CVE-2025-40809

Code execution via out-of-bounds PRT write

Published Oct 14, 2025 · Updated Oct 14, 2025

Out-of-bounds write in Siemens Solid Edge SE2024 and SE2025 allows attackers to execute code by convincing a user to open a crafted PRT file. The PRT parser performs an out-of-bounds memory write while processing attacker-controlled file data; Siemens does not identify the faulty routine. Successful exploitation requires user interaction and runs code in the current process; malformed input can instead crash the application.
