Summary

  • Ethical hacker Ehteshamul Haq has explained how he was able to delete a user’s entire account from target.
  • Haq discovered that the login endpoint on the target site allowed for unlimited login attempts, meaning he could use a brute-force attack to gain entry to any account.
  • From there, he discovered that the account deletion function was insecure, allowing him to delete any account on the site without any kind of verification.
  • The vulnerability has now been fixed, but Haq said the discovery highlighted how even simple vulnerabilities can lead to catastrophic impact if left unchecked.
  • He said that the attack could have been mitigated by implementing rate limiting and further validation upon account deletion.
