Report: new VSH user mode exploit found?

Posted Sep 8, 2010 at 3:06PM EST by Glenn M.

Listed in: PSP Tags: Exploit, homebrew, wololo

psp_f The forums down at Lan.St have gone abuzz yesterday after a possible buffer exploit has been found. Details are being carefully kept under wraps at the moment to protect the new discovery, but homebrew veteran wololo has confirmed that it's legit and is hopeful that it could lead to a new breakthrough.

wololo, whose name is often heard alongside the Half Byte Loader, noted that the new exploit is a "very nice VSH user mode exploit (or very close to it, since there is full control on ra)." He also expressed willingness to work on the new exploit, though he himself admits lack of experience in dealing with VSH vulnerabilities.

This user exploit also seems to need a kernel exploit, which is similar to how ChickHEN worked. There is plenty of speculation surrounding its possible uses, but everything's still up in the air for now.

We'll be keeping an eye out for updates as they come.

Hey, any exploit found these days is golden. Hopefully the HBL genius can make good use of it seeing as his HBL project is getting rather far on 3000s and Go's. If this keeps up, I may go out myself and grab a Go (foolish on Sony's part... had the Go been hackable, I bet the unit would have flourished in sales!!). Here's some good luck to ya wololo!

Disagree.

Even if PSP go was hackable, that wouldn't make up for the tiny buttons the PSP go has.

Way better to get a PSP 2000/3000.

you can't even control movement and caera at the sae time with monster hunter on that piece of ^%#&%*(

# RE: Awesome! — But Fukir 2010-09-09 16:39

Clamshell would have been the better idea.

The PSP's biggest drawback is the exposed screen and needing a pouch or plastic layer to protect it.

The go does all sorts of other things except address the biggest drawback.

But adds on a few more difficulties to boot.

Just another bad idea from sony's bad idea catalog.

Great . Now maybe we can have more piracy on PSP go.

# RE: RE: Report: new VSH user mode exploit found? — PS3 Owner1 2010-09-08 22:11

It's homebrew not piracy, try to separate, you fool.

# RE: RE: RE: Report: new VSH user mode exploit found? — But Fukir 2010-09-09 16:41

Yeah, you fool!

Shhhhh!

;)

New custom firmware??????

# Hmmm — Cortador 2010-09-08 22:08

This was not supposed to be out in the wild...

# :l — Vez 2010-09-08 23:06

*Heres hoping for a new custom firmware*

# make some things clear — DarXPloit_$a1 2010-09-09 03:35

0) This Buffer Overflow isn´t fully exploit for now. It will be the next days.
1) Only this Buffer Overflow Exploit won´t lead to something useful.
2) For maximal usage we need a kernel exploit too (they are more difficult to find than vsh exploit´s like this one)

.
3) If we have this 2 components, even then we couldn´t install a a Custom Firmware. Only a temporary Custom Firmware, like in the 5.03 ChickHEN R2.
( If you have a psp with Date Code 8b or lower you are able to downgrade

)

# My little secret is no more — ukbeast 2010-09-09 10:12

I am the person who found this.
Just need to say that before I lose credit for the discovery.

# RE: My little secret is no more — zero233 2010-09-10 00:08

yea i seen your first post over at lan. dont let ANYONE take all the credit for this. by the way nice find

don't worry ukbeast,no one will still it from you and you'll have your credit ;)

don't worry ukbeast, no one will steal it from you and you'll have your credit

Did you vote yourself up?

Lol.

Thats one way to do it.

you got mine

# ukbeast — DarXPloit_$a1 2010-09-09 17:21

yeah, don´t worry ukbeast

.We all have to thank you for your usermode vsh exploit, which gives us the opportunity to port a kernel exploit. I´m sure you won´t lose your credits. You get your credits in the hello world they will make

.
But for sure we will need a better shellcode for this, which searches the required stubs (sceIoOpen, Read, Close ) on runtime.
I´d like to see how they will do this

# too lazy to log on — Kyl.Blz 2010-09-09 18:27

everyone thats hoping for a new cfw doesnt know shit about the psp and should stay out of these types of announcements forever

# VHS — Awwe 2010-09-10 12:05

Dammit, thought it said VHS exploit.

Sure would be nice with VHS compatibility

# Kyl.Blz — __Flyer__ 2010-09-10 12:57

lol, actually right.
and DarXPloit_$a1 who don't have files and haven't seen crash itself and have nearly no clue of what this all about

# Flyer — DarXPloit_$a1 2010-09-10 14:54

hey, I know what file format it is

if you want to discuss, please contact me on lan.st . I know what i´m talking, no matter

If you know how to make an binloader, which is able to search stubs on runtime , contact me too. I need one

but don´t know where to start

# Bah — SonicTH 2010-09-11 16:11

This is less interesting these days because of how far behind the actual hacked Firmwares are. We're barely scraping by with making modern games playable.

# RE: Bah — KylBlz 2010-09-13 18:53

because they havent added any worth while features to new firmwares, also the great kernel overhaul of 6.20 really puts a damper on things, that and we dont have many experienced enough devs to make a cfw on the scene anymore because people keep running them off..

# You kids — la popola 2010-09-14 18:14

Official firmware, ftw. You all just want to pirate ISOs. Dont even deny it, kids.

Buy your games instead of being a winey little douche expecting an exploit to come out ;)

# RE: You kids — KylBlz 2010-09-15 02:39

Well "son" if you knew anything about the PSP (which you don't) then you would realize that this *could* enable home brew ONLY, never ISO's. So, your condescending attitude doesn't fly when real grown ups are around mmk?

# well.. — DaniPoo 2010-09-14 21:09

Well we all hope that this could lead to something. And hope that som old hacker has a kernel exploit lying around.. Then this could he really usable.. And I think there is. Dark alex said something before he disapeared about finding e kernel exploit. He never released it if I remember corectly. And there has benn a few people claiming to have found kernel exloits. And if you think about it that way.. There might be some hope left after all

# @DaniPoo — DarXPloit_$a1 2010-09-15 16:50

You shouldn´t hope , it will lead to something. Only thing that is missing for now is a kernel exploit. That ´s just a matter of time

# Johan — Johanshow 2010-09-16 03:21

给力！！

# its sad — la popola 2010-09-19 13:17

You kids are just going to use this for piracy, which is just sad. Official firmware is best. Buy your games, earn your money, and stop being such a cheapass.

# RE: Report: new VSH user mode exploit found? — w7y7a7t7t 2010-09-19 22:45

maybe i'll finally get to play birth by sleep on my go, and not my sisters 3000

# HEY! — mmmmhmmmm ... 2010-09-28 18:32

I have a feeling la popola works with sony because he wants us to buy games, if you want us to buy psp games give us 200$ too do so then!
