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 version and build numberRun 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to obtain the exact Windows version and build numberAffected 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
-
Verify SAM service responsivenessRun '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 timeoutsAffected 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
-
Confirm security update is installedRun '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 updatesAffected 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.
