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 Out-Of-Bounds Read 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 read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26130.

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

Out-of-bounds read vulnerability in IrfanView CADImage plugin's DWG file parser. The plugin fails to properly validate user-supplied data during DWG parsing, allowing reads past the end of allocated buffers. This memory corruption can be leveraged for remote code execution in the context of the current process.

MitigationApply vendor patches for the CADImage plugin immediately. Until then, refrain from opening untrusted DWG files and consider disabling or removing the CADImage plugin if DWG viewing is 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. Confirm IrfanView installation
    Check for IrfanView installation directory (typically C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView)
    Affected if IrfanView is installed on the system
  2. Locate CADImage plugin
    Search for CADImage plugin DLL (cadimage.dll) in IrfanView\Plugins or IrfanView\Plugins32 directory
    Affected if CADImage plugin DLL exists in the IrfanView plugins folder
  3. Check CADImage plugin version
    Right-click the CADImage DLL file, select Properties, and view the File Version or Product Version field
    Affected if The reported version is lower than 15.0.0.8 (e.g., 15.0.0.7, 14.x, etc.)
  4. Verify plugin is loaded by IrfanView
    Open IrfanView, go to menu: Image > Properties, or check menu options for CAD/DWG file support under File > Open
    Affected if DWG file types are recognized or the CADImage plugin is listed as active in IrfanView's plugin information (Menu > Help > Installed plugins)
  5. Check for recent DWG file handling
    Review recent file access logs, Windows Prefetch, or examine the IrfanView recent files list for .dwg file opens
    Affected if Untrusted or unknown DWG files have been opened using IrfanView with the CADImage plugin

The system is affected if IrfanView with the Cadsofttools CADImage plugin (version below 15.0.0.8) is installed and the plugin is enabled to handle DWG files.

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

Apply vendor patches for the CADImage plugin immediately. Until then, refrain from opening untrusted DWG files and consider disabling or removing the CADImage plugin if DWG viewing is not required.

Recommended fix High confidence

Cadimage 15.0.0.8 or later

  1. Identify the current version of the Cadimage plugin installed in IrfanView by checking the plugin properties or version information
  2. Navigate to the official Cadimage vendor website or trusted distribution channel to obtain the latest version
