CVE-2024-7675

Arbitrary code execution via DWF use-after-free

Published Sep 30, 2024 · Updated Aug 26, 2025

Use-after-free in w3dtk.dll in Autodesk Navisworks 2022 through 2025 allows local users to execute code via a crafted DWF file. The parser accesses an object after its release while processing attacker-controlled DWF data; Autodesk has not disclosed the specific lifetime error. Exploitation requires user interaction to open or import the file and can crash the current process or run code with that process's privileges.
