Unveiling the Core Concepts

Request Smuggling: The crux of HTTP smuggling lies in crafting requests that exploit differences in the interpretation of these requests between front-end and back-end servers. This manipulation can result in the smuggling of unauthorized content.

Front-End and Back-End Servers: The front-end server, often a proxy or load balancer, is the first point of contact for incoming requests. The back-end server, on the other hand, is the web server responsible for processing these requests. Discrepancies in how these servers parse HTTP headers and handle connection persistence provide the perfect vulnerable environment for HTTP smuggling attacks.

Advanced Phishing Tactics to Look Out For
