CVE-2023-24996

Code execution via SPP parser out-of-bounds write

Published Feb 14, 2023 · Updated Mar 19, 2025

Out-of-bounds write in Siemens Tecnomatix Plant Simulation before 2201.0006 allows attackers to execute code through a crafted SPP file. The SPP parser fails to validate user-supplied data before writing past the end of an allocated data structure. Exploitation requires a user to open the file or visit a malicious page, and resulting code runs in the current process context.
