# Apache Proxy Paradox CVE-2021-40438

## Summary

Sometimes the biggest breaches start with the simplest blind spots. During a recent engagement, we were handed what looked like an ordinary corporate portal, with a clean interface, a standard login page, and nothing flashy. At first glance, it felt routine. Just another web app sitting quietly on the internet.
