Lab: File path traversal, traversal sequences blocked with absolute path bypass in Malayalam

Описание

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

The application blocks traversal sequences but treats the supplied filename as being relative to a default working directory.

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


Solution
1. Use Burp Suite to intercept and modify a request that fetches a product image.
2. Modify the filename parameter, giving it the value /etc/passwd.
3.Observe that the response contains the contents of the /etc/passwd file.
