Apple Mac OS sierra has got a serious bug in their software which allows any user to login with administrative access without a password.Strange right.Just with a username as root and no password gives you administrative access. How much secure your system is, this simple flaw allows anyone to read/write files in the system. Lemi Ergan (Security Researcher ) found this bug and irresponsibly posted on Twitter. Irresponsible in the sense it was a serious bug and he has to first inform Apple and after giving some time for them to rectify then he has to post.
Apple within 18 hours made a patch to rectify the problem. It worked fine but Apple released an update to the Apple Mac OS sierra. The new update rashes out the root bug patch and the root access problem again occurs. Even re-installing the root bug patch won’t work. The only way to get rid of this root bug is to go back to the previous update and install root bug patch or Apple has to release another update with root bug patch. This root bug patch seems to be less vulnerable if we are using in personal, but if we are connected to a network then this bug allows anyone to get into our system with administrative access.
