CVE-2024-45476

Application crash via WRL parser null dereference

Published Oct 8, 2024 · Updated Dec 10, 2024

Null pointer dereference in Siemens Teamcenter Visualization and Tecnomatix Plant Simulation allows attackers to crash the application. The WRL parser dereferences a null pointer while reading a specially crafted file, terminating the current process instead of rejecting the malformed content. Exploitation requires a user to open an untrusted local WRL file; the reported impact is a recoverable application crash, not code execution or data access.
