    Default 1.1.1 Jailbreak: Symbolic link exploit

    Hey folks -

    Has anyone seen this article over at TUAW:

    http://www.tuaw.com/2007/10/05/liveb...ne-1-1-1-hack/

    Sounds promising. The hack is simple: Replace your /var/root/Media folder with a symbolic link to the filesystem root on a 1.0.2 iPhone; upgrade the phone to 1.1.1; access /var/root/Media with iPhuc.

    According to this blog, they were successfully able to read and write to the file system this way. However, they were not able to execute any software because the filesystem is mounted noexec.

    Since this allows you to modify the filesystem, it seems like it should be easy enough to modify fstab (or whatever the equivalent .plist is) to mount the root filesystem without the noexec flag. Then, 3rd party apps would run normally.

    Or, one could modify crontab to launch some executable to re-mount the filesystem... or something like that.

    Basically, if you have access to system files, you should be able to modify *something* to enable root executable access.


    Anyone tried this? Anyone inspired to hack via this route? :-) (I might very well try it myself, but I just thought I'd ask around... I just lost my job, so I got lots o' time...)
