pUm is right. You can download the code form Cake and see for yourself. In cake\libs\session.php you will see the following check: if ((Configure::read('Session.checkAgent') === false || $this->_userAgent == $this->read('Config.userAgent')) && $this->time <= $this->read('Config.time')) { Hope this helps Cheers, Marc On Wed, Jul 1, 2009 at 4:00 PM, pUm<hijacka () googlemail com> wrote:
just a gues, but try to fake the user agent. something in the http header must be part of the cookie auth. so try them all and then reduce.

I'm almost sure the authentication mechanism is carried by a cookie but I'm unable to impersonate another user using its cookie. The probe I do is opening two sessions with two different users (one in internet explorer and one in firefox). Then I copy the cookie belonging to one user and substitute it in a request done by the other user (using WebScarab). The app throws and error and disconnects the validated and legal user. I think that some info is stored in server side about the client who owns each cookie. Is this possible? Is it the normal operation in sessions in CakePHP? Any info or pointer would be very useful. Thanks.
