Hi, i managed to get the index.php page of a website, and i am searching for possible sql injection exploit in it.

I see some fonctions like function($param1, $param2) or function2($param) with in those a sql statement in which parameters are.
In the file, the functions are never use but it should be by the include(page), in the start, that i am not able to see...
My question is if i can initialise the parameters myself or if i have to find another thing...?

And a noobie question, can i, when my session start on the website, initialise some $_SESSION['blabl'] myself with an html form or it is just inside the website?

Thx ^ ^

Answer for question 2 is - probably not. In most (updated) php installations you can't directly manipulate $_SESSION[] superglobal array.
As for question 1 - too few information ...

Yes, as far as it without any private information.
