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-26203.

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

Memory corruption vulnerability in IrfanView CADImage Plugin's DWG file parser due to insufficient validation of user-supplied data during file parsing. Successful exploitation allows arbitrary code execution in the context of the current process.

MitigationUpdate CADImage Plugin to vendor-patched version; avoid opening untrusted DWG files until patch is applied.

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. Verify IrfanView installation
    Check if IrfanView is installed on the system by looking for the IrfanView executable (typically in Program Files or Program Files (x86)).
    Affected if IrfanView is not installed - the plugin cannot be loaded.
  2. Locate CADImage plugin
    Look for CADImage plugin files in IrfanView's plugins directory (typically \Program Files\IrfanView\Plugins or similar). The plugin is usually named CADImage.dll or similar CADImage component.
    Affected if CADImage plugin file is not present - the vulnerability cannot be triggered.
  3. Determine CADImage plugin version
    Right-click the CADImage DLL file, select Properties, and check the File Version tab. Compare this version number to 15.0.0.8.
    Affected if The installed version is lower than 15.0.0.8 - the system is vulnerable.
  4. Confirm plugin handles DWG files
    Check if IrfanView is configured to open DWG files, or if the CADImage plugin is registered as a handler for DWG file associations.
    Affected if DWG file association or preview is enabled - the vulnerability can be triggered by opening a malicious DWG file.

The environment is affected if IrfanView with CADImage plugin version below 15.0.0.8 is installed and the plugin is available to process DWG files.

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

Update CADImage Plugin to vendor-patched version; avoid opening untrusted DWG files until patch is applied.

Recommended fix Moderate confidence

Cadimage version 15.0.0.8 or later

  1. 1. Close any running instances of IrfanView or applications using the Cadimage plugin
  2. 2. Obtain the latest version of Cadimage (version 15.0.0.8 or later) from the official vendor or authorized distribution channel
  3. 3. Uninstall the current Cadimage plugin installation
  4. 4. Install the updated Cadimage version 15.0.0.8 or newer
  5. 5. Restart IrfanView and verify the plugin loads correctly
  6. 6. Avoid opening untrusted DWG files from unknown sources to mitigate remaining risks
