Hydra Form Module
-----------------
The hydra form can be used to carry out a brute-force attack on simple
web-based login forms that require username and password variables via
either a GET or POST request.
The module works similarly to the HTTP basic auth module and will honour
proxy mode (with authenticaion) as well as SSL. The module can be invoked
with the service names of "http-get-form", "http-post-form",
"https-get-form" and "https-post-form".
Here's a couple of examples: -
./hydra -l "<userID>" -P pass.txt 10.221.64.12 http-post-form
"/irmlab2/testsso-auth.do:ID=^USER^&Password=^PASS^:Invalid Password"
./hydra -S -s 443 -l "<username>" -P pass.txt 10.221.64.2 https-get-form
"/irmlab1/vulnapp.php:username=^USER^&pass=^PASS^:incorrect"
The option field (following the service field) takes three ":" separated
values and an optional fourth value, the first is the page on the server
to GET or POST to, the second is the POST/GET variables (taken from either
the browser, or a proxy such as PAROS) with the varying usernames and passwords
in the "^USER^" and "^PASS^" placeholders, the third is the string that it
checks for an *invalid* or *valid* login - any exception to this is counted
as a success.
So please:
* invalid condition login should be preceded by "F="
* valid condition login should be preceded by "S=".
By default, if no header is found the condition is assume to be a fail,
so checking for *invalid* login.
The fourth optional value, can be a 'C' to define a different page to GET
initial cookies from.
If you specify the verbose flag (-v) it will show you the response from the
HTTP server which is useful for checking the result of a failed login to
find something to pattern match against.
Module initially written by Phil Robinson, IRM Plc (releases@irmplc.com),
rewritten by David Maciejak
Fix and issue with strtok use and implement 1 step location follow if HTTP
3xx code is returned (david dot maciejak at gmail dot com)
Added fail or success condition, getting cookies, and allow 5 redirections by david
