At the moment, it is clearly unsafe to run I appreciate your skills and helps and interested to hear your further thoughts on the best approach from this point forward? Thanks for the kind compliment, but sadly it is one I cannot accept; I am merely an itinerant technician, not a coder. As for moving forward, I would assume that OS X versions prior to I do completely see some strengths in your points…. At this stage AFAIK the thread is starting to get long only some versions have been confirmed as exploitable as standard user, rather than admin. Sure the code is already out there now.
What Apple have failed to do here is provide a Fix to supported platforms They have only provided a solution which many will find unacceptable.

I am just struggling with how we can collectively and responsibly do that given the unusual circumstance, the lack of solution and severity of the problem. The fact is all platforms have issues from time to time, but this one is serious and we security minded folk all share some responsibly in educating the entire software development community that these practices are not acceptable. I have filed a bug request and to my utter surprise even got from APPLE this in response within 24h: — We are aware of this issue. It is being investigated. Thank you for taking the time to pass it along to us.
Congratulations Apple. You left me no other choice. I saw Richard Stallman give a talk once, about 15 years ago. Despite not wearing shoes — he was right about Open Source. Mac OS X is free as in beer. Like Liked by 1 person. It only succeeds if I enter the corresponding credentials. Is it safe to assume that Also, the file is read-write by everyone and rwsrwxrwx.
I my memory served me right, there were TWO system updates last week. Anyone else out there experiencing the same issue? I have to say I thought exactly the same thing when reading the timeline…wow, billions of dollars and the most valuable brand in the world, all those software dev.
Kick ass job Emil for reporting this to Apple and creating the PoC. It is not vulnerable to the original PoC code.

So Patches are issued to fix a system while maintaining full functionality. More updates regarding Rootpipe, about how the patch by Apple in Patches for OS X Umm you mentioned patches for OS X After all, it seems that Apple could be convinced that this vulnerability deserves to be fixed also on Mavericks!
Would that be the Admin Framework part that addresses Rootpipe, meaning applying Security Update will secure Mavericks as well? Sorry for the late response. But according to this article OS X No physical access would not be needed.
You would however need code already running on the machine in userland to exploit this. That potentially harmful code could have gotten on your machine in a number of ways.

Building a nice demo The first exploit I used was based on CVE , a sudo authentication bypass bug that was patched in version I found the following code through a quick disassembly in Hopper: Okay, so the systemsetup binary simply checks if we are running as the root user?
I tried doing this in my own code, but got the following error: Attempt to send message without connection! I went back to the systemsetup binary again and found the following: It seems like the result of [SFAuthorization authorization] could do the trick. The file is finally created, and setuid bit is set: -rwsrwxrwx 1 root wheel Apr 1 rootpipe. It is as simple as sending nil to authenticateUsingAuthorizationSync instead of using the result of [SFAuthorization authorization]: [sharedClient authenticateUsingAuthorizationSync: nil]; It seems like the authorization checks are made by triggering callback functions on the auth-object supplied.
Our recommendation to all OS X users out there: Upgrade to Rootpipe Full Disclosure live walkthrough, and much more… I will explain all details of the rootpipe vulnerability in my session at Security Conference , May 28 in Stockholm , Sweden.
