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-26381.

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 for IrfanView contains a memory corruption vulnerability in its DWG file parser. The flaw stems from insufficient validation of user-supplied data during DWG parsing, allowing attackers to overwrite memory and execute arbitrary code in the context of the current process.

MitigationAvoid opening DWG files from untrusted sources; update the CADImage plugin to the latest patched version once available; consider using antivirus scanning on untrusted files.

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
    Check the IrfanView Plugins folder (typically C:\Program Files\IrfanView\Plugins\ or C:\Program Files (x86)\IrfanView\Plugins\) for a DLL related to CADImage, CAD, or DWG support (commonly CADImage.dll or similar).
    Affected if The CADImage plugin DLL exists in the IrfanView plugins directory.
  2. Check the installed version of the CADImage plugin
    Right-click the CADImage DLL file, select Properties, and view the Version tab to find the Product Version or File Version information.
    Affected if The version number shown is less than 15.0.0.8 (for example, 15.0.0.7 or earlier), or no version information is displayed.
  3. Verify DWG file association or support is active
    In IrfanView, go to Options > Properties/Settings > Plugins to confirm the CADImage plugin is loaded and enabled. Alternatively, attempt to open a DWG file or check File > Open for .dwg file type visibility.
    Affected if The plugin shows as loaded/enabled in the plugins list or .dwg files are recognized as openable.
  4. Identify if untrusted DWG files have been opened recently
    Review recent file access in IrfanView, check the application's recent files list, or inspect the file system for recently opened .dwg files from unknown or external sources.
    Affected if DWG files from untrusted or unknown sources have been opened with IrfanView.

If the CADImage plugin is installed, shows a version below 15.0.0.8, is enabled in IrfanView, and has been used to open DWG files, the environment is affected by this vulnerability.
