Tryhackme – Burpsuite: The Basics

In this walk through, we will be going through the Burp suite room from Tryhackme. This room covers the basics of Burpsuite, which is one of the most famous tool that is used in web application pentesting. Having this in your arsenal is a must to go further in your pentesting journey. So, let’s get started.

Task 13 - Site Map and Issue Definitions

Task 14 – Example Attack

We will start by taking a look at the support form at

support contact box

In a real-world web app pentest, we would test this for a variety of things: one of which would be Cross-Site Scripting (or XSS). If you have not yet encountered XSS, it can be thought of as injecting a client-side script (usually in Javascript) into a webpage in such a way that it executes. There are various kinds of XSS — the type that we are using here is referred to as “Reflected” XSS as it only affects the person making the web request.

Try typing: <script>alert("Succ3ssful XSS")</script>, into the “Contact Email” field. You should find that there is a client-side filter in place which prevents you from adding any special characters that aren’t allowed in email addresses:

contact box

Fortunately for us, client-side filters are absurdly easy to bypass. There are a variety of ways we could disable the script or just prevent it from loading in the first place.

Let’s focus on simply bypassing the filter for now.

First, make sure that your Burp Proxy is active and that the intercept is on.

Now, enter some legitimate data into the support form. For example: “[email protected]” as an email address, and “Test Attack” as a query.

Submit the form — the request should be intercepted by the proxy.

With the request captured in the proxy, we can now change the email field to be our very simple payload from above: <script>alert("Succ3ssful XSS")</script>. After pasting in the payload, we need to select it, then URL encode it with the Ctrl + U shortcut to make it safe to send. This process is shown in the GIF below:

Finally, press the “Forward” button to send the request.

You should find that you get an alert box from the site indicating a successful XSS attack!

So that was it. We started with the basics from installation to covering various options in the tool. Going further, we understand how to configure the Foxyproxy plugin for burpsuite. Next, we learned how to capture request and how to manipulate it as per our requirement. With this in mind, try to play with some web apps and get more familiar with this tool. Till then, i will take your leave, but remember to “Keep Hacking”.
