ROBChain

PoC exploit for Super Smash Brothers Wii U to get arbitrary ROP execution under userland

Can go over any fighter (and possibly article) to gain arbitrary code execution (Only ROP atm). This is a variation of contenthax based around MSC (the main character scripting language) exploiting a heap overflow to gain arbitrary read/write within the MSC script. Use pymsc to build.

Build PoC

Required:

Python 3.6 or greater in path as python3 (Edit Makefile for other configs)
make
php
A copy of the wiiuhaxx_common release files (>=0.3 inside a folder wiiuhaxx_common.

git clone --recurse-submodules https://github.com/jam1garner/ROBChain.git && \
cd ROBChain/poc && \
make clean && make

Install

Take the generated exploit.mscsb and install it in a patch over

/data/fighter/[fighter]/script/msc/[fighter].mscsb

then install via SDCafiine or fs contents replacement.
