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/afp/afp_server_info
msf auxiliary(afp_server_info) > show options
    ... show and set options ...
msf auxiliary(afp_server_info) > set RHOSTS ip-range
msf auxiliary(afp_server_info) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(afp_server_info) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(afp_server_info) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(afp_server_info) > 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

Apple Filing Protocol (AFP) is Apple's file sharing protocol similar to SMB, and NFS. This module will gather information about the service. Netatalk is a Linux implementation of AFP.

The following was done on Ubuntu 16.04, and is largely based on missingreadme.wordpress.com:

  1. sudo apt-get install netatalk

  2. edit /etc/default/netatalk and add the following lines:

    ATALKD_RUN=no
PAPD_RUN=no
CNID_METAD_RUN=yes
AFPD_RUN=yes
TIMELORD_RUN=no
A2BOOT_RUN=no

  3. Restart the service: sudo /etc/init.d/netatalk restart

Verification Steps

  1. Install and configure afp (or netatalk in a Linux environment)
  2. Start msfconsole
  3. Do: auxiliary/scanner/afp/afp_server_info
  4. Do: set RHOSTS [ip]
  5. Do: run

Scenarios

Ubuntu 16.04 with Netatalk 2.2.5

  msf5 auxiliary(scanner/acpp/login) > use auxiliary/scanner/afp/afp_server_info
  msf5 auxiliary(scanner/afp/afp_server_info) > set rhosts 1.1.1.1
  rhosts => 1.1.1.1
  msf5 auxiliary(scanner/afp/afp_server_info) > run
