24.1 Lab: HTTP request smuggling, confirming a CL.TE vulnerability via differential responses | 2024
A Simple writeup is posted on Medium - / cyberw1ng
Description - Portswigger Lab
This lab involves a front-end and back-end server, and the front-end server doesn't support chunked encoding.
To solve the lab, smuggle a request to the back-end server, so that a subsequent request for / (the web root) triggers a 404 Not Found response.
