Enumerate Windows Users In JS

ha.ckers.org web application security lab

Sergey Vzloman's proof of concept enumerates local Windows account names from JavaScript by probing Firefox resource:// URLs; the demo tries four accounts and is deliberately noisy. Dan Veditz notes the resource:// issue is fixed in Firefox 2.0.0.4 and 1.5.0.12, but older builds stay exposed, and a few hundred name guesses run quickly.
