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-26411.

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 DWG file parsing, leading to memory corruption. An attacker can exploit this by tricking a user into opening a malicious DWG file, allowing arbitrary code execution within the context of the current process.

MitigationUntil an official vendor patch is released, avoid opening untrusted DWG files and consider disabling or removing the CADImage plugin if possible. Monitor for IrfanView plugin updates.

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
    Navigate to the IrfanView plugins directory (typically C:\Program Files\IrfanView\Plugins or C:\Program Files (x86)\IrfanView\Plugins) and search for files named CADImage.dll, cadimage.dll, or similar. Also check the main IrfanView folder for CADImage plugin files.
    Affected if The CADImage plugin DLL file is present on the system
  2. Check the CADImage plugin version
    Right-click the CADImage DLL file, select Properties, then go to the Details tab. Look for the File Version or Product Version field. Compare this version number to 15.0.0.8.
    Affected if The installed version is lower than 15.0.0.8 (for example, 14.0.0.0, 15.0.0.7, etc.)
  3. Verify DWG file handling capability
    Check if the CADImage plugin is configured to handle DWG files. Open IrfanView, go to Options > Properties/Settings > Plug-ins, or attempt to open a DWG file with IrfanView. DWG files should be listed as a supported format if the plugin is active.
    Affected if DWG files can be opened or previewed through IrfanView using the CADImage plugin
  4. Check for recent plugin updates
    In IrfanView, go to Options > Properties/Settings > Plug-ins and note the version information displayed. Alternatively, check the IrfanView plugins download page for the latest CADImage plugin version.
    Affected if The version shown in IrfanView matches the vulnerable version range (< 15.0.0.8)

If the CADImage plugin is installed and its version is lower than 15.0.0.8 while DWG file handling is enabled, the system is affected by this vulnerability.

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

Until an official vendor patch is released, avoid opening untrusted DWG files and consider disabling or removing the CADImage plugin if possible. Monitor for IrfanView plugin updates.

Recommended fix Moderate confidence

Cadimage 15.0.0.8 or later

  1. Identify the current version of the Cadimage plugin installed with IrfanView
  2. Navigate to the official Cadimage website or authorized distribution channel to obtain the latest version
  3. Download Cadimage version 15.0.0.8 or later
  4. Close IrfanView if currently running
  5. Install the updated Cadimage plugin by replacing the existing plugin files
  6. Restart IrfanView and verify the plugin loads correctly
  7. Avoid opening untrusted DWG files from unknown or untrusted sources as a precautionary measure until the update is applied
