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. Confirm IrfanView 64-bit installation
    Check for IrfanView 64-bit in Program Files (typically C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView) or use system inventory tools to detect the installed software
    Affected if IrfanView 64-bit version 4.50 is installed
  2. Verify IrfanView version
    Open IrfanView, go to Help > About, or check the version property of irfanview.exe in the installation directory
    Affected if Version displayed is exactly 4.50
  3. Detect BabaCAD4Image plugin presence
    Check the IrfanView plugins folder (typically [InstallDir]\plugins\) for BabaCAD4Image.dll or babaCAD4Image.* files; alternatively, in IrfanView go to Properties > Plugins to list loaded plugins
    Affected if BabaCAD4Image plugin is present in the plugins directory or listed in IrfanView's plugin list
  4. Confirm plugin version is 1.3
    Right-click the BabaCAD4Image.dll file, select Properties, and check the File Version tab; or check version info through command line tools like powershell (Get-Item).VersionInfo
    Affected if The plugin file shows version 1.3
  5. Check .dwg file association or support
    In IrfanView, attempt to open a .dwg file or check File > Open dialog for .dwg extension visibility; also check if the plugin handles .dwg in IrfanView's plugin information
    Affected if IrfanView can load or preview .dwg files through the BabaCAD4Image plugin

A user is affected if they have IrfanView 64-bit version 4.50 with BabaCAD4Image plugin version 1.3 installed and .dwg file support is enabled in the plugin.
