ctf-pwn's Introduction

CTF Pwn

Warm up

The Attack Lab

This assignment involves generating a total of five attacks on two programs having different security vul- nerabilities, which helps you to understand buffer overflow bugs. More details can be seen in README.

Tools

Pwndocker

A docker environment for pwn in ctf based on phusion/baseimage:master-amd64, which is a modified ubuntu 20.04 baseimage for docker. More details in Pwndocker.

And this project will be based on a personal forked version.

Pwntools

Pwntools is a CTF framework and exploit development library. Written in Python, it is designed for rapid prototyping and development, and intended to make exploit writing as simple as possible.

from pwn import *
context(arch = 'i386', os = 'linux')

r = remote('exploitme.example.com', 31337)
# EXPLOIT CODE GOES HERE
r.send(asm(shellcraft.sh()))
r.interactive()

Template

This is a template for write-ups.

pwnable.kr

Some write-ups for pwnable.kr.

ctf-pwn's Issues

Add the attack lab of csapp in our project

This lab talks about the stack discipline and the danger of writing code that is vulnerable to buffer overflow attacks, which is quite helpful for getting started with pwn.

pwnable.kr/passcode

Mommy told me to make a passcode based login system.
My initial C code was compiled without any error!
Well, there was some compiler warning, but who cares about that?

ssh [email protected] -p2222 (pw:guest)

pwnable.kr/cmd2

Daddy bought me a system command shell.
but he put some filters to prevent me from playing with it without his permission...
but I wanna play anytime I want!

ssh [email protected] -p2222 (pw:flag of cmd1)
