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-26112.

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 arbitrary code execution by tricking a user into opening a specially crafted malicious DWG file.

MitigationApply the vendor-supplied patch or update to the CADImage Plugin when available; until then, avoid opening DWG files from untrusted sources and consider disabling the plugin in 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. Locate the CADImage plugin file
    Search for files named CADImage.dll or similar in the IrfanView installation directory, typically in a 'plugins' or 'plugins64' subfolder
    Affected if The CADImage plugin DLL file exists on the system
  2. Determine the plugin file version
    Right-click the CADImage DLL file, select Properties, and check the 'File version' or 'Product version' field in the Version tab
    Affected if The displayed version number is lower than 15.0.0.8 (for example, 15.0.0.7 or earlier)
  3. Confirm the plugin is loaded by IrfanView
    Open IrfanView, go to menu Image > Info, or check the plugin list in IrfanView's options or about section to verify the CADImage plugin is active
    Affected if IrfanView shows the CADImage plugin as loaded or enabled
  4. Check for DWG file associations
    Check if .dwg files are configured to open with IrfanView, or if users commonly open DWG files using IrfanView with the CADImage plugin
    Affected if IrfanView is set as the default handler for DWG files or users routinely open DWG files in IrfanView

The system is affected if the CADImage plugin DLL exists and its version is below 15.0.0.8, and the plugin is loaded or DWG files are opened with IrfanView.
