Ruby Qualys API v2

A Ruby extension for interfacing with Qualys v2 API.

Introduction

I had the need to pull stats and details from Qualys automatically to collect and alert on metrics. Let's face it, in 2015, email alerts just don't cut it anymore.

Installation

Add this line to your application's Gemfile:

gem 'qualys', git: 'https://github.com/Cyberwatch/ruby-qualys.git'

And then execute:

$ bundle

Usage

Below you can find details on the configuration and usage of the Qualys API Client.

Configuration

Before utilizing the API, you must configure it. You can configure it with a block like below, or by passing in a Hash# or load a yaml file.

Qualys.configure do |config|
  config.username = @email
  config.password = @password
  config.api_base_uri = 'https://qualysapi.qualys.eu/api/2.0/fo/'
  config.proxy_uri = 'http://user:password@localhost:3128'
end

or configure using a yaml doc:

Qualys::Config.load!('config/qualys.yaml')

Login

Login before making other API calls:

Qualys::Auth.login

Getting Scans

You can easily get a list of all scans within your Qualys account by accessing the following methods:

scans = Qualys::Scans.all
  #-> [#<Qualys::Scan:0x007fad4c4645c8 @ref="scan/refid", @title="Scan Title", @type="Scheduled", @date="2015-04-15T12:02:12Z", @duration="01:51:38", @status="Finished", @target="ip ranges", @user="managing_user">...

You can get more details from each scan like:

scans = Qualys::Scans.all
puts scans.first.details
  #-> {"ip"=>"x.x.x.x", "dns"=>"mikemackintosh.com", "netbios"=>nil, "qid"=>86000, "result"=>"Server Version\tServer Banner\nnginx\tnginx", "protocol"=>"tcp", "port"=>"80", "ssl"=>"no", "fqdn"=>""}, 
  #   {"ip"=>"x.x.x.x", "dns"=>"mikemackintosh.com", "netbios"=>nil, "qid"=>86189, "result"=>"Number of web servers behind load balancer:\n2 - based on IP Identification values", "protocol"=>"tcp", "port"=>"80", "ssl"=>"no", "fqdn"=>""}, 
  #  {"ip"=>"x.x.x.x, "dns"=>"mikemackintosh.com", "netbios"=>nil, "qid"=>86001, "result"=>"Server Version\tServer Banner\nnginx\tnginx", "protocol"=>"tcp", "port"=>"443", "ssl"=>"no", "fqdn"=>""}

Set the URI

If your URL differs from the default, set it using:

Qualys::Api.base_uri = OTHER_PRODUCTION_ENDPOINT

Getting vulnerabilities

You can load the vulnerability detected by qualys for the hosts scanned by a specific scan if you don't specify any scan_ref, it prints all vulnerabilities detected by qualys so far for the logged user. Here an example printing some information on the vulnerabilities for the second scan of the logged user :

scan_ref = Qualys::Scans.all[1].ref
Qualys::Report.create(scan_ref).hosts.each{ |host|
  p "ip:#{ host.ip }"
  p "vulns : (#{ host.vulnerabilities.count })"
  host.vulnerabilities.each{ |vuln|
    p vuln.to_s
  }
}

Output :

"ip:12.34.156.89"
"vulns : (16)"
"qid_38173, SSL Certificate - Signature Verification Failed Vulnerability, severity : 2, cves: no cve"
"qid_38685, SSL Certificate - Invalid Maximum Validity Date Detected, severity : 2, cves: no cve"
