Module Overview

Name: CCTV DVR Login Scanning Utility
Module: auxiliary/scanner/misc/cctv_dvr_login
Source code: modules/auxiliary/scanner/misc/cctv_dvr_login.rb
Disclosure date: -
Last modification time: 2017-07-24 06:26:21 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): 5920
List of CVEs: -

This module tests for standalone CCTV DVR video surveillance deployments specifically by MicroDigital, HIVISION, CTRing, and numerous other rebranded devices that are utilizing default vendor passwords. Additionally, this module has the ability to brute force user accounts. Such CCTV DVR video surveillance deployments support remote viewing through Central Management Software (CMS) via the CMS Web Client, an IE ActiveX control hosted over HTTP, or through Win32 or mobile CMS client software. By default, remote authentication is handled over port 5920/TCP with video streaming over 5921/TCP. After successful authentication over 5920/TCP this module will then attempt to determine if the IE ActiveX control is listening on the default HTTP port (80/TCP).

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

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(cctv_dvr_login) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(cctv_dvr_login) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(cctv_dvr_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>'
