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.
This article explores architectural issues within the Apache HTTP Server, highlighting several technical debts within Httpd, including 3 types of Confusion Attacks, 9 new vulnerabilities, 20 exploitation techniques, and over 30 case studies. The content includes, but is not limited to: 1. How a single ? can bypass Httpd's built-in access control and authentication. 2. How unsafe RewriteRules can escape the Web Root and access the entire filesystem. 3. How to leverage a piece of code from 1996 to transform an XSS into RCE.
We have also proved this attack works naturally on Microsoft Exchange Server. By leveraging the default activated Exchange Active Monitoring service, we can enter HealthMailbox's mailbox without passwords!
In order to leverage the vulnerabilities, we put part of efforts into review of Sandstorm's source codes, and tried to escape the sandbox to impact the whole server...
