SpecterDev publishes writeup on the PS4/Webkit 5.02 exploit (setAttributeNodeNS)
Developer SpecterDev, following what is now becoming a tradition on his site, analyzes a recent PS4 exploit and explains it for us.
In this case, the developer discusses the PS4 5.02 webkit exploit (it was patched in firmware 5.03), currently used as an entry point for the PS4 4.55 Jailbreak. The exploit relies on a bug in setAttributeNodeNS, which led the developer (with help from Qwertyoruiop) to successful userland execution on the PS4.
The bug, being in Webkit, impacts more than the PS4, but was disclosed and patched a while ago on most systems, after being initially disclosed on chromium about a year ago.
The writeup aims at being clear for people who want to understand how Webkit exploits can work. SpecterDev qualifies the exploit as “trivial” for a seasoned attacker, but “challenging” for people who are new to it. It’s a good idea to go through Specter’s explanation if you are interested in knowing how these exploits are typically found, and have the right technical background.

First
First first first … shut t f** up
Your Momma was my First, but she wasn’t my Last.
she is dead…
he hit at it back in the day in her prime … you should be respecful and call him daddy
First what? S****d!!@
This exploit is un until 5.02 so with a new kexploit we can access to fw 5.X!
Meaning what?
meaning that again we have to wait half-year or more for release when FW 6.xx is out and problems to buy PS4 with FW below 5.02 🙁
if the webexploit is found on 5.02 why there can’t be a jailbreak for the 5.0x firmware ?
There was a unused exploit that was released a few days ago tested on 5.01-5.05 so the 5.0x firmware can be jailbroken.
5.01 has been shown running homebrew a while back through a private exploit but nothing has been released as of now.
Just wait and don’t update to 5.5 since the new webkit exploit will most likely be patched
who said there can’t be a jailbreak for 5.0x?
my bad, I meant there can’t be “for a while”
as in here http://wololo.net/2018/02/27/ps4-exploit-5-05-webkit-exploit-released-4-55-functional-jailbreak-probably-matter-days/
I’m pretty certain a ps4 5.05 jailbreak will come at some point, its just pretty hard to say when. The one thing needed now is a kernel exploit for a jailbreak to work on 5.05, and a kernel exploit has been found, but its being kept private for now, eventually it will be released though. All the stuff needed is available, just not publicly available.
There is no public kernel exploit beyond 4.55. You need a user land exploit AND a kernel exploit to do anything useful.

After reading the full write-up, I no..no.nn…..now have a stutter.
Love it so much to read this post, totally inspiring.
Thanks for your great tips
Your style is really unique in comparison to other people I have read stuff from. Thank you for posting when you have the opportunity, Guess I will just bookmark this page.
Darn, no hope for 5.03+? The other article said 5.05…
