CVE-2023-41139

Code execution via unvalidated STP pointer dereference

Published Nov 23, 2023 · Updated Aug 2, 2024

Untrusted pointer dereference in Autodesk AutoCAD 2021 through 2024 allows remote attackers to execute code via a crafted STP file. The STP parser uses a user-supplied value as a pointer without validating it before dereference, causing memory access through an attacker-controlled address. Exploitation requires the target to visit a malicious page or open the file; successful exploitation runs code in the current process.
