Re: Winnt/Win2k Vuln ?

["Enrique A. Compañ Gzz." <enrique () virtekweb net>]

Not exactly an issue....

because when you rename "autoexec.bat" to "www.google.com", what you
realy get is "www.google.com.BAT"
When you tipe "www.google.com" in the IE address bar, the file placed in
your desktop
get executed... (you can type the name of other files you have there,
without extension and they get
executed as well).

I think this is not a bug, but a non-smart feature, THAT CAN BE exploited.
for example, use any IE bug to create a file in your desktop, but name the
file to, say "www.yahoo.com.BAT" ...
When the user goes to www.yahoo.com.... bewm!!! the file gets executed.
