# Command Line Programming - [RedHat Package Auditor](https://git.mcdevitt.tech/bpmcdevitt/misc_rbtools/-/tree/master/security_tools/redhat_tools)
|
||||||
|
I am working on a project where I am looking into vulnerabilities for Redhat
|
||||||
|
and CentOS systems. Throughout my time as a sysadmin I have always been a huge fan of command-line
|
||||||
|
programs. This is one of the programs that I hacked together to make my job
|
||||||
|
easier.
|
||||||
|
|
||||||
|
# Making my life easier
|
||||||
|
|
||||||
|
For a project I am working on, I am having to compare operating system vendor data against NVD data and have
|
||||||
|
been working in a spreadsheet initially to record the results. I am looking to see if NVD has captured correct
|
||||||
|
CPE data from the operating system vendors source. To start I was manually
|
||||||
|
looking at CVE/Advisory postings from Redhat and comparing with what was on
|
||||||
|
NVDs page for the given CVE. This grew tediuous rather quickly after I got
|
||||||
|
through a handful of CVEs. I needed to write a tool that would query Redhat's
|
||||||
|
API and give me all the needed info on that CVE. My first step was to see
|
||||||
|
if there was anything available that could do this quickly. After
|
||||||
|
looking online and finding old, outdated programs, I thought it would be quicker if I hacked together something.
|
||||||
|
|
||||||
|
I am a big linux nerd and have always loved using different command-line
|
||||||
|
programs. I have been using it for over 5 years now and I am always stumbling
|
||||||
|
upon new command-line driven programs. Writing command-line programs is fun and
|
||||||
|
this was an opportunity to write a new one.
|
||||||
|
|
||||||
|
This program will query Redhats Security API and spit back CVE data. I
|
||||||
|
have taken some of the examples from the README document that is linked here
|
||||||
|
with the source code.

--cve
|

--cves-from-file
|

### rpm-to-cve.xml
|
||||||
|
Redhats Security API also posts a mapping of RPM packages to CVEs in a
|
||||||
|
parseable XML file. This file can be downloaded [here](https://www.redhat.com/security/data/metrics/rpm-to-cve.xml). This commandline program can also
|
||||||
|
download a fresh XML file locally using the --refresh option.
|
||||||
|
|
||||||
|
{% highlight bash %}
|
||||||
|
./rpm_pkg_audit.rb --refresh
|
||||||
|
{% endhighlight %}
|
||||||
|
|
||||||
|
I run this as a sanity check to make sure the cmd finished downloading the file succesfully
|
||||||
|
{% highlight bash %}
|
||||||
|
echo $?
|
||||||
|
0
|
||||||
|
{% endhighlight %}
|
||||||
|
|
||||||
|
We can search for packages listed in this xml file by passing the --list option
|
||||||
|
and piping to a standard unix search tool like grep
|
||||||
|
|
||||||
|
{% highlight bash %}
|
||||||
|
./rpm_pkg_audit.rb --list | grep ^kernel
|
||||||
|
{%endhighlight%}
|
||||||
|
|
||||||
|
We can query packages in this xml file by querying the exact package name
|
||||||
|
{% highlight bash %}
|
||||||
|
./rpm_pkg_audit.rb --xmlpkg kernel-0:2.6.9-55.EL
|
||||||

### Query Redhat API For a package name
|
||||||
|
|
||||||
|
We can query the Redhat security API for a specific pkg by querying the BASE
|
||||||
|
pkg name. In this example we query the API and send bash as a param.

### Get the program!
|
||||||
|
I hope somebody can make use of this program for easier system administration
|
||||||
|
and security auditing purposes. I encourage all rhel/centos security admins to
|
||||||
|
make use of it if you would like better insight into CVE data from the vendor
|
||||||
|
source. You should be able to make use of the program
|
||||||
|
by cloning my misc_rbtools directory from my Gitlab. I will be expanding this
|
||||||
|
into its own Ruby gem in the coming days so please check back on this post. I
|
||||||
|
will update the link to the Ruby Gem page once it has been ported to a Gem!
|
||||||
|
|
||||||
|
{%highlight bash %}
|
||||||
|
|
||||||
|
git clone https://git.mcdevitt.tech/bpmcdevitt/misc_rbtools.git
|
||||||
|
Cloning into 'misc_rbtools'...

# Problem:
|
||||||
|
I needed to group severity of CVEs for a project I am working on into low,
|
||||||
|
medium, and high ranges. We have a risk score value between 0-100 that we can use to
|
||||||
|
categorize each CVE into a range.
|
||||||
|
|
||||||
|
<br>
|
||||||
|
|
||||||
|
# Solution:
|
||||||
|
We use the pandas library because it has some methods already written that allow
|
||||||
|
us to read a csv file and apply our severity function to the data on each row
|
||||||
|
in our csv file.
|
||||||
|
|
||||||
|
We can use the apply() function to do this with a lambda. We can define a new
|
||||||
|
column this way and it will write out the newly computed data to its own column
|
||||||
|
at the end of our file.

# WPScan Wordpress Vulnerability Database
|
||||||
|
## The data:
|
||||||
|
The WPScan team is a CNA. A [CVE Numbering
|
||||||
|
Authority](https://www.cve.org/ProgramOrganization/CNAs). A CNA basically gives the
|
||||||
|
authority to submit vulnerabilities in a piece of software (or hardware) to a particular vendor. The WPScan team finds many vulnerabilities in wordpress installs
|
||||||
|
all across the internet. Any researcher can submit a vulnerability at the
|
||||||
|
following [url](https://wpscan.com/submit).
|
||||||
|
|
||||||
|
For easier insight into the vulnerability data that they house, they have an [API](https://wpscan.com/docs/api/v3/) that can be
|
||||||
|
queried. I wrote a docker container that has shellscript wrapper that will query for
|
||||||
|
vulnerable plugins, themes, and wordpress core versions. I hope it can be
|
||||||
|
useful for somebody else that wants quick insight into the data this database
|
||||||
|
houses.
|
||||||
|
|
||||||
|
You will need to create an API token on the [wpscan](https://wpscan.com) website. They will allow you
|
||||||
|
25 free API calls per day on the free plan. That is more than enough for my
|
||||||
|
hobbyist usage with this program. You can find the source code at my gitlab
|
||||||
|
[here](https://git.mcdevitt.tech/bpmcdevitt/docker_wordpress_scanner).
|
||||||
|
|
||||||
|
Here is an example of the usage and querying for the navz-photo-gallery plugin:
|
||||||
|
|
||||||
|
```
|
||||||
|
docker run --env-file .env wp_checker --plugin 'navz-photo-gallery'

# cve.org CNA Security Advisories
|
||||||
|
## The data:
|
||||||
|
The website hosted at cve.org has recently been revamped. They host the source
|
||||||
|
code for the site at the following
|
||||||
|
[url](https://github.com/CVEProject/cve-website).
|
||||||
|
|
||||||
|
I wanted to know the organization names of each CNA and if possible, where they post their
|
||||||
|
vendor security advisories. I was looking for a URL to each advisory for each
|
||||||
|
vendor. This is so I can look into what
|
||||||
|
the actual vendor is saying when they are being notified of security
|
||||||
|
vulnerabilities. To obtain this infromation, we can look through the source
|
||||||
|
code used in the CVE Project website.
|
||||||
|
|
||||||
|
On the website itself if you search the 'List of
|
||||||
|
Partners' found [here](https://www.cve.org/PartnerInformation/ListofPartners)
|
||||||
|
you will find a hyperlink to a sub page for each organization name. As of writing this post,
|
||||||
|
there are 211 partners.
|
||||||
|
|
||||||
|
An example of one of the organization names page looks looks like this.
|

Notice the 'View Advisories' link here under the Security Advisories section.
|
||||||
|
|
||||||
|
{:class="img-responsive"} This is what I was looking for.
|
||||||
|
|
||||||
|
|
||||||
|
It really is nice that they host the source code to their website in the open.
|
||||||
|
Because of this, I can quickly pull this information that I want by writing a
|
||||||
|
little bit of code. It's just your standard GET request and parse a JSON file.
|
||||||
|
I like Ruby and both Python but I have been using Ruby longer, so I use that
|
||||||
|
more for pulling data quickly like the JSON data we are working with today. You
|
||||||
|
can find a [JSON
|
||||||
|
file](https://github.com/CVEProject/cve-website/blob/dev/src/assets/data/CNAsList.json) that the website uses to load the CNA information. We can write code that downloads this json file and parses it...like this!
|
||||||
|
|
||||||
|
```
|
||||||
|
#!/usr/bin/env ruby
|
||||||
|
# outputs the list of CNA organizationNames and the securityAdvisory urls from the json file here:
|
||||||
|
# https://raw.githubusercontent.com/CVEProject/cve-website/dev/src/assets/data/CNAsList.json
|
||||||
|
|
||||||
|
require 'json'
|
||||||
|
require 'rest-client'
|
||||||
|
|
||||||
|
class CnaSecurityAdvisories
|
||||||
|
attr_accessor :url
|
||||||
|
def initialize
|
||||||
|
@url = 'https://raw.githubusercontent.com/CVEProject/cve-website/dev/src/assets/data/CNAsList.json'
|
||||||
|
end
|
||||||
|
|
||||||
|
def send_request_rest
|
||||||
|
RestClient::Request.execute(
|
||||||
|
method: :get,
|
||||||
|
url: url
|
||||||
|
)
|
||||||
|
end
|
||||||
|
|
||||||
|
def parse_res(response)
|
||||||
|
JSON.parse(response.body)
|
||||||
|
end
|
||||||
|
|
||||||
|
def get_json
|
||||||
|
res = send_request_rest
|
||||||
|
if res.code == 200
|
||||||
|
parse_res(res)
|
||||||
|
else
|
||||||
|
"HTTP Status: #{res.code}"
|
||||||
|
end
|
||||||
|
end
|
||||||
|
|
||||||
|
def perform
|
||||||
|
json = get_json
|
||||||
|
json.map do |d|
|
||||||
|
org_name = d.dig('organizationName')
|
||||||
|
security_advisories = d.dig('securityAdvisories')
|
||||||
|
security_advisory_urls = security_advisories.dig('advisories').map { |adv| adv.dig('url') }
|
||||||
|
{ orgName: org_name, security_advisories_urls: security_advisory_urls }
|
||||||
|
end
|
||||||
|
end
|
||||||
|
end
|
||||||
|
```
|
||||||
|
|
||||||
|
I usually will pull out pry and load the class in the console and run it like this to export the data to a new json file.
|
||||||
|
|
||||||
|
```
|
||||||
|
[3] pry(main)> data = CnaSecurityAdvisories.new.perform
|
||||||
|
[4] pry(main)> File.write('/home/booboy/cna_security_advisory_urls.json', data.to_json)
|
||||||
|
=> 25298
|
||||||
|
```
|
||||||
|
|
||||||
|
I have hosted this code at my gitlab.
