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 Write 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 write 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-26127.

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 write operation past the end of an allocated buffer. This memory corruption can be triggered by convincing a user to open a specially crafted malicious DWG file, allowing attackers to execute arbitrary code in the context of the current process.

MitigationUsers should avoid opening untrusted DWG files and refrain from visiting untrusted websites that may attempt to deliver malicious DWG content. Keep IrfanView and the CADImage plugin updated when patches become available, or disable the plugin if DWG viewing is not required.

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
    Search for CADImage.dll in the IrfanView installation directory, typically under the 'Plugins' or 'Plugins32' subfolder. Common paths include C:\Program Files\IrfanView\Plugins\CADImage.dll or C:\Program Files (x86)\IrfanView\Plugins\CADImage.dll.
    Affected if The CADImage.dll file exists in the IrfanView Plugins folder, indicating the plugin is installed.
  2. Determine the CADImage plugin version
    Right-click the CADImage.dll file, select Properties, then go to the Details tab to view the File Version. Alternatively, use PowerShell: (Get-Item 'C:\Program Files\IrfanView\Plugins\CADImage.dll').VersionInfo.FileVersion (adjust path if different).
    Affected if The reported version number is less than 15.0.0.8 (for example, 15.0.0.7 or earlier).
  3. Confirm IrfanView is installed
    Check for IrfanView installation by looking for irfanview.exe in Program Files or Program Files (x86), or query the Windows registry under HKLM\SOFTWARE\IrfanView or HKLM\SOFTWARE\WOW6432Node\IrfanView.
    Affected if IrfanView is installed and the vulnerable CADImage plugin is present.

A user is affected if IrfanView with the CADImage plugin version below 15.0.0.8 is installed and the user opens DWG files using this plugin.

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

Users should avoid opening untrusted DWG files and refrain from visiting untrusted websites that may attempt to deliver malicious DWG content. Keep IrfanView and the CADImage plugin updated when patches become available, or disable the plugin if DWG viewing is not required.

Recommended fix Moderate confidence

Cadimage 15.0.0.8 or later

  1. Identify all systems running IrfanView with the Cadimage plugin
  2. Verify the installed Cadimage version is below 15.0.0.8
  3. Obtain Cadimage version 15.0.0.8 or later from the official vendor source
  4. Uninstall or replace the existing Cadimage plugin with the updated version
  5. Confirm the update was successful by checking the plugin version
  6. Test DWG file viewing functionality to ensure the plugin works correctly after the update
  7. Re-scan or reassess the affected systems to verify the vulnerability is remediated
