XSS is all about practice. It requires a lot of time to print in the mind all vectors, payloads and tricks at our disposal. There are lots of XSS cases, each one requiring a different approach and construct to pop the alert box.
Thinking on that and following the previous XSS Test Page released with the blog post “The 7 Main XSS Cases Everyone Should Know“, a new set of XSS exercises was built to help with that practice both for beginners and advanced XSS testers, since the same XSS cases are useful to test and build new XSS vectors.
This new “workout” can be found in our XSS GYM.
