Buffer Overflow is a vulnerability in which a less privileged user gains unauthorized access to a shell with same privileges as the program's current executor by overwriting beyond the maximum buffer size. Once a hacker gains privileged access severe damages can be inflicted on a machine. This vulnerability often exists in programs written in C/C++, languages wherein the developer must manually manage the memory footprint. You will be given a binary file which has a buffer overflow vulnerability that you need to find and exploit using gdb(GNU Debugger) only! You also need to write a detailed Write-up on how you completed your task and successfully exploited the Buffer Overflow.

Deliverables:

Share the link to the write up with the ASCIINEMA. For the write up, you may use any platform of your choice.
