Command Injection II
rest-api-security | Level: Easy | Total Lab Runs: 0 | Premium Lab |
Securing an API is a critical task. A bad API design may lead to system compromise. Its impact becomes more critical when the attacker gets control over the underlying system.
A group of university students have created a Simple Terminal WebApp that was deployed on their university server. The WebApp is a restricted terminal in a browser. The developers have provided only a small set of commands to minimize the attack surface.
The issue is that the developers had not sanitized user input properly. They had place restrictions to avoid some of the command injections payloads that they were aware of and passed the accepted commands directly to the system() function if they were considered as valid by the backend server.
Objective: Leverage the vulnerability to get the Golden Ticket!
- This lab is dedicated to you! No other users are on this network :)
- Once you start the lab, you will have access to a Kali GUI instance.
- Your Kali instance has an interface with IP address 192.X.Y.2. Run "ifconfig" to know the values of X and Y.
- The Termial WebApp is running on port 5000 on the target machine having IP address 192.X.Y.3.
- The Golden Ticket is stored in a file named as "This_Is_The_Golden_Ticket_XXXXXXXX".
- Do not attack the gateway located at IP address 192.X.Y.1
The following activities are strictly prohibited on this website unless otherwise explicitly stated as allowed in the mission statement:
- Using automated scanners
- Using brute force attacks
- Denial of Service attacks
- Attacking other student machines in challenges where you might achieve a shell on the vulnerable system
- Attacking the lab infrastructure
Users violating the above will be either temporarily or permanently banned from the website.
If you are unsure about an activity, then please contact support to confirm that it is allowed on our website.
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 email@example.com 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.
