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-26093.

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

Memory corruption vulnerability in IrfanView CADImage Plugin's DWG file parser due to insufficient validation of user-supplied data during file parsing, allowing remote code execution in the context of the current process.

MitigationAvoid opening untrusted DWG files and monitor for vendor patches to the CADImage plugin; consider disabling the plugin until patched.

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 installation
    Find the IrfanView CADImage plugin (CADImage.dll) in the IrfanView PlugIns folder, typically found in the program directory under a 'plugins' or 'plugins32' subfolder
    Affected if The CADImage.dll file exists in the IrfanView plugins directory, indicating the plugin is installed
  2. Determine the installed 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 version number displayed is lower than 15.0.0.8 (for example, 15.0.0.7 or earlier)
  3. Verify DWG file handling is enabled
    Open IrfanView, go to Options > Plugins, or check the plugin configuration to confirm the CADImage plugin is enabled for image/file operations
    Affected if The CADImage plugin is listed as enabled in IrfanView's plugin settings
  4. Confirm DWG file association or usage
    Check if IrfanView is configured to open .dwg files directly, or if users commonly open DWG files using IrfanView with the CADImage plugin
    Affected if IrfanView is associated with or used to open DWG files, which triggers the vulnerable DWG parser code path

You are affected if the CADImage plugin for IrfanView is installed and its version is below 15.0.0.8, and the plugin is enabled for processing DWG files

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

Avoid opening untrusted DWG files and monitor for vendor patches to the CADImage plugin; consider disabling the plugin until patched.

Recommended fix Moderate confidence

Cadimage version 15.0.0.8 or later

  1. 1. Verify the current version of Cadimage plugin installed by checking the plugin properties in IrfanView
  2. 2. Navigate to the official Cadimage website or authorized distributor to obtain version 15.0.0.8 or later
  3. 3. Download the Cadimage plugin version 15.0.0.8 (or the latest stable version if higher)
  4. 4. Close IrfanView completely before proceeding with the update
  5. 5. Install the new Cadimage plugin version, overwriting the existing installation
  6. 6. Restart IrfanView and verify the new plugin version is loaded correctly
  7. 7. Test DWG file opening functionality to confirm normal operation
