CVE-2024-23137

Code execution via uninitialized file-parser memory

Published Feb 22, 2024 · Updated Aug 28, 2025

Uninitialized memory access in ODXSW_DLL.dll in Autodesk AutoCAD 2021 through 2025 allows remote attackers to execute code via crafted files. The STP and SLDPRT parser accesses memory that was not properly initialized, allowing attacker-controlled file content to influence execution in the current process. Exploitation requires an end user to open or import a malicious file, and Autodesk states that only Windows versions of the listed products are affected.
