Exploiting business logic error vulnerabilities

It's no secret that complexity is the biggest rival of safe applications. As web apps become more sophisticated, they create countless opportunities for logic flaws to arise. Unlike technical vulnerabilities that can be easily automated, business logic errors emerge from the gap between how developers expect systems to behave and how attackers can manipulate them. In this article, we explore how to identify and exploit business logic flaws to bypass restrictions, escalate privileges, and introdu…
