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 installed .NET Framework versions
    Open Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full (for .NET 4.x) and HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3\ (for .NET 3.x/2.x). Check the Version value in each subkey to see which versions are installed.
    Affected if Any of the following versions are installed: 3.5, 3.5.1, 3.0, 2.0, 4.6, 4.6.2, 4.7, 4.7.1, 4.7.2, 4.8, or 4.8.1
  2. Check .NET Framework version via PowerShell
    Run Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full' | Select-Object Version, Release in PowerShell. Also check Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3\Setup' for earlier versions.
    Affected if The Version or Release value matches any of the affected versions listed in the CVE (3.5, 3.5.1, 3.0, 2.0, 4.6, 4.6.2, 4.7, 4.7.1, 4.7.2, 4.8, 4.8.1)
  3. List installed features via Windows Features
    Open Control Panel > Programs and Features > Turn Windows features on or off. Look for .NET Framework entries to see which versions are enabled on the system.
    Affected if Any .NET Framework version matching the affected list is present in the Windows features list

A system is affected if it has any of the following .NET Framework versions installed and running: 3.5, 3.5.1, 3.0, 2.0, 4.6, 4.6.2, 4.7, 4.7.1, 4.7.2, 4.8, or 4.8.1
