PS4 Exploit: 5.05 Webkit exploit released, 4.55 functional Jailbreak

4
Developer AlexZzZ just released a proof of concept exploit for PS4 Firmware 5.01. The exploit has been independently confirmed by mathieulh to also work on firmware 5.05. Combined with Qwertyoruiop’s release of a Kernel exploit for 4.55 earlier today, this means PS4 Firmware 4.55 should now be fully exploitable.

According to the Readme, this exploit relies on a fairly recent Webkit vulnerability, CVE-2017-7005, which was already used on the Nintendo Switch by Team Reswitched. (It is likely the PS4 exploit was ported from the Switch)

A lot happened in the past 24h in the PS4 scene, and we need a bit of a recap:

Typically, in order to get a functional Jailbreak of the console, one needs two exploits: a usermode exploit which gives you limited code execution control within a specific process (a favorite target is Webkit), followed by some privilege escalation to get full access to the system (the kernel exploit).

Qwertyoruiop‘s kernel exploit is compatible up to firmware 4.55 included. However, he did not provide a usermode exploit to go with it (except he had in the past already released a webkit exploit compatible up to 4.07).

With Alexzzz’s release of a webkit exploit up to firmware 5.05, we now theoretically get full access up to firmware 4.55.

M3 does this mean mod menus and such coming like on ps3 and xbox 360?


No, This means we can start doing such stuff on ps4 but not of the xbox one. Xbox one has pretty good console firmware and security.


Who said anything about the xbox one? The tittle is clearly referring to the ps4 and so is his question.. I swear some people comment just for the sake of it..

Sladren Glad to see they're making progress on exploiting the PS4, should open up the door to many other users to take advantage of and hopefully get something out and functioning!


But many people don't want to these days I'm waiting until 5.05 is fully jailbroken I give it by the end of the month it will happen I knew 4.55 would be hack but I updated my ps4. I mainly play Xbox 1 and Switch now

Awesome to hear it's released on 5.5 for the webkit.

TomPosted:

was shocked to hear about a PS4 even being jailbroken when Potion said it in the shoutbox. Glad to see this though.
