CVE-2022-41851

Code execution via uninitialized JT parser pointer

Published Oct 11, 2022 · Updated May 20, 2025

Uninitialized pointer access in Siemens JTTK and Simcenter Femap allows remote attackers to execute code through a crafted JT file. The JT file parser accesses a pointer without properly initializing it, which can crash the application or redirect execution within its process. Exploitation requires a user to open a malicious JT file; affected releases are JTTK before 11.1.1.0 and Femap 2022.1 before 2022.1.3 or 2022.2 before 2022.2.2.
