Proceeding his PS4 ROP 8CC Port and the 7.02 PS4 Kernel Exploit (KEX) release, PlayStation 4 scene developer sleirsgoevy added a work-in-progress (WIP) port of the PS4 Webkit Bad_Hoist 6.XX Exploit by Fire30 to his Github repository noting it should work up to 6.72 but requires some minor changes and offset adjustments. :geek:

In related news, @zecoxao shared via Twitter a PS4 dump file pack including webkit, libc, libkernel, gadgets and syscalls from 6.72 Firmware and kernel, libc, libkernels and libSceWebkits decrypted from 7.00 Firmware which can also be found below. 💗

:alert: As covered previously, it's recommended not to update your Firmware until a full PS4 6.72 jailbreak is publicly released. :alert:

And from the README.md: bad_hoist

This is an actually working implementation of Fire30's bad_hoist exploit.

Supported firmwares

This exploit has been tested and proven to be working on FW 6.51. This should work up to 6.72 with minor changes, however various offsets need to be adjusted.

ROP compiler setup

In order to run the ROP compiler you need to have dumps of WebKit, libc & libkernel.

Run make and follow instructions to obtain the dumps.

Dependencies: python3, gcc, ROPgadget

Assembly-like ROP format

This toolchain uses assembly-like ROP format that is briefly described below.
Code:
<label>:
Declare a label. Labels are global and should be valid Python identifiers.
Code:
<asm_instr>
Find a gadget that looks like asm_instr ; ret and insert its address. Will error out if the gadget is not found inside the dumps.

Note: after dumping you can find a dumps/gadgets.txt file.
Code:
# comment
For each line, every character after the first # is considered a comment.
Code:
db <expr>
(<expr>) must be a valid Python expression that evaluates to a collection of integers in range(256). The corresponding bytes will be written into the ropchain.

Examples: db 1, 2, 3, db bytes(256)
Code:
dq <expr>
<expr> must be a valid Python expression that evaluates to an integer. The integer will be written into the ropchain as a 64-bit little-endian value.
Code:
dp <expr>
Same as above, but <expr> should evaluate to an offset from the start of the ropchain. This will result in an absolute address being written.

For example, the commands
Code:
pop rsp
dp label_to_jump_to
will perform a jump.
Code:
$<expr>
<expr> should be a JavaScript expression that evaluates to an integer. The expression will be executed inside the exploited WebKit and the result will be written into the ropchain as a 64-bit little-endian value.

Example: $infloop_addr

Note: in JavaScript numbers only have 52-bit precision.
Code:
$$<expr>
<expr> will be inserted into the resulting JavaScript code literally.

If <expr> reads exactly pivot(ropchain);, the final pivot statement will be omitted.

Example:
Code:
$$function(some_params)
$${
...ropchain...
$$pivot(ropchain);
$$}
See examples of this language in the rop/ directory.

ROP compiler usage
Code:
usage: python3 rop/compiler.py <rop_source> <gadgets.txt> > <rop_js>
<rop_source> is the ropchain source code in the format described above.

<gadgets.txt> should point to dumps/gadgets.txt (or an alternative gadgets file in the same format).

<rop_js> is the resulting JavaScript file that should be executed.

Running ropchains

To run a compiled ROP chain, add the corresponding <script> tag to the end of index.html, then load that page in the PS4 web browser.

It's usually wise to release such things in bits and pieces across multiple contributors, as nobody wants to become a target for another $ony lawsuit.

Hopefully someone will pick up where they left off fixing the 'minor changes' and adjusting the 'various offsets' required for 6.72. :sneaky:

It's good to see you always raising the flag of hope and that's what I like most about you our dear Moderator. And yes we hope some other hero continue the great work and to put an end to this scenario soon
