How to use:
Setup a website using the downloaded files and visit it using your Wii U web browser.
This is how the exploit website looks like when uploaded to a webspace and visited with Chrome on Windows:
Alternatively visit this already prepared site provided:
It does however throw a 404 error when visiting with a computer which is not a good sign anyway.
Here's another site which shows the same as my webspace did:
The Wii U Web Browser Exploit only works for those on firmware 4.1.0. It was reported that it would also work for 4.0 and 4.03, but it’s unconfirmed at the moment. This exploit was partially blocked in update 5.0. Developers will have to find different ways to attack the exploit, in order for this to work in newer firmwares. This is only a partial exploit.
It should be possible now to gain full access. It's a work in progress. Stay tuned!
