The paper introduces the problem we’ve been facing more and more while testing complex web applications, and shows two working solutions. Burp Suite is known by most and used by many professionals in this field, so its GUI-based features are presented first. But as Burp is far from a one-size-fits-all perfect solution, an alternative is shown combining mitmproxy and commix – a dynamic duo that can not only detect but also exploit the issues. To make things easier to demonstrate (and possibly replicate and improve by readers), an intentionally vulnerable web application was developed that (unlike the aforementioned complex apps) requires minimal effort to deploy, lowering the bar for developing tools that can be used later in enterprise environment.
