From bug bounties to network pen tests, web applications are often the perimeter in many enterprise environments. Understanding how these applications work and interact with their backend is instrumental in being successful in your assessments. In this talk, I'll walk through a real exploit path (applications, names, and code changed to protect responsible disclosure) used in a personal bug bounty report, and more than one network penetration tests. We'll chain multiple vulnerabilities together, do quick win code analysis, and even use Local File Include (LFI) for more than just dumping /etc/passwd.
