Code execution via unchecked OBJ buffer copy
Published Mar 29, 2023 · Updated Feb 18, 2025
Stack-based buffer overflow in Bentley Systems MicroStation 10.16.02.034 allows remote attackers to execute code via a crafted OBJ file. The OBJ parser copies attacker-controlled data into a fixed-length stack buffer without first validating the supplied length. Exploitation requires a user to open the file or visit a page that causes it to open, and code runs with the current process privileges.
