Basic Usage

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

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

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(ftp_version) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(ftp_version) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(ftp_version) > 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

Description

This module allows us to scan through a series of IP Addresses and provide details about the version of ftp running on that address.

Vulnerable Application

Install ftp server on Kali Linux:

  1. apt-get install vsftpd
  2. Allow local users to log in and to allow ftp uploads by editing file /etc/vsftpd.conf uncommenting the following:
    local_enable=YES
    write_enable=YES
    chroot_list_enable=YES
    chroot_list_file=/etc/vsftpd.chroot_list
  1. Create the file /etc/vsftpd.chroot_list and add the local users you want allow to connect to FTP server. Start service and test connections:
  2. service vsftpd start

  2. Do: set RHOSTS [IP]
  3. Do: set RPORT [IP]
  4. Do: run

Scenarios

vsFTPd 3.0.3 on Kali

msf > use auxiliary/scanner/ftp/ftp_version
msf auxiliary(ftp_version) > set RHOSTS 127.0.0.1
RHOSTS => 127.0.0.1
msf auxiliary(ftp_version) > set RPORT 21
RPORT => 21
msf auxiliary(ftp_version) > exploit

[*] 127.0.0.1:21          - FTP Banner: '220 (vsFTPd 3.0.3)\x0d\x0a'
