CVE-2023-45601

Code execution via unchecked IGS buffer copy

Published Oct 10, 2023 · Updated Sep 19, 2024

Stack-based buffer overflow in Siemens Parasolid and Tecnomatix Plant Simulation allows remote attackers to execute code through a malicious IGS file. The IGS parser fails to validate user-controlled data length before copying it into a stack-based buffer. Exploitation requires a user to open the file, after which code runs in the current process and a failed attempt can crash it.
