Frequently Asked Questions
1
What must an attacker do to exploit this issue?
An attacker needs to induce a user to load a crafted HTML page. The vulnerability can then potentially allow arbitrary code execution inside Chromium's sandbox.
2
Does exploitation require prior access or authentication?
No prior privileges are required. The supplied vector indicates network reachability with low attack complexity, but user interaction is required.
3
Is code execution outside the browser sandbox indicated?
No. The available description identifies potential arbitrary code execution inside the sandbox only; it does not state that a sandbox escape is possible.
