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-26118.

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 suffers from a memory corruption vulnerability during DWG file parsing due to insufficient validation of user-supplied data. An attacker can exploit this by tricking a user into opening a specially crafted malicious DWG file, leading to arbitrary code execution within the context of the current process.

MitigationApply the vendor patch or update to the CADImage plugin when available. Until then, avoid opening untrusted DWG files from unknown or untrusted 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. Check if IrfanView is installed
    Search for IrfanView installation directory in standard locations (Program Files or Program Files x86) or check registry for uninstall entries
    Affected if IrfanView is present on the system
  2. Locate the CADImage plugin
    Look for CadImage or cadimage DLL files in the IrfanView plugins subdirectory
    Affected if The CADImage plugin DLL file exists in IrfanView's plugins folder
  3. Determine the CADImage plugin version
    Right-click the CADImage DLL file, select Properties, and check the File Version or Product Version field in the Details tab
    Affected if The reported version number is lower than 15.0.0.8
  4. Verify the plugin is registered and active
    Open IrfanView, go to Options > Settings > Plugins, and confirm the CADImage plugin is loaded and enabled
    Affected if The plugin shows as loaded and enabled in IrfanView's plugin list
  5. Check DWG file association
    Attempt to open a DWG file in IrfanView or check if DWG files are associated with IrfanView using the CADImage plugin handler
    Affected if DWG files can be opened directly through IrfanView using the CADImage plugin

The environment is affected if the CADImage plugin version is below 15.0.0.8 and the plugin is loaded and capable of opening DWG files in IrfanView.
