Business Logic Analysis

To find business logic vulnerabilities, you analyze multi-step workflows by mapping critical user roles, state machines, and trust boundaries to detect workflow manipulation and authorization bypasses. This requires understanding the application architecture and user interaction flows.

Trust boundaries in application security testing are the logical borders where data moves between trusted and untrusted application components. Identifying these boundaries is critical to uncover input validation weaknesses and authorization bypasses across user interaction flows.

You can test for authorization bypass in an e-commerce checkout process by systematically analyzing the underlying workflow logic to detect ways to bypass payment, manipulate prices, or abuse coupon codes across the application's state machine.

State machine flaws lead to workflow manipulation when the multi-step process fails to properly enforce sequence and state transitions. Modeling these state machines allows you to identify and exploit flaws in the intended application functionality.

Yes, detecting business logic flaws requires a deep understanding of application architecture and user interaction flows. You must map critical workflows and trust boundaries to find vulnerabilities rather than relying on traditional technical exploit scanning.
