CVE-2022-43609

Code execution via uninitialized STP parser pointer

Published Mar 29, 2023 · Updated Feb 14, 2025

Uninitialized pointer access in IronCAD 2022 allows context-dependent attackers to execute code through a crafted STP file. While parsing a VECTOR element, the STP parser accesses a pointer that was not properly initialized. Exploitation requires the targeted user to open the file or visit a malicious page, and successful code runs in the current process.
