CVE-2024-12670

Code execution via crafted DWFX heap overflow

Published Dec 17, 2024 · Updated Aug 26, 2025

Heap-based buffer overflow in Autodesk Navisworks 2025 before 2025.4 allows attackers to execute code through a crafted DWFX file. The DWFX parser writes beyond a heap buffer while processing attacker-controlled file content, but Autodesk has not identified the affected module or operation. Exploitation requires a user to open the file and can crash the application, expose process-accessible data, or run code in the current process.
