Analysis to Remote Root 0day in a SSL-VPN Appliance

Delve into a comprehensive analysis of remote root vulnerabilities in SSL-VPN appliances through this Hack In The Box Security Conference presentation. Explore the internals of the F5 FirePass SSL-VPN Appliance, uncovering hidden vulnerabilities despite existing security protections. Follow the journey from reverse engineering to binary planting, decrypting file systems, and examining the environment. Discover how web vulnerabilities, format string vulnerabilities, and persistence lead to overcoming multiple limitations and protections, ultimately gaining a remote unauthenticated root shell. Learn about the responsible disclosure process and the exemplary vendor response from F5. Gain insights into the misconceptions surrounding "security appliances" and the potential impact on Fortune 500 companies. Benefit from the expertise of Israeli security researcher Tal Zeltzer as he shares his findings, research methods, and tools developed during this in-depth investigation.
