The MadeYouReset Mayhem: A New HTTP/2 DoS Attack Threatening Web Security!
HTTP/2 implementations are vulnerable to a DoS attack called MadeYouReset, which bypasses server limits to flood systems with requests. This technique exploits mismatches in HTTP/2’s protocol, triggering server resets and causing resource exhaustion. As HTTP/2 is integral to web infrastructure, defending against attacks like MadeYouReset is crucial.
Hot Take:
In the ever-evolving world of cyber shenanigans, MadeYouReset is like the new kid on the block with an attitude and a knack for causing chaos. It’s the cyber equivalent of a bad hair day that just won’t quit — leaving servers with more resets than a reality TV show reunion!
Key Points:
- MadeYouReset is a new attack technique targeting multiple HTTP/2 implementations.
- It bypasses server limits, enabling thousands of requests to trigger denial-of-service (DoS) conditions.
- Assigned the generic CVE identifier CVE-2025-8671, affecting Apache Tomcat, F5 BIG-IP, and Netty.
- Exploits protocol violations using six specific primitives to induce server resets.
- Highlights the importance of securing HTTP/2 against nuanced, spec-compliant attacks.
