So as most of you who read this section probably know, the other day Fire30 ported the PSVita exploit from HENKaku (originally developed by xyz), and I decided to build a project around this exploit. Where the original POC made you setup a python server on your PC and such, with PS4 Playground, everything works straight through your PS4's Web Browser. It was a bit of an annoyance to make everything work, especially when the exploit would crash the webkit process as soon as it was finished executing, however with some magic I made it work.
I stabilized and cleaned up the exploit a bit, and designed the site, however the credit for the exploit goes to Fire30 and xyz, and the original idea for PS4 Playground as well as the JuSt-ROP project all goes to CTurt. If you have anything to contribute, please feel free to fork the repository and submit a pull request.
Requirements
You will need FakeDNS to spoof manuals.playstation.net, you will also need XAMPP to run an apache host for PS4 Playground to run on. To quote the readme;

You will need fakedns. You also need to edit the dns.conf to point to the ip address of your PC (can be found in cmd/terminal by typing ipconfig/ifconfig), and modify your consoles' DNS settings to point to your PC's address. Then type the following in your terminal;
python fakedns.py -c dns.conf
You will also need to setup xampp on your computer and run Apache on port 80. For the easiest method, in /htdocs, create the '/document/en/ps4' directory and place the files from this repo in there.
When your fake dns is running and you've setup your localhost server in xampp, you can navigate to PS4 -> Settings -> User Guide. It should then show PS4 Playground.
python fakedns.py -c dns.conf

Notes
The exploit will not run correctly all of the time. Sometimes it will stick at stage 4 or webkit will crash before the script is finished. If it doesn't work at first, keep trying until it does, it shouldn't take long.
Refreshing the page after a successful attempt or going to another page will crash webkit. Just hit OK and it will resume to the next action you wanted to perform.
The project isn't 100% complete, it's an on-going work-in-progress.

While the exploit and PS4 Playground aren't incredibly useful at the moment, if and when a kernel exploit is found, things will get a lot more interesting

Updated, now ROP works (however it is unstable). Modules are shown in system info when you do a Technical + Module Evaluation. The PID of the WebKit Process is also shown if you do a Basic Evaluation, and there were some bug fixes. I couldn't make the PID fetch (syscall #20) and module fetch (syscall #60
work together as it would instantly give a segmentation fault. Hopefully this can be fixed in the near future. You may also get two different PID's in succession when running Basic Eval, this is because WebKit is actually split into two processes. You can read more about this You must login or register to view this content. (control + F "getpid"), article written by CTurt.

As pointed out by B7U3 C50SS, removing the hashtag from the end of the URL seems to help in regards to crashing and receiving blank pages, this has now been implemented into the official branch.
