Hey all,
A 'fixing the problem question'...
Outside of encrypting in SSL, how can variables being posted from the
browser back to the server be protected from prying eyes?
During previous pentests, I've seen variables being posted to a
webserver (IIS6.0 is one I remember this with) all hashed together.
I don't think that any special client-side software was used, it was
a function of the site....
Can anyone help in identifying what it was that I saw in operation? -
The only solution I can see is that it was the AspKeepSessionIDSecure
Metabase Property
(ref:http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/0d49cbc8-10e1-4fa8-ba61-c34e524a3ae6.mspx?mfr=true)
with the variables posted in with the sessionid?
Also, is this type of solution available in any other webserver?
Any help gratefully recieved...
Thanks..
The only way that you'd get this effect is with some kind of client
software. That software could be JavaScript (e.g. implementations of
MD5, or RSA, etc are available with a little searching), or a Java
applet, or ActiveX control.
But other than these mechanisms, there is no standard way of
encrypting/manipulating the form values before they are sent, that I
know of.
