Lab Walkthrough Video:


Developers have created an open system containing user information and the backend uses GraphQL. This enables users to request the necessary data in a single request to the API.

The developers have put a constraint that the search would only work if the name or email of the person is supplied (for authorization purposes). So this prevents anyone to dump the whole database and retrieve the sensitive information of other users.

The issue is that the developers query the SQL database with the user-supplied input without properly sanitizing it and send the results back to the client.

Objective: Leverage the flaw to dump the database entries and get the password hash of admin user (isAdmin = true).



Verify:
1. Password Hash of admin user

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  attackdefense@pentesteracademy.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.
