This post is about a VirtualBox escape for the latest currently available version (VirtualBox 6.1.16 on Windows). The vulnerabilities were discovered and exploited by our team Sauercl0ud as part of the RealWorld CTF 2020/2021.
Many thanks to the organizers for hosting this great competition, especially to ChenNan for creating this challenge, M4x for always being helpful, answering our questions and sitting with us through the many demo attempts and of course all the people involved in writing the exploit.
