Metasploitable3

Metasploitable3 is a VM that is built from the ground up with a large amount of security vulnerabilities. It is intended to be used as a target for testing exploits with metasploit.

Metasploitable3 is released under a BSD-style license. See COPYING for more details.

Quick-start

To use the prebuilt images provided at https://app.vagrantup.com/rapid7/ create a new local metasploitable workspace:

Linux users:

mkdir metasploitable3-workspace
cd metasploitable3-workspace
curl -O https://raw.githubusercontent.com/rapid7/metasploitable3/master/Vagrantfile && vagrant up

Windows users:

mkdir metasploitable3-workspace
cd metasploitable3-workspace
Invoke-WebRequest -Uri "https://raw.githubusercontent.com/rapid7/metasploitable3/master/Vagrantfile" -OutFile "Vagrantfile"
vagrant up

Or clone this repository and build your own box.

Building Metasploitable 3

System Requirements:

  • OS capable of running all of the required applications listed below
  • VT-x/AMD-V Supported Processor recommended
  • 65 GB Available space on drive
  • 4.5 GB RAM

Requirements:

To build automatically:

    • On Linux/OSX run ./build.sh windows2008 to build the Windows box or ./build.sh ubuntu1404 to build the Linux box. If /tmp is small, use TMPDIR=/var/tmp ./build.sh ... to store temporary packer disk images under /var/tmp.
    • On Windows, open powershell terminal and run .\build.ps1 windows2008 to build the Windows box or .\build.ps1 ubuntu1404 to build the Linux box. If no option is passed to the script i.e. .\build.ps1, then both the boxes are built.
  1. If both the boxes were successfully built, run vagrant up to start both. To start any one VM, you can use:
    • vagrant up ub1404 : to start the Linux box
    • vagrant up win2k8 : to start the Windows box
  2. When this process completes, you should be able to open the VM within VirtualBox and login. The default credentials are U: vagrant and P: vagrant.

To build manually:

  1. Clone this repo and navigate to the main directory.
  2. Build the base VM image by running packer build --only=<provider> ./packer/templates/windows_2008_r2.json where <provider> is your preferred virtualization platform. Currently virtualbox-iso, qemu, and vmware-iso providers are supported. This will take a while the first time you run it since it has to download the OS installation ISO.
  3. After the base Vagrant box is created you need to add it to your Vagrant environment. This can be done with the command vagrant box add packer/builds/windows_2008_r2_*_0.1.0.box --name=rapid7/metasploitable3-win2k8.
  4. Use vagrant plugin install vagrant-reload to install the reload vagrant provisioner if you haven't already.
  5. To start the VM, run the command vagrant up win2k8. This will start up the VM and run all of the installation and configuration scripts necessary to set everything up. This takes about 10 minutes.
  6. Once this process completes, you can open up the VM within VirtualBox and login. The default credentials are:
    • Username: vagrant
    • Password: vagrant

ub1404 Development and Modification

Using Vagrant and a lightweight Ubuntu 14.04 vagrant cloud box image, you can quickly set up and customize ub1404 Metasploitable3 for development or customization. To do so, install Vagrant and a hypervisor such as VirtualBox, VMWare, or libvirt.

Install the relevant provider plugin:

# virtualbox
vagrant plugin install vagrant-vbguest

# libvirt
vagrant plugin install vagrant-libvirt

Then, navigate to the chef/dev/ub1404 directory in this repository. Examine the Vagrantfile there. Select a base box that supports your provider.

Metasploitable ub1404 uses the vagrant chef-solo provisioner. Configure the chef_solo block in the Vagrantfile with the metasploitable chef recipes that you desire -- you can browse them in the chef/cookbooks/metasploitable folder. Or, add or edit your own cookbook and/or recipes there.

From the chef/dev/ub1404 directory, you can run vagrant up to get a development virtual ub1404 instance. After the initial up build and provision, when you edit the chef runlist or when you edit a chef recipe, run vagrant rsync && vagrant provision from the same directory. For faster development, you can comment-out recipes that you do not need to rerun -- but even if they are all enabled, vagrant re-provisioning should not take longer than one or two minutes. Chef aims to be idempotent, so you can rerun this command often.

Consider taking a snapshot (e.g., vagrant snapshot save fresh) before modifying recipes, so that you can always return to an initial state (vagrant restore fresh). If you want a totally fresh snapshot, you can do the initialization with vagrant up --no-provision, then take a snapshot, followed by vagrant provision.
