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-26387.

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

A memory corruption vulnerability exists in the IrfanView CADImage Plugin's DWG file parser due to insufficient validation of user-supplied data during file parsing. This allows an attacker to trigger a memory corruption condition that can be leveraged to achieve remote code execution within the context of the current process.

MitigationUsers should avoid opening untrusted DWG files and only open files from trusted sources. Consider disabling or removing the CADImage plugin until an official patch is available from IrfanView.

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. Confirm IrfanView installation
    Locate the IrfanView installation directory (typically C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView) and verify irfanview.exe exists
    Affected if IrfanView is installed on the system
  2. Identify CADImage plugin presence
    Check for the CADImage plugin file (commonly cadimage.dll) in the IrfanView plugin directory (usually C:\Program Files\IrfanView\Plugins or Plugins64)
    Affected if The CADImage plugin file is present in the IrfanView plugins folder
  3. Retrieve CADImage plugin version
    Right-click the cadimage.dll file, select Properties, then navigate to the Details tab to view the File Version. Alternatively, use PowerShell: (Get-Item 'C:\Program Files\IrfanView\Plugins\cadimage.dll').VersionInfo
    Affected if The plugin version is lower than 15.0.0.8 or the version cannot be determined (older installation)
  4. Verify DWG file handling capability
    Attempt to open a DWG file using IrfanView, or check if DWG file associations exist for IrfanView. The vulnerability triggers when parsing a specially crafted DWG file
    Affected if The CADImage plugin can open or preview DWG files through IrfanView

If IrfanView with the CADImage plugin (cadimage.dll) version below 15.0.0.8 is installed and capable of processing DWG files, the environment is affected by this vulnerability.

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 only open files from trusted sources. Consider disabling or removing the CADImage plugin until an official patch is available from IrfanView.

Recommended fix Moderate confidence

Cadimage 15.0.0.8 or later

  1. Upgrade Cadimage plugin to version 15.0.0.8 or later
  2. Verify the installed Cadimage plugin version through IrfanView's 'Help > About Plugins' menu
  3. If using an older version of IrfanView, ensure it is also updated to maintain plugin compatibility
  4. After upgrading, validate that DWG files open correctly in IrfanView with the updated plugin
