CVE-2023-24561

Code execution via uninitialized PAR parser pointer

Published Feb 14, 2023 · Updated Mar 20, 2025

Uninitialized pointer access in Siemens Solid Edge allows attackers to execute code when a user opens a crafted PAR file. The PAR parser accesses an uninitialized pointer while processing attacker-controlled file contents, corrupting process memory. Exploitation requires local delivery of a malicious PAR file and user interaction to open it; successful code runs with the current process's privileges.
