Summary

  • In a late-night bug-hunting session, an ethical hacker based in India spotted an exposed origin IP at the country’s largest stockbroker, despite the fact the parent company used Cloudflare for protection.
  • The vulnerability could have allowed an attacker to bypass Cloudflare’s rate limits, fuzz without detection, brute force at full throttle and launch DDoS attacks.
  • After reporting the incident and having the vulnerability highlighted to the parent company, the ethical hacker was rewarded with a bounty payment of ₹XX,000 (approximately $312), for simply highlighting that the company had a security misconfiguration, and no actual harm was caused.
  • The tale serves to highlight to bug bounty hunters the importance of curiosity, reconnaissance and the fact that it is not always necessary to exploit a vulnerability to command a reward.
