Proof of exploitability, or it didn't happen​

One of the most pervasive problems in cybersecurity is false positives. Organisations receive dozens of bogus vulnerability reports about their websites every day, and security teams burn hours trudging through the noise that automated scanners generate. Worse, CISOs can't prioritise what actually matters, because a false positive is so often hard to tell apart from a real finding.

How did we go so wrong? The ingredient missing from a false positive is proof of exploitability, and a rigorous one at that. Proof of exploitability, also called chain-of-attack proof, is one of the most important elements of any vulnerability report. Without it, a penetration testing report isn't worth your money. Reliable bug bounty platforms like HackerOne place heavy emphasis on proving a vulnerability is exploitable; without that ingredient, a report simply doesn't have a case.

Modern e-commerce platforms increasingly rely on distributed API architectures to power web and mobile applications. But as architectures shift toward interconnected microservices, the most dangerous bugs are found in the way data flows in the applications.

Recently, we conducted a structured security evaluation of a large-scale e-commerce API ecosystem. Rather than focusing on isolated vulnerabilities, the research aims to identify systemic patterns of failure across authentication flows, parameter handling, and microservice interactions.

Our mission: to see if we could break the business rules of a production environment using nothing but an interception proxy and a bit of creative curiosity.
