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-26386.

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 lacks proper input validation when parsing DWG (Drawing) files. The vulnerability stems from insufficient validation of user-supplied data during the DWG file parsing process, leading to memory corruption. Successful exploitation allows an attacker to execute arbitrary code in the context of the current process by tricking a user into opening a malicious DWG file.

MitigationUsers should avoid opening untrusted or unverified DWG files until a patch is available from the vendor. Organizations should deploy endpoint detection and monitoring solutions and consider restricting file handling permissions for the affected plugin.

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. Common installation paths: C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView. Look for irfanview.exe
    Affected if IrfanView is present on the system
  2. Locate CADImage plugin
    Check for CADImage plugin files in the IrfanView plugins directory. Typically found at C:\Program Files\IrfanView\Plugins\ or C:\Program Files (x86)\IrfanView\Plugins\. Look for files named CadImage.dll or similar CADImage-related DLLs
    Affected if CADImage plugin DLL exists in the IrfanView plugins folder
  3. Determine CADImage plugin version
    Right-click the CADImage DLL file, select Properties, and check the File Version tab. Alternatively, use PowerShell: (Get-Item 'C:\Program Files\IrfanView\Plugins\CadImage.dll').VersionInfo | Select-Object FileVersion
    Affected if The reported version number is less than 15.0.0.8 (e.g., 15.0.0.7, 14.x.x.x, etc.)
  4. Confirm DWG file association or capability
    Check if the CADImage plugin handles DWG files by opening IrfanView, going to Options > Plugins Settings, or by attempting to open a DWG file through IrfanView to see if CADImage is invoked
    Affected if IrfanView uses the CADImage plugin to render or preview DWG files, enabling the vulnerable code path

The environment is affected if IrfanView with CADImage plugin version below 15.0.0.8 is installed and the plugin is capable of processing DWG files.

dbcve · scoped
Upgrade available Upgrade to 15.0.0.8 or later
Fixed in 15.0.0.8
Interim mitigation

Users should avoid opening untrusted or unverified DWG files until a patch is available from the vendor. Organizations should deploy endpoint detection and monitoring solutions and consider restricting file handling permissions for the affected plugin.

Recommended fix High confidence

Cadimage 15.0.0.8 or later

  1. Identify all systems with the Cadimage plugin installed for IrfanView
  2. Obtain Cadimage version 15.0.0.8 or later from the official Cadimage vendor
  3. Uninstall the current Cadimage plugin version
  4. Install the updated Cadimage version 15.0.0.8 or later
  5. Restart IrfanView if it was running during the update
  6. Verify the installed version is 15.0.0.8 or later
