Task: read a flag from an internal MJPEG camera stream not accessible from outside, using a Playwright Firefox bot with 75s timeout. Solution: PHP session file injection for XSS, then DNS rebinding via rbndr.us with iptables TCP RST blocking to force DNS re-resolution after 60s Firefox cache expiry, exfiltrate MJPEG frame via shared session.
