HOW RECON HELPED ME TO GET A STORED XSS!

Reconnaissance in bug bounty is very important!

INTRODUCTION

Hey everyone! I hope you all are doing good. In this article i am going to show you that how i was able to find a store cross site scripting vulnerability by diving deep into the target.

Before we jump into this article, if you guys are not familiar with cross site scripting vulnerability then you can check it out here.

First of all, let us talk about what is recon?

In simple terms, it is a way to gather more and more information about your target. Let’s take a simple example:

Suppose you are a person A and you have a crush on person B. So normally you will stalk her social media profiles to get more information about what she likes, what she is doing today. You are probably doing this so that you can get to know more about her. This is what reconnaissance is all about.

I hope you understood what reconnaissance is from the above example. But unlike in the example above, your target is going to be a website or an organization.

STORY OF STORED XSS:

I was hunting on private program that offers a coding platform to its users.(We’’ call it Vulnerable Organization). The first thing that i started to do is visit crunchbase to get more acquisitions of the company. I found that the company has 2 acquisitions(Lets say Org1 and Org2). There, i search Org1 on crunchbase and found that this company also has one acquisition. (Let’s say Org3). After this, i started manual testing on the Org3’s website(let’s say testing.com). There i found an input field that is asking for name. I passed the value below and click on Go:

<img src=x onerror=alert(1)>

After that, i got the following result:

Alert popped up!😁😁😁😁

I reported this vulnerability to the respected company and they offered me company’s swag😇😎
