The research unveils a new attack surface in Windows by exploiting Best-Fit, an internal charset conversion feature. Through our work, we successfully transformed this feature into several practical attacks, including Path Traversal, Argument Injection, and even RCE, affecting numerous well-known applications!
This research continues to explore the attack surface of Kernel Streaming, delving into newly discovered vulnerabilities within another feature of Kernel Streaming and demonstrating how to leverage this bug class to successfully attack Windows 11. This topic was also presented at HEXACON 2024.
This research will discuss an overlooked attack surface that allowed us to find more than ten vulnerabilities within two months. Additionally, we will delve into a proxy-based logical vulnerability type that allows us to bypass most validations, enabling us to successfully exploit Windows 11 in Pwn2Own Vancouver 2024.
