Windows Security Account Manager (SAM) 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

Windows Security Account Manager (SAM) contains a denial of service vulnerability that could allow an attacker to cause the SAM service to become unresponsive. The specific technical details of the exploitation vector are not provided in the available description.

MitigationApply the relevant Microsoft security updates for CVE-2022-30208 to affected Windows systems, or implement network-level filtering as a compensating control if patches cannot be applied immediately.

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. Check Windows version and build number
    Run 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to obtain the exact Windows version and build number
    Affected if The version matches any of the affected products listed: Windows 10 (all versions including 20h2, 21h1, 21h2, 1607, 1809), Windows 11 (all versions), Windows 7 (all versions), Windows 8.1 (all versions), Windows Rt 8.1 (all versions), Windows Server 2008 (all versions including R2), Windows Server 2
  2. Verify SAM service responsiveness
    Run 'sc query sam' to check the status of the Security Account Manager service. Also run 'Get-Service -Name SamSs' in PowerShell to confirm the service is running without hangs or timeouts
    Affected if The SAM service fails to start, hangs, or becomes unresponsive after a period of operation, or shows a stopped state when it should be running
  3. Confirm security update is installed
    Run 'Get-HotFix -Id KB5015013' or check Windows Update history for June 2022 security updates. Alternatively, run 'wmic qfe list' to list all installed quick fix engineering updates
    Affected if The specific security update for CVE-2022-30208 (June 2022 cumulative update) is NOT installed and the Windows version matches the affected product list

A system is likely affected if it runs a Windows version from the affected product list and does NOT have the June 2022 security update installed, or if the SAM service exhibits unexpected unresponsiveness.
