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-26095.

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 (Drawing) files, leading to memory corruption. An attacker can exploit this by tricking a user into opening a malicious DWG file, potentially allowing arbitrary code execution in the context of the current process.

MitigationApply the latest vendor patch for the IrfanView CADImage plugin when available. Until then, avoid opening DWG files from untrusted sources and consider disabling the CADImage 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 installation
    Search for cadimage.dll or CADImage plugin files in the IrfanView plugins directory (typically C:\Program Files\IrfanView\Plugins or C:\Program Files (x86)\IrfanView\Plugins)
    Affected if The CADImage plugin file exists on the system
  2. Identify the CADImage plugin version
    Right-click the cadimage.dll file, select Properties, then navigate to the Details tab to view the File Version. Alternatively, use a tool like ExifTool or view version info via PowerShell: (Get-Item 'C:\Program Files\IrfanView\Plugins\cadimage.dll').VersionInfo
    Affected if The reported version is lower than 15.0.0.8
  3. Verify DWG file association with IrfanView
    Check if .dwg file extension is associated with IrfanView by opening IrfanView, going to Properties (press F5) or checking Windows file association settings for .dwg files
    Affected if IrfanView is configured as the default handler for DWG files or has the CADImage plugin enabled for DWG parsing
  4. Confirm the plugin is loaded
    Open IrfanView and attempt to open a DWG file, or check the plugin information via IrfanView's Properties window (F5) to see if CADImage appears in the loaded plugins list
    Affected if The CADImage plugin loads when IrfanView opens DWG files

A user is affected if the IrfanView CADImage plugin version is below 15.0.0.8 and the plugin is present and enabled for handling DWG files on the system.
