CVE-2023-49127

Code execution via PAR parser out-of-bounds read

Published Jan 9, 2024 · Updated Aug 27, 2025

Out-of-bounds read in Siemens Solid Edge SE2023 before V223.0 Update 10 allows attackers to execute code through a crafted PAR file. The PAR parser reads past the end of an allocated structure when it processes malformed file data. A local user must open the file; successful exploitation runs code in the current process, while failed attempts can crash the application.
