'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.
