What service should be blocked at the firewall to prevent this exploit being used?"Įmil Kvarnhammar: "This is a local privilege escalation. What sort of access is required to one of them, for this exploit to be used by attackers? All our machines are behind a firewall, but obviously some services are open to our machines. John Car: "My family are all using Apple machines with 10.9.5 for various reasons. Thank you for the work, finding this, and getting it patched." I only know because I have spent so much time chasing it personally. I believe there are far more people compromised than anyone realizes because of this. I think this may finally put to rest an issue that no one, including apple have been able to help with, and which I have been in able to solve on my own.
In reading your exploit, I found a number of similarities to my situation. All of my knowledge is self taught through research on how OS X works, and researching the error messages that were telling me something just wasn’t right. I am an amateur OS X security enthusiast, due to the fact that I have been dealing with this exact situation for years now, on multiple systems. Gareth Davies: "What’s the view on delaying public disclosure on such a serious security flaw? I understand the reasons for agreeing that Apple should have more time to fix it but shouldn’t a $770 billion company have worked more quickly on this one? If a white hat found this it’s possible, I guess, that less principled parties were actively using it having discovered it independently."Ĭhris Baldwin: "Great work.

We recommend that all users upgrade to 10.10.3.

OS X 10.9.x and older remain vulnerable, since Apple decided not to patch these versions. The intention was probably to serve the “System Preferences” app and systemsetup (command-line tool), but any user process can use the same functionality.Īpple has now released OS X 10.10.3 where the issue is resolved. It’s been there for several years (at least since 2011), I found it in October 2014 and it can be exploited to escalate privileges to root from any user account in the system.
The Admin framework in Apple OS X contains a hidden backdoor API to root privileges. You can also read Emil Kvarnhammar's original and very detailed blog post on TrueSec about this flaw in OS X's security safeguards: Security researcher Emil Kvarnhammar has proven that with the publication of a hitherto unknown back-door API in the operating system which allows any user to break free of a restricted account and gain system-level privileges.

Apple users are being advised to upgrade to the latest OS X release, version 10.10.3, as soon as possible following the disclosure of a hidden API which allows back-door access to a system-level account.Īpple's OS X is frequently touted by its fans as inherently more secure than Microsoft's Windows, and while there is some argument to be made that its adoption of POSIX-compliant permissions and other Unix-inspired security systems make it a harder target it's a fact that any complex software stack is vulnerable to attack.
