Fortune 100 Cyber Oops: Misconfigured WAFs Leaving Back-End Servers Vulnerable!

Many organizations using Web application firewall services from CDN providers are unknowingly exposing their back-end servers to direct Internet attacks due to a common configuration error. Shockingly, this affects nearly 40% of Fortune 100 companies, including big names like Chase and Visa, leaving them vulnerable to a host of cyber threats.

Hot Take:

Who needs hackers when you have misconfigured firewalls? Fortune 100 companies are accidentally playing a game of ‘peek-a-boo’ with their back-end servers, leaving them wide open for the world (and cybercriminals) to see. It’s like leaving your front door open with a sign that says, ‘Not home, but feel free to come in!’

Key Points:

  • Fortune 100 companies are unintentionally exposing their servers due to common WAF configuration errors.
  • Zafran researchers identified 2,028 vulnerable domains from 135 companies.
  • Misconfiguration responsibility lies with both CDN/WAF customers and providers.
  • Best practices, like IP filtering and mutual TLS authentication, are often not implemented.
  • CT logs make discovering vulnerable servers much easier for attackers.
