Code execution via JT stack buffer overflow
Published Jan 13, 2022 · Updated Aug 4, 2024
Stack-based buffer overflow in Bentley View 10.15.0.75 allows remote attackers to execute code by convincing a user to open a crafted JT file. The JT parser copies attacker-controlled data into a stack buffer without validating its length, allowing the copy to overrun the buffer. Exploitation requires user interaction through a malicious page or file and runs code with the privileges of the current Bentley View process.
