Lab Scoreboard

Securing an API is a critical task. A poor API design may lead to system compromise. Its impact becomes more critical when a crucial service gets affected like a Banking API.


The Banking WebApp allows a user to make unrestricted login attempts without placing any rate limit on the number of requests per day. Moreover, the admin user had set a weak password on his account.


Objective: Leverage the vulnerability to hijack admin's account and determine the following:

  1. Admin’s password

  2. Flag stored in the CMS used by the backend

  3. Golden Ticket
