CVE-2023-38070

Code execution via unchecked WRL stack-buffer copy

Published Sep 12, 2023 · Updated Aug 2, 2024

Stack overflow in JT2Go, Teamcenter Visualization, and Tecnomatix Plant Simulation allows code execution through a crafted WRL file. The WRL parser copies user-supplied data into a stack-based buffer without first validating its length, allowing the copy to exceed the buffer. Exploitation requires a user to open the malicious file or visit attacker-controlled content, and resulting code runs in the current process.
