Something very boring happening in a web application penetration test is to reach out URLs that are not referenced in other pages.
You may think about APIs or old legacy code that is online for mistake… it’s not so uncommon to miss something in the scanning perimeter since it can’t be reached by your favourite crawler.
A clever solution is to ask developers who eventually write the code. We will ask them for their web.xml file.
Don’t bother my please.
