Off-Path TCP Exploits of the Challenge ACK Global Rate Limit
In this paper, we report a subtle yet serious side channel vulnerability (CVE-2016-5696) introduced in a recent transmission control protocol (TCP) specification. The specification is faithfully implemented in Linux kernel version 3.6 (from 2012) and beyond, and affects a wide range of devices and hosts. In a nutshell, the vulnerability allows a blind offpath attacker to infer if any two arbitr...

In this paper, we report a subtle yet serious side channel vulnerability (CVE-2016-5696) introduced in a recent TCP specification. The specification is faithfully implemented in Linux kernel version 3.6 (from 2012) and beyond, and affects a wide range of devices and hosts. In a nutshell, the vulnerability allows a blind off-path attacker to infer if any two arbitrary hosts on the Internet are c...
متن کاملA Off-Path TCP Injection Attacks
TCP is the main transport protocol over the Internet, ensuring reliable and efficient connections. TCP is trivially vulnerable to man-in-the-middle (MitM) attackers; they can intercept, modify and inject TCP traffic [Joncheray 1995]. Despite significant possible threats, a common assumption is that MitM capabilities are difficult to obtain; this assumption is demonstrated by OWASP’s list of top...
متن کاملTCP Ack Storm DoS Attacks
We present Ack-storm DoS attacks, a new family of DoS attacks exploiting a subtle design flaw in the core TCP specifications. The attacks can be launched by a very weak MitM attacker, which can only eavesdrop occasionally and spoof packets (a Weakling in the Middle (WitM)). The attacks can reach theoretically unlimited amplification; we measured amplification of over 400,000 against popular web...
متن کاملResilience of Deployed TCP to Blind Off-Path Attacks
As part of TCP’s steady evolution, recent standards have recommended mechanisms to protect against weaknesses in TCP. But adoption, configuration, and deployment of TCP improvements can be slow. In this work, we consider the resilience of deployed TCP implementations to blind in-window attacks, where an off-path adversary disrupts an established connection by sending a packet that the victim be...
