Lab: File path traversal, traversal sequences stripped with superfluous URL-decode

PRACTITIONER

This lab contains a file path traversal vulnerability in the display of product images.

The application blocks input containing path traversal sequences. It then performs a URL-decode of the input before using it.

To solve the lab, retrieve the contents of the /etc/passwd file.
