CVE-2025-7277
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 · uneditedIrfanView 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-26209.
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 confidenceMemory corruption vulnerability in IrfanView CADImage plugin's DWG file parser due to insufficient validation of user-supplied data during file parsing. Successful exploitation allows remote code execution in the context of the current process, but requires user interaction (opening a malicious DWG file).

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 checksWork through these to decide whether this CVE applies to you.
-
Locate CADImage plugin installationSearch for the CADImage plugin files (typically in the IrfanView plugins directory, commonly named 'cadimage.dll' or similar)Affected if CADImage plugin files are found on the system
-
Determine CADImage plugin versionRight-click the CADImage DLL file, select Properties, and check the File Version or Product Version fieldAffected if Version number is lower than 15.0.0.8 (e.g., 15.0.0.7, 14.x.x.x, etc.)
-
Check if DWG file association or preview is enabledVerify if DWG files are configured to open with IrfanView or if the CADImage plugin is used for thumbnail/preview generation of DWG filesAffected if DWG files can be opened or previewed through IrfanView using the CADImage plugin
You are affected if the CADImage plugin version is found to be lower than 15.0.0.8 and DWG files are processed through this plugin.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped15.0.0.8
Apply vendor patches for IrfanView CADImage plugin when available; until then, avoid opening untrusted DWG files and restrict use of the CADImage plugin to trusted sources.
Cadimage 15.0.0.8 or later
- Identify the CADImage plugin installation on the system
- Check the current version of the Cadimage plugin (likely found in IrfanView plugins directory or Add-ons folder)
- Navigate to the official Cadimage or IrfanView website to obtain the latest version
- Download and install Cadimage version 15.0.0.8 or later
- Verify the installed version matches the fixed release (15.0.0.8 or subsequent)
- Test DWG file opening functionality to ensure the plugin operates correctly after upgrade
