Windows is an operating system with a long history, which also means that it has a lot of codes that have been used for many years. These codes may not be fully considered for their security when they are written. I found an attack surface called rasman (remote access connection manager) that has been hidden for a long time, at least since the windows nt4 version has existed.

In this talk, I will introduce the architecture of this module in detail, and introduce how I can find 10+ vulnerabilities in this module in a short period of time. Finally, I will introduce two vulnerabilities which bypasses all current mitigations, and won the windows EOP project in Tianfu cup 2021
