Disabling browser Javascript breaks application

Question

Hi. I am trying to bypass user validation for XSS. The validation is on the client-side and I tried disabling the javascript on the browser but this breaks the application. What do I do?

Answer 1

This usually happens if the javascript contains more functions than just the validation. In such cases, the way to handle it is by using proxy interceptors. You can use BurpSuite for this. First, give valid inputs and capture the requests in Burp. This ensures that the validation is done. After that, modify the value in Burp and forward the request to the server.
