TheFlow has done it again--a new kernel exploit has been released for PlayStation 4 consoles. This latest exploit is called PPPwn, and works on PlayStation 4 systems up to official firmware 11.00, with support for 9.00 as well. The exploit was known about for months, and was eventually patched by Sony in a PS4 firmware update for 11.02, after TheFlow reported the vulnerability on HackerOne.

PPPwn is a kernel remote code execution exploit for PlayStation 4 upto FW 11.00. This is a proof-of-concept exploit for CVE-2006-4304 that was reported responsibly to PlayStation.

Supported versions are:

• FW 9.00
• FW 11.00
• more can be added (PRs are welcome)

The exploit only prints PPPwned on your PS4 as a proof-of-concept. In order to launch Mira or similar homebrew enablers, the stage2.bin payload needs to be adapted.

The GitHub repository is available linked below, with instructions and further details about the exploit. You can also find important information regarding all PlayStation 4 exploits in the GBAtemp PS4 Exploit Guide.

any one can explain to me what this does ? iam on 9.3

Absolutely nothing for now.

Too many people are thinking this proof-of-concept kernel exploit is a jailbreak, but it's not.

This is just an entry point that others will have to implement for anything useful to happen (jailbreak).

Stay at or below 11.00, because another kernel-level exploit will be years, if not longer (or impossible now), to be found.

Problem with PC games on Windows ect. Is that they're always poorly optimised

Popular games on PC do tend to get mods but yeah is a matter of "playing the game now" or "Playing it years later on PC with mods."

Honesty with Ratchet & Clank: Rift Apart PC release being okay, I see no reason to buy a PS5 when everyone other game I care about is also on Xbox or Windows, and it being on Xbox means a PC release exists or may be coming. Then again I have no Xbox .

If I got a powerful new PC... that would have to use Windows 11 -_-

I booted up my PS4 the other day to play bloodborne and noticed it was on OFW 7.50. If I want to do this in the future, is there any way to block updates?

Yeah, just stay offline, there's an option in the settings menu that lets you disable connecting to the internet.
Also check that there are no updates ready to install, if there are you can delete them.

first DONT update. second it means you can "hack" your PS4, and play backups and homebrew among other things. just when? not sure.

Not really true. PPPWN is a full jailbreak chain in this release for the PS4, the only thing that needs to be done is a payload injector needs to be updated to support this jailbreak and that's it.

GoldHEN is already running on it and in testing phases, just not released to public just yet.




The PS5 version of the exploit, however, will not be a full jailbreak, as while it does get root access, it'll still need a userland exploit to get past some of Sony's newer security measures, so the PS5 release will take a lot more time. I wouldn't be surprised if we don't see GoldHen within a week.

Soon from look of it.

It seems this is the only option for now haha. However I'm using my steam deck to remote play, but the updates don't auto install, so there doesn't seem to be any troubles if left downloaded.

Do you still have to use a usb to enable homebrew?

 

[kevin corms]

Anything exciting homebrew wise yet? Might track down a ps4 if its useful for more than just pirating games. I much prefer to play ps4 games on a ps5 if I can.

Yeah, and right now publicly, PPPwn does nothing for end-users, which was my entire point.

It's not useful as it is right now.

Are you talking about 9.00 where the USB has to be used to boot into HEN?

If so, then no. This exploit uses the ethernet port instead.

Man, I'm on Firmware 11.02.

You can still revert back to 11.00 or whatever firmware you previously had, but it's a lot of work.

Is this going to work on ps5?

Don't think so...

 

[scroeffie1984]

any one can explain why cfw is not possible ?

 

[linuxares]

It haven't been properly cracked. No signing keys etc are in the wild

Yeah, that does look a bit 'involved' just to go back one update. I'll sit tight for a while to see if 11.02 gets added someday.

Not unless you only want to play last gen games.

And most current gen games lol. It's crazy how long it's taken for the majority of new games to not also still come out for the last gen hardware.

You can get a fairly decent PC for about $700 now.

There hasn't been a time this century when you couldn't get a fairly decent PC for about $700. My $850 PC from 2020 still runs all the latest games at acceptable framerates with RT and has better backwards compatibility with Nintendo, Xbox and Sony games than real hardware thanks to exceptional emulation. Would I have been better off with a PS5 for $200 less?

LMFAO!

 

[Subtle Demise]

Playstation hacking sure used to be exciting.

Yep. Miss the PS3 days.
