 |
|
As one current exploit couldnt be patch that was in 5.51, it seems like it works in 5.55 ofw.
http://www.psp-hacks.com/2009/08/09/psp-firmware-5-55-still-vulnerable-to-mohh-exploit/
Is there any use of this exploit to users? Could it help to aleast make a HEN version of 5.55 so users can run it on there psp along with other things?

it isn't possible to make an HEN without a kernel exploit. and we haven't got any kernel exploit on 5.55...

There is a 90% chance someone has found one but not released it, they are waiting for the Go! and if they release it Sony would patch it |

Sony PSP Go could have some new security features build within it. Medal of Honor Exploit is good, but we must find a away to use the kernal mode. For now, usermode is good for developers to make emulators. You can also access the ram in VSH mode (if the exploit even allow thats), or someone can make a kernel prx to install hen onto the psp.
Sony wouldve patch this exploit, but maybe they havent know that the wifi can be use as a exploit. Maybe other games that support for wifi can also do the same.
EDIT:
I think that they didnt patch it because they are releasing the PSP Go soon.

I would rather make an eloader to make use of existing emulators. Pretty useless to adapt each emultor to a new exploit, don't you think?

How would you do that? It's a game exploit, I remind you :P
| Quote: | | someone can make a kernel prx to install hen onto the psp |
Huh? How would you run a non-signed PRX? If you can, how would you load it on kernel mode? :P

Sony can't patch a thing as it is a MOHH exploit, not a FW one. The vulnerability is a format-string one on MoHH code. So EA should patch it, not Sony. And I doubt that's going to happen. You can even expect the same vulnerability on MoHH2.

that's true, but i saw references to some hackable games (lumines, gta, ecc) in umdman.prx. strange thing...

Sony also patches games themselfs with firmware updates, they just haven't bothered yet with Medal of Honour. I'm pretty sure that by the time the PSP Go is released, they will have bothered. |

It just might be that Sony never expected wifi games to be an exploit. I wonder how they patch the UMD exploits.

Sadly not...
Anyway, Sony can't patch the UMD once it has been printed, granted, but they can (and have, in all the previous user mode exploits) patch the firmware so that the exploit doesn't work.
And also, the reason that it works in 5.55 is probably the same reason that the tiff exploit worked on 5.05 - It is probably just a release to fix SDK bugs as required by some games.

Do you know where they patch it at? UMD eboot.bin and boot.bin are patch by Sony so it can do different things.

How can you patch the game's code? That's not possible, unless they patch it on the fly when loading the game into memory... Which I don't think they do (or do they? xD)
I think you're talking about patching kernel exploits found through those games, or maybe those game exploits rely on a FW code vulnerability, which is not the case here. Cannot see how Sony can patch other developers' code without having the code in question, retire all UMDs from market and printing them again. Or radically change the firmware inner working (for example marking stack as non-executable, which cannot be done on PSP, afaik), which is not an option because they'll lose compatibility.
Btw, did they patch the Gripshift exploit?

No, they modify the savedata modules in order to check for eg. the buffer overflowfor a specific game in the savedata, and tell the game that it's corrupt if they find it. And yes, they fixed the GripShift exploit in 5.03. |

Ok I got it. Weird behaviour anyway. That savedata module will be a couple of megs bigger in a couple of years xD

Sorry, let me make it clearer.
In the pass, they patch the eboot.bin and boot.bin in the umd to stop exploits. Now these days, they make a patch for the psp it self to stop UMD exploits (or the one been founded).
