A shopping cart application allows users to purchase laptops at low rates. The application makes use of JWT tokens for authorization purposes. With every product purchased, the user gets an invoice.
The application is still in the BETA phase so registrations are not accepted. Instead, a few selected individuals are provided access! Conclusively, the backend is SQLite-based due to the small size of the BETA members.
The application had suffered a breach the previous month and had tightened the security since then. Data retrieval is done with proper security practices to avoid any injection issues. But some artifacts of the breach might be present and could be of great value during this pentest exercise.
Objective: Leverage the misconfigurations on the backend server and retrieve the following:
Flag retrieved from the exposed HTTP server
Password for firstname.lastname@example.org
Flag retrieved after successful purchase by performing parameter tampering attack
Password for user corey after retrieving all the invoices from the backend leveraging the lack of rate-limiting
Flag present in the home directory of the compromised user, that is, corey
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 shopping cart application should be running on port 5000 on the machine located at the IP address 192.X.Y.3.
Do not attack the gateway located at IP address 192.X.Y.1
NOTE: This badge challenge is for evaluation, so we don't provide hints or explanations for this. Hence, contact us on support email only if you are facing a technical issue.

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 firstname.lastname@example.org 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.
