Lab Walkthrough Video:

An attacker might get administrative access to a web application. However, this does not automatically mean that the web server can be compromised. In cases where a SaaS application is made available to users, it is routine to give each user admin access to his own instance of the web application e.g. a managed hosted Wordpress site. In such scenario, the attacker who will begin accessing the application as a managed administrative user will have to figure out how to exploit the administrative interface to get a shell on the server. In some cases, it might be possible to do privilege escalation as well.

In the exercise below, the attacker has administrative access to the web application and needs to find a remote code execution attack to run arbitrary commands on the server.

CMS Made Simple is a free, open source content management system to manage websites or web portals written in PHP. 

CMS Made Simple (2.1.6) is vulnerable to a Remote Code Execution documented in CVE-2017-8912

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
