Buffer Overflow Attack

Problem Statement

Buffer Overflow is a common vulnerability in applications which allows hackers to exploit the system using unsanitised input. The given application is known to have buffer overflow vulnerability. Develop an executable code snippet to crash the given application using Buffer Overflow vulnerability. No payload is required for the application.

Solution

Flag: In line 16 "arr[i]= arr_num;" This could lead to potential memory clogging

I was given a c++ file under the question.cpp and it was stated it had a Buffer Overflow Attack vulnerability, and I was to create a application in order to crash that application.

So I made application_crasher.py which is written in python3.8 in order to crash that question.cpp. The application_crasher.py just communicate with console and since question.cpp just needed a random number so the application_crasher.py just give a random number to console whenever there is a activity in the console.

Thus for application_crasher.py to work, just run

python application_crasher.py
