Shreeraj's security blog: Password extraction from Ajax/DOM/HTML5 routine

shreeraj · shreeraj.blogspot.com

A short note on sloppy Ajax login code: variables such as the crafted request URL are declared without scope and stay global on the DOM for the life of the page. Given a DOM XSS foothold, iterating over window and printing every string property recovers login.do?user=foo&pwd=foobar, leaking the typed username and password.
