welpwn - 💖CTF pwn framework.

项目说明

Introduction

_Pwnning is an art._

welpwn is designed to make pwnning an art, freeing you from dozens of meaningless jobs.

Features

__Tutorial__

~~Detailed Documention~~

Install

There are two ways for you to use welpwn.

setup.py has been added since 0.9.3. If you do not frequently update welpwn, and have no need for teamwork with this tool, this is the recommended way.

Via Path

This is recommended for de and those who need to share their exploit for teamwork.

Then you probably get something like this.

Template

My personal template for pwn challenge.

Core API

welpwn is a super wrapper of pwntools, using a ctx to manage binary, libc, gdb and other stuff.

ctx.start

ctx.start support process, remote and gdb.

process and remote have the same usage as those of pwntools.

gdb is similar to gdb.debug. It's con to debug at the process entry.

ctx.remote_libc

ctx.remote_libc is designed to handle the libc of challenges, which may be different from your system's.

Just assign the path of libc to it, then set ctx.debug_remote_libc to True.

__Note__

No 100% guarantee for successfully loading the libc. Segfault may happen due to different of libc.so and ld.so.

ctx.custom_lib_dir

ctx.custome_lib_dir is also designed to handle different libc, especially useful when challenges need other libraries like libpthread.so.

__Note__

If you want to debug with symbols, main_arena for example, use glibc-all-in-one to download libc.

If you want to debug with source code, just compile glibc and enjoy it.

ctx.bases and ctx.canary

ctx.bases gives you start addresses of prog, heap, libc, stack.

ctx.canary is an integer.

Note that ctx.bases.heap is a only after the process called malloc.

You can use it to prove your concept and even pre brute-force.

ctx.symbols and ctx.breakpoints

ctx.symbols and ctx.breakpoints are designed for gdb. They both generate gdbscript when you call ctx.debug(). Both support PIE and ASLR.

Check this example.

Then the following script is passed to gdb.

Use p/x $sym1 to check it.

Now support heap and libc symbols. Just use a name starts with libc_ or heap_.
