Lab: File path traversal, traversal sequences stripped non-recursively
This lab contains a file path traversal vulnerability in the display of product images.
The application strips path traversal sequences from the user-supplied filename before using it.
To solve the lab, retrieve the contents of the /etc/passwd file.
Use Burp Suite to intercept and modify a request that fetches a product image.
Modify the filename parameter, giving it the value: ....//....//....//etc/passwd
Observe that the response contains the contents of the /etc/passwd file.
