And last but not least, we can send these requests to other tools such as Repeater and Intruder for modification and manipulation to induce vulnerabilities.īurp Suite reference documentation for Proxy: Link This can be useful to see the request attempt after clicking a button or performing another action on the website.Ĥ. We can also drop requests we don't want to be sent. We can modify our requests in-line similar to what you might see in a man-in-the-middle attack and then send them on.ģ. Requests will by default require our authorization to be sent.Ģ. By default, Burp will be set to 'intercept' our traffic. In task three, Gettin' Certified, we configured our web traffic to route through our instance of Burp Suite. #1 Which tool in Burp Suite can we use to perform a 'diff' on responses and other pieces of data?īasic diagram of how communications are relayed through a proxy - Wikipedia - Proxy Servers This feature, while not in the community edition of Burp Suite, is still a key facet of performing a web application test. Scanner - Automated web vulnerability scanner that can highlight areas of the application for further manual investigation or possible exploitation with another section of Burp. This is very similar to the Linux tool diff.Įxtender - Similar to adding mods to a game like Minecraft, Extender allows us to add components such as tool integrations, additional scan definitions, and more! These transforms vary from decoding/encoding to various bases or URL encoding.Ĭomparer - Comparer as you might have guessed is a tool we can use to compare different responses or other pieces of data such as site maps or proxy histories (awesome for access control issue testing). This is commonly used for testing session cookiesĭecoder - As the name suggests, Decoder is a tool that allows us to perform various transforms on pieces of data. Sequencer - Analyzes the 'randomness' present in parts of the web app which are intended to be unpredictable. Often used in a precursor step to fuzzing with the aforementioned Intruder Repeater - Allows us to 'repeat' requests that have previously been made with or without modification. Intruder - Incredibly powerful tool for everything from field fuzzing to credential stuffing and more We can also use this to effectively create a site map of the application we are testing. Target - How we set the scope of our project. Proxy - What allows us to funnel traffic through Burp Suite for further analysis Here's a quick overview of each section covered: Throughout this room, we'll be taking a look at these components of Burp Suite. Web application pentesting can be a messy affair but Burp has something for every step of the way. This ability to edit and resend the same request multiple times makes Repeater ideal for any kind of manual poking around at an endpoint, providing us with a nice Graphical User Interface (GUI) for writing the request payload and numerous views (including a rendering engine for a graphical view) of the response so that we can see the results of our handiwork in action.Now that we've set up Burp, let's take a look at everything it has to offer. Alternatively, we could craft requests by hand, much as we would from the CLI ( Command Line Interface), using a tool such as cURL to build and send requests. In layman’s terms, it means we can take a request captured in the Proxy, edit it, and send the same request repeatedly as many times as we wish. In short: Burp Suite Repeater allows us to craft and/or relay intercepted requests to a target at will. If you have not used Burp Suite before and have not completed the Burp Basics room, you may wish to do so now before continuing, as this room builds on the foundations covered there. Finally, we will encounter a series of examples, including a real-world, extra-mile exercise which we will use to consolidate the more theoretical aspects of the room. We will be covering how to use Repeater to manipulate and arbitrarily resend captured requests, as well as looking at some of the niftier options available in this awesome tool. This was part of TryHackMe JR Penetration Tester pathway. We covered the basics of the Repeater in Burp Suite and we presented an example using SQL injection scenario.
