HTTP/2, as many of you already know, represents a significant revision of the HTTP protocol. It’s not just a novelty; it’s the backbone of modern web infrastructure. The likes of Apache, Nginx, and Varnish Cache have seamlessly integrated this protocol, making it a staple in web hosting, SaaS, and cloud services. Now, let’s dive into the heart of the matter. The HTTP/2 Rapid Reset Attack, referenced as CVE-2023-44487, is like a wolf in sheep’s clothing, hiding behind a minimal resource footprint to launch a massive Denial-of-Service (DoS) assault on unsuspecting websites. Websites lacking the necessary safeguards can find themselves helplessly overwhelmed, their precious server resources depleted.
