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 Remote Desktop Client version (mstsc.exe)
    Right-click mstsc.exe in %SystemRoot%\System32, select Properties, then view the Details tab for Product Version. Or run: Get-ItemProperty 'C:\Windows\System32\mstsc.exe' | Select-Object VersionInfo
    Affected if Product version is below 1.2.5716.0
  2. Check Microsoft Windows App version
    Open PowerShell and run: Get-AppxPackage -Name Microsoft.RemoteDesktop | Select-Object Name, Version
    Affected if Version is below 2.0.327.0
  3. Check Windows 10 build version
    Open Settings > System > About, or run: winver, or run: [System.Environment]::OSVersion.Version.Build in PowerShell
    Affected if Build number is below 10240.20857 (1507), 14393.7606 (1607), 17763.6659 (1809), 19044.5247 (21h2), or 19045.5247 (22h2)
  4. Check Windows 11 22h2 build version
    Open Settings > System > About, or run: winver, or run: [System.Environment]::OSVersion.Version.Build in PowerShell
    Affected if Build number is below 22621.4602
