Penetration Testing: Password HTML form bruteforce

Password HTML form bruteforce

('binary' encoding is not supported, stored as-is) Hi there,

I am currently involved in a pen test on a website
which is using formbased authentication.

I figured out that a account, named 'test' exists...
(...)

Now I want to brute force this account, I am using
Brutus AET2 for this.

But I do not know how to use the HTML response.

Below the packet capture of a response of a login
which was succesfull:

HTTP/1.1.302.Object.Moved..Location:.start.cfm?cid=
(lines deleted)
<head><title>Document.Moved</title></head><body
><h1>Object.Moved</h1>
This.document.may.be.found.<a.HREF="start.cfm?
cid=
(lines deleted)

A capture of an unsuccessfull capture looks like this:

HTTP/1.1.302.Object.Moved..Location:.original.cfm?
login=Invalid password. Please try again
(lines deleted)
Document.Moved</title></head>.<body><h1>Object.
Moved</h1>This.document.may.be.found.<a.HREF="
original.cfm?login=Invalid password. Please try
again">here</a>

So depending on the password I get redirected to a
page...

How should the primary and the secondary repsonse
be configured?

Or does somebody else have a better idea how to do
this?

Thanks in advance!

Joh Ket
