Apple may have fixed exploits used for iOS 7 Jailbreak in iOS 7.1


Over the weekend, pod2g, a key member of the evad3rs dismissed rumors that the iOS 7 jailbreak was stolen.

As for the progress on the iOS 7 jailbreak, pod2g said that “the jailbreak stuff is moving on, but slowly.”

However, if you’re waiting for the iOS 7.x jailbreak then you may want to avoid upgrading to iOS 7.1.

iH8sn0w, developer of popular jailbreak tools such as Sn0wbreeze has tweeted that the iOS 7.1 beta patches “the mobilebackup2 exploit to write to /var via the MediaDomain symlink” when he was asked if it was safe to upgrade to iOS 7.1. 

We’re not sure if this is a major setback for jailbreakers. reddit user phonenixdev explains:

Mobilebackup2 is the system used to generate your user backups, as well as place them back on the phone. But it’s designed for only particular folders in the user directory.

It has been used in years past via path walking (prepending ..’s to walk up the directory tree) to let us put files in other places in the /var partition. I’m guessing that they found they could do something similar by creating symlinks to other places on the /var partition.

Actually, I’m not guessing. I know you could do that because a failbreak I once made used that. 😛

P.S. root partition = where the OS is installed; mounted at the base of the filesystem ( / ). /var partition = where the user data is; mounted at /var. When you update your phone, the root partition is overwritten while the var partition stays around. When you restore your phone, both partitions are wiped.

Stefan Esser, aka i0n1c, believes that Apple has fixed some vulnerabilities that was being used for the iOS 7 jailbreak.

But that is just speculation at this stage as it is not clear if the exploit was being used by evad3rs to develop the iOS 7 jailbreak, so we will have to wait for them to confirm it.

But if you have been waiting for a jailbreak for iOS 7.x, then you should avoid upgrading to iOS 7.1 when it is released or even iOS 7.1 betas that has been released to developers.

If Apple has indeed fixed the vulnerabilities that was used in the in-progress iOS 7 jailbreak then it would mean that evad3rs will first have to release a jailbreak for iOS 7 to iOS 7.0.4. We thought that evad3rs may hold off releasing the jailbreak until iOS 7.1 is released, but if it does fix the vulnerabilities that is ruled out, unless they find another exploit to jailbreak iOS 7.1.
