Locked ExploitsmacOS cfprefsd Arbitrary File Write / Local Privilege Escalation

[1337day-Exploits]

This Metasploit module exploits an arbitrary file write in cfprefsd on macOS versions 10.15.4 and below in order to run a payload as root. The CFPreferencesSetAppValue function, which is reachable from most unsandboxed processes, can be exploited with a race condition in order to overwrite an arbitrary file as root. By overwriting /etc/pam.d/login a user can then login as root with the login root command without a password.
