LAB 9 - Reflected XSS into a JavaScript string with angle brackets HTML encoded

Initial instructions

This lab contains a reflected cross-site scripting vulnerability in the search query tracking functionality where angle brackets are encoded. The reflection occurs inside a JavaScript string. To solve this lab, perform a cross-site scripting attack that breaks out of the JavaScript string and calls the alert function.

To complete this lab I used the following XSS payload.

';alert(1);//'

So I entered this payload into the search bar and clicked Search.

And it will trigger the XSS successfully.

Congratulations, you solved the lab!
