Episode 70 — Web Attack Surface: Inputs, Auth, Sessions

This episode builds a structured understanding of web attack surface by focusing on inputs, identity flows, session handling, and authorization boundaries, which together explain most real-world web failures. You’ll learn how user-controlled inputs appear in parameters, headers, forms, and uploads, how authentication flows include login, MFA, reset, and SSO entry points, and how sessions and tokens represent continuing trust that can be stolen or mismanaged. We’ll cover authorization as the server-side logic that determines what a user can access or modify, including object-level and function-level boundaries, and why access control failures often matter more than flashy injection in practical impact. You’ll practice mapping a web feature end to end from public entry to protected actions, identifying where safe validation should focus first and how to avoid common traps like testing only one role or missing business-logic workflows. By the end, you’ll be able to interpret scenario clues about web behavior, select the best next test action, and describe findings in language that ties the weakness to user impact and clear remediation steps.
