Lab: Reflected XSS into a JavaScript string with angle brackets HTML encoded
Hello Friends,
I’m Rem01x And I’m Currently Preparing For The eWPTX Exam So I Will Be Walking Through All PortSwigger Labs And Make Sure To Make Writeups For All Of Them.
Let’s Start Now.
Assume that we have this website.

Please notice the search functionality.
let’s search for anything.

Notice that our search reflected to the page.
Now, let’s inspect the source code.

My name is reflected to a JavaScript code.
let’s try to breakout the code.
'-alert(1)-'

Now, press search.

As observed we got an alert.

Alright Let’s Go We Did It And Solve The Lab.
