PS4 Jailbreaking       Thread starter PSXHAX       Start date Mar 29, 2017 at 2:03 PM       117,237       220      
Following the PS4 Playground for Firmware 3.55 and PS4 3.55 File Browser, today PlayStation 4 developer qwertyoruiopz made available a PS4 4.0x WebKit RCE Exploit dubbed JailbreakMe PS4 4.0x with details via Twitter below! :D

PS4 Link (click go 3 times): http://rce.party/ps4/ / local rce.rar (3 KB) via Nesterwork / Local RCE v2.rar (6 KB) via Nesterwork / Local rce v3.rar (12 KB) via Nesterwork

According to the developer's Tweets below, the bug used is a stack uninit read yielding UaF and the actual exploit does nothing but give you read/write/infoleak arbitrary JS object primitives.

He also confirmed the exploit won't work on PS4 4.50 as Sony updated WebKit past a vulnerable version unfortunately, but it's still an entry point for those on PlayStation 4 OFW 3.55 through 4.07. (y)

Spoiler: Related Twitter Tweets
Cheers to @DarkElementPL, @DoxyMarket, @hyndrid, @ryan111, @toni1988 and @vettegast for sharing the news in the PSXHAX Shoutbox! <3

But if I'd like to try to execute code for the kernel exploit, how i try this? I have to edit the exploit.js file to load in memory the file and execute?

Ok... I see the new code 2 of the exploit... I don't understand mode of code. I'm not a programmer.

But... for the programmer... with this exploit there is the possibility to try run this exploit :
