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-26400.

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 for IrfanView contains a memory corruption vulnerability in its DWG file parsing logic. The flaw stems from insufficient validation of user-supplied data during DWG file processing, which can lead to controlled memory corruption and allow an attacker to execute arbitrary code within the context of the running process.

MitigationUpdate the IrfanView CADImage plugin to the latest patched version when available. Until then, avoid opening untrusted DWG files and disable the CADImage plugin if 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 the IrfanView installation directory for a DLL related to CADImage or DWG handling (typically in a 'Plugins' subfolder). Common names include CADImage.dll or similar. Use: dir /s /b "C:\Program Files\IrfanView\*CAD*" or locate it manually in the Plugins folder.
    Affected if The CADImage plugin DLL exists in the IrfanView plugins directory.
  2. Determine the installed CADImage plugin version
    Right-click the located CADImage DLL file, select Properties, then view the Details tab to find the File Version. Alternatively, use PowerShell: (Get-Item "path\to\CADImage.dll").VersionInfo.FileVersion.
    Affected if The displayed version is lower than 15.0.0.8 (for example, 15.0.0.7 or earlier).
  3. Verify the plugin loads in IrfanView
    Open IrfanView, go to menu: Image > Properties, or check Help > About Plugins. Look for CADImage or DWG in the loaded plugins list. You can also open a DWG file to see if IrfanView attempts to process it.
    Affected if CADImage plugin appears in the loaded plugins list and IrfanView can open DWG files.
  4. Confirm DWG file associations are active
    Check if .dwg file associations point to IrfanView, or if IrfanView is configured to handle DWG files through the CADImage plugin. Attempt to open a DWG file with IrfanView or check IrfanView's file open dialog for DWG support.
    Affected if IrfanView is configured to open DWG files using the CADImage plugin.

You are affected if the CADImage plugin DLL is present in IrfanView, loads successfully, and its version is lower than 15.0.0.8.

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

Update the IrfanView CADImage plugin to the latest patched version when available. Until then, avoid opening untrusted DWG files and disable the CADImage plugin if not required.

Recommended fix Moderate confidence

Cadimage version 15.0.0.8 or later

  1. 1. Identify all systems with Cadimage plugin versions prior to 15.0.0.8 installed.
  2. 2. Verify that the IrfanView CADImage plugin is installed and note its current version.
  3. 3. Obtain the fixed Cadimage version 15.0.0.8 or later from the official vendor (Cadimage/Logic or IrfanView distribution channels).
  4. 4. Uninstall the vulnerable Cadimage plugin version from affected systems.
  5. 5. Install the updated Cadimage version 15.0.0.8 or newer.
  6. 6. Verify the installed version matches or exceeds 15.0.0.8.
  7. 7. Test DWG file parsing functionality to ensure the update does not break legitimate workflows.
Caveat Unknown - review vendor release notes for any functional changes in version 15.0.0.8
