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-26389.

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 during DWG file parsing, leading to memory corruption that can be leveraged for remote code execution in the context of the current process. Exploitation requires a user to open a malicious DWG file.

MitigationAvoid opening untrusted DWG files and monitor for updates to the CADImage plugin that address this validation vulnerability.

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
    Check the IrfanView installation directory (typically in a subfolder named 'plugins') for a DLL file related to CADImage or CAD handling. Common names include CadImage.dll, cadimage.dll, or similar.
    Affected if The CADImage plugin DLL exists in the IrfanView plugins folder
  2. Check the plugin file version
    Right-click the CADImage DLL file, select Properties, then view the Details tab to find the File Version or Product Version field.
    Affected if The version number displayed is lower than 15.0.0.8
  3. Confirm DWG file association is enabled
    In IrfanView, go to Options > Properties/Settings > Plugins to verify the CADImage plugin is loaded and enabled for DWG file handling.
    Affected if The plugin is listed as loaded/enabled and configured to handle DWG files
  4. Verify IrfanView processes DWG files
    Try to open a DWG file in IrfanView or check File > Open to see if DWG appears in the supported file types dropdown.
    Affected if IrfanView can open DWG files using the CADImage plugin

If the CADImage plugin is installed with a version below 15.0.0.8 and is enabled for DWG file handling, the environment is affected by this vulnerability.

Avoid opening untrusted DWG files and monitor for updates to the CADImage plugin that address this validation vulnerability.

Recommended fix High confidence

Cadimage 15.0.0.8 or later

  1. Identify the current Cadimage plugin version installed with IrfanView (check plugin folder or IrfanView > About > Plugins)
  2. Close IrfanView completely if it is currently running
  3. Download the Cadimage plugin version 15.0.0.8 or later from the official CADImage vendor website or authorized distributor
