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 Out-Of-Bounds Read 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 read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26413.

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 when parsing DWG files, leading to an out-of-bounds read past the end of an allocated buffer. This memory corruption can be weaponized to achieve remote code execution in the context of the current process. Exploitation requires user interaction—either visiting a malicious webpage or opening a crafted DWG file.

MitigationAvoid opening untrusted or unverified DWG files until a patch is available from IrfanView. Keep antivirus software updated and monitor for security advisories from the vendor.

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. Identify if IrfanView is installed
    Search for IrfanView installation directories on the system, typically under Program Files or Program Files (x86), or check common application data locations.
    Affected if IrfanView is present and the CADImage plugin is used for handling DWG files.
  2. Locate the CADImage plugin
    Find the CADImage plugin file (commonly named cadimage.dll or similar) within the IrfanView plugins folder structure.
    Affected if The CADImage plugin file exists in the IrfanView installation.
  3. Retrieve the CADImage plugin version
    Right-click the plugin file, select Properties, and view the Version tab to obtain the file version information, or use command-line tools to query file metadata.
    Affected if The plugin version displayed is below 15.0.0.8.
  4. Confirm DWG file handling is enabled
    Check if DWG file associations or preview functionality are configured in IrfanView, or verify that the CADImage plugin is loaded when opening DWG files.
    Affected if The plugin processes DWG files and is loaded by IrfanView.

The environment is affected if IrfanView with the CADImage plugin (cadimage.dll) version below 15.0.0.8 is installed and configured to handle DWG files.

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

Avoid opening untrusted or unverified DWG files until a patch is available from IrfanView. Keep antivirus software updated and monitor for security advisories from the vendor.

Recommended fix Moderate confidence

Cadimage 15.0.0.8 or later

  1. Identify the currently installed Cadimage version through the application's 'About' or 'Help' menu
  2. Download the latest version of Cadimage from the official vendor website or trusted software distribution channel
  3. Close all instances of IrfanView and any applications using the CADImage plugin
  4. Run the Cadimage installer and follow the prompts to complete the upgrade
  5. Verify the installed version is 15.0.0.8 or higher after installation
