NVD · unedited
IrfanView CADImage Plugin DXF 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 DXF 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-26113.

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 lacks proper validation of user-supplied data when parsing DXF files, leading to memory corruption. An attacker can exploit this by tricking a user into opening a specially crafted malicious DXF file, allowing arbitrary code execution in the context of the current process.

MitigationApply the vendor patch or update to the CADImage plugin when 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. Confirm IrfanView is installed
    Check if IrfanView is present on the system by looking for the program in standard installation locations (C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView) or by searching for irfanview.exe
    Affected if IrfanView is installed on the system
  2. Locate the CADImage plugin
    Navigate to the IrfanView plugins directory (typically named 'Plugins' within the IrfanView installation folder) and look for CADImage-related DLL files (commonly cadimage.dll or similar)
    Affected if The CADImage plugin DLL exists in the IrfanView plugins folder
  3. Determine CADImage plugin version
    Right-click the CADImage DLL file, select Properties, and view the File Version tab. Alternatively, use a command like 'dir /-C' to check file details or inspect the file properties via PowerShell
    Affected if The plugin version displayed is less than 15.0.0.8
  4. Verify DXF file association or preview capability
    Attempt to open a DXF file in IrfanView or check if DXF thumbnails render in Windows Explorer with IrfanView thumbnails enabled
    Affected if DXF files can be opened, viewed, or thumbnail-rendered through IrfanView or its plugin

The environment is affected if the CADImage plugin version is below 15.0.0.8 and IrfanView with this plugin can process DXF files.

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

Apply the vendor patch or update to the CADImage plugin when available; avoid opening untrusted DXF files from unknown sources.

Recommended fix Moderate confidence

Cadimage version 15.0.0.8 or later

  1. 1. Identify the current version of Cadimage plugin installed on systems
  2. 2. If the installed version is lower than 15.0.0.8, obtain the fixed version 15.0.0.8 or later from the official Cadimage vendor
  3. 3. Uninstall the current Cadimage plugin
  4. 4. Install the updated Cadimage version 15.0.0.8 or newer
  5. 5. Verify the installation was successful and the version is correct
  6. 6. Test that DXF files load correctly in IrfanView after the update
