PS4 Jailbreaking       Thread starter PSXHAX       Start date Mar 29, 2017 at 2:03 PM       118,001       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)

We know new PS4 consoles are currently shipping with 4.0x OFW, so chances are if you grab one it will be under 4.55 (most likely 4.06 or 4.07). (-8
