CVE-2022-47936

Code execution via stack overflow in JT parser

Published Feb 14, 2023 · Updated Mar 20, 2025

Stack overflow in affected Siemens JT Open Toolkit, JT Utilities, and Parasolid releases allows local users to execute code via a JT file. The products' JT parsers overflow a stack buffer while processing specially crafted file data; Siemens has not disclosed the precise parser routine or malformed field. Exploitation requires a user to open the file, after which attacker-controlled code runs with the privileges of the current process or the application crashes.
