CVE-2025-33068
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 · uneditedUncontrolled 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 · high confidenceThis is an uncontrolled resource consumption vulnerability in the Windows Standards-Based Storage Management Service that allows remote unauthenticated attackers to cause denial of service by exhausting system resources over the network.
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 checksWork through these to decide whether this CVE applies to you.
-
Check Windows Server versionRun 'winver' or 'systeminfo' to determine the exact Windows Server version and build numberAffected if Version is Windows Server 2012 R2, or Server 2016 with build < 14393.8148, Server 2019 with build < 17763.7434, Server 2022 with build < 20348.3745, or Server 2025 with build < 26100.4270
-
Verify Standards-Based Storage Management Service existsRun 'Get-Service -Name "StorageManagement"' in PowerShell or check services.msc for the service named 'Windows Standards-Based Storage Management Service'Affected if The service is present on the system (service name: StorageManagement)
-
Check if the service is runningRun 'Get-Service -Name "StorageManagement" | Select-Object Status' or check the service status in services.mscAffected if The service Status is 'Running' - only a running service can be exploited
-
Determine network exposure of the serviceReview Windows Firewall rules or network configuration to check if the service port (TCP 65500-65515 range typically used by SMIS) is exposed to untrusted networks, or if the server is directly internet-facingAffected if The service port is open to untrusted/network-facing interfaces; the vulnerability is exploitable remotely
Your system is affected if it runs a vulnerable Windows Server version from the affected ranges AND has the Windows Standards-Based Storage Management Service installed and running with network exposure.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Apply the relevant Microsoft security update for this vulnerability, or disable the Windows Standards-Based Storage Management Service if not required, and use network segmentation to limit exposure to untrusted networks.
Windows Server 2016: build 10.0.14393.8148 or later | Windows Server 2019: build 10.0.17763.7434 or later | Windows Server 2022: build 10.0.20348.3745 or later | Windows Server 2025: build 10.0.26100.4270 or later
- Open Windows Update on the affected Windows Server system
- Check for and install the latest security updates from Microsoft
- Alternatively, download the specific security update from the Microsoft Catalog (https://catalog.update.microsoft.com) using the KB number corresponding to CVE-2025-33068 for your Windows Server version
- After installation, restart the server as prompted by the update
- Verify the service is running properly and confirm the build number matches or exceeds the fixed version for your Windows Server version
