HTTP Challenge: Finding the Pattern

Use HTTP header NRP or X-NRP to explore a deterministic maze and discover the flag.

• Start at /maze.
• Send your NRP header on every request.
• Find the page containing marker <<<YOU FOUND ME>>>.
• Submit the flag to POST /submit using JSON.

Example

curl -H "NRP: 5025241234" http://progjar.web.id/maze

curl -X POST http://progjar.web.id/submit \
  -H "Content-Type: application/json" \
  -d '{"nrp":"5025241234","flag":"FLAG{...}"}'
