Explanation of Solution

Queue:

  • A queue is a container of objects. The objects are added or deleted according to the first-in-first-out (FIFO) principle.
  • The example of a queue is a line of students in food court of the UC. The new additions to a line are done at the back of the queue and the removal will happen at the front.

The web app is running on an AWS EC2 (Elastic Compute Cloud) instance running Ubuntu 22. Note: The point of this assignment is to step it up a notch, we learnt about different web application vulnerabilities and applied that knowledge, now we are going to pen test and enumerable the vulnerabilities of a web app + the underlying infrastructure it is running on.
