There is a bug in Netscape Communicator 4.51,4.5/Win95, 4.08/WinNT
(probably others?),
which allows sniffing URLs from another window.
The exploit uses the ability to execute JavaScript code from specially
designed
URLs in the javascript console window, when an error is deliberately
invoked.

Demonstration and source is available at:
http://www.nat.bg/~joro/b11.html

(The exploit does not work if you are behind some versions of a squid
proxy.
If you do not see your URL in a message box, try reloading the main
page).

Workaround: Disable JavaScript.

Regards,
Georgi Guninski
