Hacking HTTP/2 - New attacks on the Internet’s Next Generation Foundation

Log in to save this to your schedule and see who's attending!

HTTP/2 is the emerging network protocol for the Internet, facilitating leaner and faster web browsing by introducing several new mechanisms which can be seen as a single transition layer for web traffic. The adoption of HTTP/2 is lightning fast, and even though only a year has passed since its publication, HTTP/2 is already supported by all significant players in the field including browsers, web servers and Content Delivery Networks.
In the presentation we will overview the HTTP/2 attack surface - stream multiplexing, flow control, HPACK compression and server push, with a focus on how the way HTTP/2 servers implement these mechanisms can make or break your security posture. We will continue with presenting new classes of vulnerabilities that have been introduced by the mechanisms used with HTTP/2, and explaining how these vulnerabilities can be used for mounting effective attacks against web servers like Apache, IIS, Ngnix, Jetty and nghttp. We will explain in details several serious zero-day vulnerabilities, such as CVE-2016-1546, CVE-2016-0150 and CVE-2016-1544, and end with discussing several approaches for mitigating attacks of these types.
Those attending this session will understand that:
1. As an emerging technology that introduces novel and flexible mechanisms, HTTP/2 also induces new risks.
2. HTTP/2 implementations are still not “security mature.” Therefore it is almost certain that scrutiny of HTTP/2 implementations will increase in coming years, resulting in the discovery of new vulnerabilities, exploits and security patches. With HTTP/2 gaining more popularity, this trend will intensify.
3. An effective security strategy for newly adopted technologies must rely on supplemental solutions rather than patching
