PS4 Dev bigboss confirms PS4 Kernel exploit with dlclose, says next step is Jailbreak
Popular PS4 hacker bigboss (also known as psxdev) confirmed today he was able to gain privilege escalation on the PS4 through the dlclose exploit that was revealed by CTurt earlier this year.
bigboss is not sharing any source code, only some output from tools libps4/ps4link/ps4sh (so it’s a stretch to call this “Proof of concept”), but it’s great news to know that more hackers have been able to use CTurt’s work and articles, and turn them into usable exploit for their own research.
Two weeks ago, bigboss had published a similar confirmation with another kernel exploit, the now popular BadIRET exploit which has been partially leaked a few days ago.
Because no code is shared, this of course needs to be taken with a pinch of salt, but bigboss is a trusted scene member, and there’s also no reason to believe the dlclose exploit is “not a thing”, given the lengthy details CTurt has made available about it.
Privilege scalation done 🙂 https://t.co/iSoRnGxDLO

At the very end of his log output, bigboss states:
Next will be jailbreak and sandbox 🙂
Disclaimer: he’s not talking of a release here, just what the next step for his coding efforts. Details on the BSD jailbreak, etc… have been disclosed before by CTurt.

or dont u prefer softmods after all ?
i hope for a 2.5x softmod *psnremoved branch lol
damn i have a brand new ps4 on 2.56 I have a few games I’m dying to play is it worth waiting?
I think this dlclose exploit is working until FW 2.57 but you still need to run the 1.76 webkit exploit to run a piece of code
Could you please let me know your source of information about the dlclose exploit working up to FW 2.57? ‘Cause I’ve been searching the web for hours and couldn’t find anything exact. It’s very important. Thank you very much in advance.
Ok still waiting am on very first ofw loolow!
Maybe we will get a cfw confirmation on april 1st? 😛
I think it’s all bull$#!+.
just publicity…
Fimo quote “dlclose exploit is working until FW 2.57”
could u make a howto for my ps4 on latest fw ?
or should i buy an older package ps4 console for it ?
You need a userland exploit on 2.57 too in that case. For now the only public userland exploit is the webkit one on 1.76
