CVE-2025-7237

Code execution via unvalidated DWG parsing

Published Jul 21, 2025 · Updated Jul 22, 2025

Memory corruption in the IrfanView CADImage Plugin in IrfanView 4.70.0.0 allows remote attackers to execute code via a crafted DWG file. The DWG parser does not properly validate user-supplied file data before processing it, producing memory corruption in the current process. Exploitation requires the target to open the malicious file or visit a page that supplies it, and successful exploitation runs code with the viewer's privileges.
