Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
IrfanView CADImage Plugin DWG File Parsing Memory Corruption Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of IrfanView CADImage Plugin. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of DWG files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26100.

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 · high confidence

The CADImage plugin in IrfanView fails to properly validate user-supplied data when parsing DWG files, leading to memory corruption. An attacker can exploit this by crafting a malicious DWG file that, when opened by a victim, triggers an out-of-bounds write or buffer overflow, allowing arbitrary code execution in the context of the current process.

MitigationAvoid opening untrusted or unverified DWG files. Update IrfanView and the CADImage plugin when patches become available. Consider disabling or removing the CADImage plugin if DWG viewing is not required.

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 if IrfanView is installed
    Look for IrfanView installation directory (commonly C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView) or search for irfanview.exe using file explorer or command: dir /s /b C:\irfanview.exe 2>nul
    Affected if IrfanView is present on the system
  2. Locate the CADImage plugin
    Check for CADImage plugin files in the IrfanView plugins folder (typically C:\Program Files\IrfanView\Plugins or similar). Look for files named CadImage.dll, cadimage.dll, or similar CADImage-related DLLs
    Affected if CADImage plugin DLL is present in the IrfanView plugins directory
  3. Identify the CADImage plugin version
    Right-click the CADImage DLL file, select Properties, then go to the Details tab to view the File Version. Alternatively, use PowerShell: (Get-Item 'C:\Program Files\IrfanView\Plugins\CadImage.dll').VersionInfo
    Affected if The displayed version number is lower than 15.0.0.8 (for example, 15.0.0.7, 14.x.x.x, etc.)
  4. Verify DWG file association or preview capability
    Check if IrfanView can display DWG thumbnails or has DWG listed in its supported formats. Try opening a DWG file with IrfanView or check File > Properties in IrfanView for registered image types
    Affected if IrfanView can open or preview DWG files using the CADImage plugin
  5. Check for recent DWG file access
    Review browser download history, recent documents, or email attachments for DWG files downloaded from untrusted sources. Use PowerShell: Get-ChildItem -Path $env:USERPROFILE\Downloads -Filter *.dwg -ErrorAction SilentlyContinue | Select-Object Name, LastWriteTime
    Affected if DWG files from untrusted or unknown sources have been opened with IrfanView recently

The system is affected if IrfanView with a CADImage plugin version lower than 15.0.0.8 is installed and has been used to open DWG files.

Upgrade available Upgrade to 15.0.0.8 or later
Fixed in 15.0.0.8
Interim mitigation

Avoid opening untrusted or unverified DWG files. Update IrfanView and the CADImage plugin when patches become available. Consider disabling or removing the CADImage plugin if DWG viewing is not required.

Recommended fix High confidence

Cadimage 15.0.0.8 or later

  1. Verify the current version of the CADImage plugin installed with IrfanView
  2. Download Cadimage version 15.0.0.8 or later from the official vendor website
  3. Uninstall the existing CADImage plugin
  4. Install the updated CADImage plugin version 15.0.0.8 or newer
  5. Restart IrfanView and verify the plugin loads correctly
  6. Avoid opening untrusted DWG files until the update is applied
