Assignment 3 - Binary Pwnage
Assignment 3 is due 3/15/19 on or before 11:59:59pm EDT.
Description
For this homework assignment you will be granted access to a Virtual Machine (VM). The VM will have its own set of login credentials. The server will have several binary challenges to solve. To solve each challenge you must recover a “flag”. All flags will have the following format: flag{abc}. Submit this flag to the web submission server discussed on piazza for points towards your homework grade.
Binary Exploitation
In this Binary Exploitation assignment, your goal is to steal the contents of flag.txt located next to each respective challenge, by obtaining a privileged shell. Obtaining this privileged shell is done first by identifying the vulnerability, then developing a working exploit. Once you have a working exploit that has provided a privileged shell, simply execute cat flag.txt to obtain the flag. Submit this flag for points.
