Stealing idea from David Christiansen’s Blog
If you find yourself ( or Tester 😉 ) typing asdf over and over again as you test data entry on
a web-app, do this instead:
Paste it in every field.
If an alert pops up OR the field gets saved and then gets rendered without the
script tags, you’ve found a cross-site scripting vulnerability.
The minute you find one, your brain will power up and you’ll find more energy for testing that data input.
