CVE-2024-45473

Code execution via WRL parser memory corruption

Published Oct 8, 2024 · Updated Dec 10, 2024

Memory corruption in Siemens Teamcenter Visualization and Tecnomatix Plant Simulation allows attackers to execute process-context code. The WRL parser corrupts memory while reading a specially crafted file, but Siemens has not disclosed the faulty parsing operation or code locus. Exploitation requires a user to open an untrusted WRL file and chaining with another vulnerability; successful exploitation runs code in the current process.
