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-26385.

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 suffers from a memory corruption vulnerability during DWG file parsing due to insufficient validation of user-supplied data. An attacker can craft a malicious DWG file that, when opened by a victim, triggers improper memory operations leading to arbitrary code execution in the context of the current process.

MitigationUsers should avoid opening untrusted DWG files and disable or remove the CADImage plugin if not required. Monitor for IrfanView and plugin updates 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. Locate the CADImage plugin file
    Search for CADImage DLL files in the IrfanView plugins directory (typically C:\Program Files\IrfanView\Plugins\ or C:\Program Files (x86)\IrfanView\Plugins\) and note the full path of any CADImage-related DLL found
    Affected if A CADImage DLL file exists in the IrfanView plugins folder and its version is below 15.0.0.8
  2. Check 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.FileVersion (adjust path as needed)
    Affected if The displayed File Version is lower than 15.0.0.8 (e.g., 15.0.0.7, 14.x.x.x, etc.)
  3. Verify plugin is loaded by IrfanView
    Open IrfanView, go to Options > Properties/Settings > Plugins. Look for the CADImage plugin entry in the list of loaded plugins
    Affected if The CADImage plugin appears as Enabled or Loaded in the plugins list
  4. Confirm DWG file type handling is active
    In IrfanView, go to Options > File Types or check File > Open to see if .dwg files are listed as supported. Also check if double-clicking a DWG file opens it in IrfanView by default
    Affected if DWG files are listed as supported file types or open automatically in IrfanView, indicating the CADImage plugin is actively handling DWG parsing
  5. Check for multiple plugin instances
    Search the entire plugins directory for any additional CADImage DLL files or subdirectories containing the plugin, as older or alternate versions may be present
    Affected if Multiple CADImage DLL files exist with different versions, and any version is below 15.0.0.8

You are affected if the CADImage plugin DLL exists in IrfanView and its version is below 15.0.0.8, with DWG file handling enabled.
