The article 'Practical HTTP Header Smuggling' delves into techniques related to the trust that browsers and servers place in HTTP headers. The authors focus on a phenomenon that can lead to vulnerabilities in web applications. HTTP Header Smuggling is a technique that can allow attackers to deceive either the server or the browser into misinterpreting HTTP headers, potentially leading to various attacks, such as data theft, bypassing security measures, or unauthorized access to systems. The article discusses several methods, including the use of differences in header interpretation by various systems and ways these attacks can be executed. Real-world examples of such attacks are provided, along with guidance on how to defend against them effectively. Lastly, it concludes with insights and recommendations for enhancing the security of systems reliant on the HTTP protocol.
