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. Usepymsc to build.

Required:

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

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

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.
