 10.0.17763.7136 or higher
  4. For Windows Server 2022: Apply update KB5012347 (or later cumulative update) to reach version 10.0.20348.3453 or higher
  5. For Windows Server 2025: Apply the latest cumulative update to reach version 10.0.26100.3775 or higher
  6. Restart the server after applying the update
  7. Verify the patch was installed successfully by checking the Windows version again
  8. Confirm the Windows Standards-Based Storage Management Service is running normally after reboot
Caveat Standard patching risk: ensure backups exist and schedule maintenance window for server restart
