CVE-2023-49125

Code execution via XT parser out-of-bounds read

Published Feb 13, 2024 · Updated May 7, 2025

Out-of-bounds read in Siemens Parasolid and Solid Edge allows context-dependent attackers to execute code through a crafted XT file. The XT parser reads beyond the end of an allocated structure while processing malformed part data. Exploitation requires a user or host application to open the file, and successful code execution runs with the current process's privileges.
