The exploit for the bug I presented last March at SyScan360 is today one year old so I decided to release it. I wasn’t sure if I should do it or not since it can be used in the wild but Google Project Zero also released a working version so it doesn’t really make a difference.
I’m also publishing here the final version of the slides that differ slightly from the version made available at the corporate blog.
The exploit code is slight different from Ian Beer exploit so you probably might want to give it a look. It’s a pretty clean and neat exploit.
You can find Ian Beer’s blog post about this bug here. Bug collisions are not fun, I expected this bug to be alive for a lot longer but Ian Beer is awesome, so hat tip to him.
The bug itself is super fun since it allows you to exploit any SUID binary or entitlements, meaning you can escale privileges to root and then bypass SIP and load unsigned kernel extensions with the same bug. Essentially, massive pwnage with a single bug. The only thing missing is remote code execution. Ohhhhh 😦.
Every OS X version except El Capitan 10.11.4 is vulnerable so if you are running older systems you should consider upgrading asap (they are also vulnerable to other unpatched bugs anyway!).
