Browser-Powered Desync Attacks: A New Frontier in HTTP Request Smuggling

Security

Browser-powered desync attacks: a new type of HTTP request smuggling vulnerability that allows attackers to send arbitrary requests and manipulate the browser's request queue, compromising web servers and applications.

Key takeaways

Browser-powered desync attacks can be used to compromise web servers and applications.
The attacks can be triggered by manipulating HTTP headers and timing, allowing an attacker to send arbitrary requests and manipulate the browser’s request queue.
The attacks can be used to bypass certain security measures, such as HSTS headers and Content Security Policy.
Browser-powered desync attacks are considered to be highly effective and can be used to target both HTTP/1 and HTTP/2 connections.
The attacks can be used to steal user credentials, inject malware, and perform other malicious activities.
Browser-powered desync attacks have been demonstrated on several major web applications, including Amazon and Pulse Secure.
The attacks are considered to be highly exploitable and can be used by attackers to compromise sensitive information.
The researcher has released a proof-of-concept tool that demonstrates the feasibility of the attack and has identified several vulnerabilities that can be exploited.
The researcher is releasing the tool to the public and is urging web developers to prioritize patching the identified vulnerabilities.
The attacks are considered to be highly significant and can have serious consequences for web users and applications.
The attacks are considered to be easy to execute and can be performed by attackers without extensive technical expertise.
The attacks can be used to compromise sensitive information and can have serious consequences for web users and applications.
