In this writeup I will share how I exploited my first ever pwn challenge on a CTF, which was a very small part of why we managed to qualify for the VolgaCTF finals in Samara, Russia! The exploit uses a format string vulnerability to leak the libc and the canary, and then we will use a stack buffer overflow to ROP and get code execution.

Today we will solve a simple pwnable challenge by inserting shellcode on the stack with a nop sled, and then jumping to it.

I wasn’t able to solve this challenge during the CTF, but I decided read a writeup and try again! In this post I’ll share what I learned.

In this writeup we will see how to run and debug a mips binary and how to exploit a simple buffer overflow.
