Description: When I was doing a pentest on a given target, I found this page. I think it’s vulnerable, but I’m not good at PHP, are you? Difficulty: Easy Recon When you visit the site for the challenge it brings you to a page titled “Printer”, with an input bar and a checkbox for a debug option. When I enter input and submit the form, it runs an HTTP GET request with echo ‘{my-input}’ as the value for the print parameter.
