In cases such as these, attackers use one exploit to run their malicious code and a second exploit to escalate the privileges of that code so it can perform actions that the OS normally wouldn't allow.

Amit Serper, principal security researcher at Cybereason, said his tests showed the vulnerability is located in com. He said he was unable to reproduce the exploit using a Mac's terminal window, although he said he saw reports on Twitter from other people who said the bypass worked using the terminal window as well.
