PS4 Jailbreaking       Thread starter PSXHAX       Start date Mar 29, 2017 at 2:03 PM       117,234       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)

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

commericals should last only a few days; i am sure he has to live too. give it a few days, or a few weeks, if nothing, only then we are in trouble.

Im pretty sure it was the dudes birthday yesterday, give him a chance! He will have a life too.

On a side-note of this have any of you guys bought a PS4 pro recently, say in the last 2 weeks to a couple of months? If you have what firmware did it ship on? I know itll be under 4.5 but not sure how low it'll be.

Long story short friend of mine needs a ps4 pro and cant wait for delivery, hes offered me more than its worth to take mine, i know 4.07 seems to be safe, but 4.06 seems to be the one most are working on at the minute, and I ideally want the option to update to it.
