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 DXF File Parsing Out-Of-Bounds Read 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 DXF files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26430.

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 during DXF file parsing, leading to an out-of-bounds read vulnerability. This allows attackers to read memory past the end of an allocated buffer, which can be leveraged to achieve remote code execution in the context of the current process.

MitigationApply the vendor patch for the CADImage plugin or disable/remove the plugin until a patch is available; avoid opening untrusted DXF files from unknown sources.

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. Locate the CADImage plugin file
    Open IrfanView installation directory and navigate to the 'Plugins' or 'Plugins32' folder. Look for a DLL file related to CAD or DXF support, typically named 'CADImage.dll' or similar.
    Affected if The CADImage.dll or CAD-related DLL is present in the plugins folder, indicating the plugin is installed
  2. Check the CADImage plugin version
    Right-click on the CADImage DLL file, select Properties, then go to the Details tab to view the File Version. Alternatively, use PowerShell: (Get-Item 'C:\Path\To\Plugins\CADImage.dll').VersionInfo.FileVersion
    Affected if The version number is lower than 15.0.0.8 (for example, 15.0.0.7, 14.x.x.x, or any version that does not match 15.0.0.8 or higher)
  3. Confirm the plugin is active
    Open IrfanView, go to Options > Properties/Settings > Plugins. Look for the CAD/DXF plugin listed as loaded and enabled. Or check if the plugin DLL is not renamed with a disabled extension (like .dll.bak).
    Affected if The CADImage plugin appears as loaded/enabled in IrfanView's plugin list
  4. Verify DXF file association or support
    Check if IrfanView can open or preview .dxf files, or if the plugin is associated with DXF file handling. In IrfanView, try Options > File types or check if .dxf appears in the list of supported image types.
    Affected if DXF file support is enabled and the CADImage plugin handles DXF parsing

If the CADImage plugin DLL is present in the IrfanView plugins folder with a version lower than 15.0.0.8, and DXF file support is enabled, the environment is vulnerable to this CVE.

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

Apply the vendor patch for the CADImage plugin or disable/remove the plugin until a patch is available; avoid opening untrusted DXF files from unknown sources.

Recommended fix Moderate confidence

Cadimage 15.0.0.8

  1. 1. Identify all systems with Cadimage (IrfanView CADImage Plugin) installed
  2. 2. Check current Cadimage version - look for version information in the plugin or IrfanView about dialog
  3. 3. If installed version is below 15.0.0.8, download Cadimage version 15.0.0.8 or later from the official vendor source
  4. 4. Back up any existing Cadimage installations and custom configurations
  5. 5. Install the upgraded Cadimage version 15.0.0.8
  6. 6. Verify the installed version now shows 15.0.0.8 or higher
  7. 7. Test that DXF files load correctly in IrfanView with the updated plugin
Caveat Standard version upgrade - verify custom settings and DXF rendering work as expected after upgrade
