PSFree WebKit Exploit for PS4, QuickHEN, Lua Lapse PS4 / PS5 Kernel Exploit & Laps3c0re / Y2JB

This weekend PS4 Scene developer @CelesteBlue announced on Twitter news of a PSFree WebKit Exploit for PS4 6.00 to 9.60 crediting Sergei Glazunov and Maddie Stone (Twitter) of Project Zero for discovering the vulnerability, anonymous for writing the PSFree Exploit and himself for testing, porting and improvements alongside a QuickHEN PS4 collection incoming of WebKit exploits for PlayStation 4 System Software versions between 3.15 and 9.60 with Kernel exploits between 3.15 and 9.00 only albeit requiring more work and Laps3c0re which is a port of the Lapse kernel exploit implementation by abc using Mast1c0re by McCaulay as an entry point and Y2JB Userland code execution by Gezine using the PS5 YouTube (USA) app v1.03 PKG crediting Remote_Lua_Loader.

Here's further details from the included README.txt: PSFree version 1.2.0

PSFree is a WebKit exploit using CVE-2022-22620 to gain arbitrary read/write.

This exploit was initially for the PS4 firmware version 8.03. CelesteBlue has tested and confirmed that the original works on 7.00-8.52 and helped in making the patches for 6.00-6.72, 9.00-9.60, and PS5 1.00-5.50.

CREDITS:

• CelesteBlue from ps4-dev on discord.com for testing and porting to other firmwares
• Quentin Meffre (0xdagger) and Mehdi Talbi (abu_y0ussef) for the 6.xx buildBubbleTree() UaF exploit that served as the framework for this exploit
• Maddie Stone for the CVE writeup

Notes on reimplementing this project and testing on firmwares != 8.03:

• num_reuse and num_str must be changed if the proof-of-concept is failing
• 6.xx firmwares need a setTimeout() after a gc() for garbage collection to work. The duration may also need changing.

These values are at exploit.mjs. This implementation was tested on 8.03.

The values are implementation dependent. Even if you are on the same firmware and you test 2 different implementations, you may need to change the values.

For example, if you reimplement the project with setTimeout() callbacks instead of using Promises, even if you are on 8.03, you may need different values.

Changelog:

1.2.0:

• add support for PS4 6.00-6.20

1.1.0:

• add support for running ROP chains (PS4 8.03)
• add support for calling syscalls (PS4 8.03)

1.0.0 changelog:

• add proof-of-concept code to gain arbitrary read/write (PS4 6.50-9.60/PS5 1.00-5.50)

OLD README:

PSFree is a WebKit exploit using CVE-2022-22620 to gain arbitrary read/write.

This exploit is for the PS4 firmware version 8.03

Porting to other firmware versions:

The only non-portable parts of the exploit (assuming the firmware is vulnerable) are:

1. the size of SerializedScriptValue and the offsets of its fields
2. how to achieve an arbitrary decrement primitive

There also other objects used by this exploit such as StringImpl. They too are also subject to change between different firmware versions but are very stable hence why we did not list them.

Number 2 is used to corrupt the length of the JSArrayBufferView. This exploit manipulated the destructor ~SerializedScriptValue() to achieve the wanted result.

There is possibly a restricted free primitive via repeatedly corrupting any object that gets allocated at a JSArrayBufferView and changing its contents so that is frees another object.

For example you could modify a StringImpl to have its data pointer point to a target address and set its BufferOwnership to BufferOwned and have it destroyed.

The primitive is restricted as you can only fastFree() addresses known by the fastMalloc allocator. This means an address on the fastMalloc heap, regardless of whether it is free or not.

This means you can recreate any previous fastMalloc use-after-free exploit.

I am curious to know how many people remain in those old PS4 version that can benefit from these exploits. Is it worth it to explore options for those old systems? Or maybe it's to improve skills or possible discoveries on new versions?

 

[Franky15]

I recently got a PS4 with 9.00 again and jailbreaking via Blu-ray is working well again; I'm surprised how easy it is.

 

[xanthos84]

I also got a PS4 with 9.00 - I have ordered a blu ray writer so i can check the BR method again instead of the usb..

 

[P1nkP4nz3r]

amazing work !!! thx for this !!!

 

[malcolm111]

I just tried the new 1.2 Y2JB release with lapse, worked great! I'm now wondering whether to update to 10.01 or what till a later version is supported...

 

[Seba500PLK]

I have PS5 with 6.50 with Okage, should i wait for lapsecore or use Y2jb?

 

[malcolm111]

you can use y2jb now

 

[Seba500PLK]

I'm curious if I backup my PS5 with Okage, then do Y2JB backup, and after a few tests, go back to my Okage backup, will it work without any problems? I'm afraid I'll lose access to Okage.

 

[trocla]

@Seba500PLK Y2jb is ready to use! Also you can use bdjb.

 

[radusinborna]

y2jb working perfect on 9.60 easy setup, just make sure NOT to connect to internet before setting up some kind of block for PSN, i personally use pihole and it does the job quite good for both ps4 and ps5

for anyone looking to set it up on pihole i've used this, then set both consoles to use it using the group option in pihole, might want to set up a static IP on both consoles as well to avoid any possible issues.
