Search for Common Platform Enumeration (CPE) strings using software names and titles.

cpe_search

Search for Common Platform Enumeration (CPE) strings using software names and titles.

About

cpe_search can be used to search for Common Platform Enumeration (CPE) strings using software names and titles. For example, if some tool discovered a web server running Apache 2.4.39, you can use this tool to easily and quickly retrieve the corresponding CPE 2.3 string cpe:2.3:a:apache:http_server:2.4.39:*:*:*:*:*:*:*. Thereafter, the retrieved CPE string can be used to accurately search for vulnerabilities, e.g. via the Online NVD or the search_vulns tool.

Installation

You can install cpe_search via pip directly:

pip3 install cpe_search

You can also clone this repository and run:

pip3 install .

Note that to use cpe_search, a local database containing all available CPEs is required. You can download a prebuilt version from cpe_search's GitHub releases, which also happens automatically during the first use:

cpe_search -d

You can also have cpe_search build the database itself, based on all available CPEs from the NVD's official API:

cpe_search -u -k "<YOUR_NVD_API_KEY>"

An NVD API key is optional, but speeds up the building process - and it's free. Building the database yourself typically takes a couple of minutes, since data for subsequent searches is precomputed as well and put into the local database. You can also set up and provide a configuration file, see config.json.

Usage

cpe_search's usage information is shown in the following:

usage: cpe_search [-h] [-u] [-k API_KEY] [-n NUMBER] [-q QUERY] [-v] [-V] [-d] [-c CONFIG]

Search for CPEs using software names and titles -- Created by Dustin Born (ra1nb0rn)

options:
  -h, --help            show this help message and exit
  -u, --update          Update the local CPE database
  -k API_KEY, --api-key API_KEY
                        NVD API key to use for updating the local CPE dictionary
  -n NUMBER, --number NUMBER
                        The number of CPEs to show in the similarity overview (default: 3)
  -q QUERY, --query QUERY
                        A query, i.e. textual software name / title like 'Apache 2.4.39' or 'Wordpress 5.7.2'
  -v, --verbose         Be verbose and print status information
  -V, --version         Print the version of cpe_search
  -d, --download-database
                        Download cpe_search database from latest GitHub release
  -c CONFIG, --config CONFIG
                        A config file to use (default: config.json)

Note that when querying software with -q you have to put the software information in quotes if it contains any spaces. Also, you can use -q multiple times to make multiple queries at once. Moreover, the output can be piped to be directly useable with other tools. Here are some examples:

• Query Sudo 1.8.2 to retrieve its CPE 2.3 string:

  $ cpe_search -q "Sudo 1.8.2"
  cpe:2.3:a:sudo_project:sudo:1.8.2:*:*:*:*:*:*:*
  [('cpe:2.3:a:sudo_project:sudo:1.8.2:*:*:*:*:*:*:*', 0.8660254037844385),
   ('cpe:2.3:a:sudo_project:sudo:1.3.0:*:*:*:*:*:*:*', 0.5773502691896256),
   ('cpe:2.3:a:cryptography.io:cryptography:1.8.2:*:*:*:*:*:*:*',
    0.4714045207910316)]
  

• Make a query and pipe the retrieved CPE to another tool:

  $ cpe_search -q "Windows 10 1809" | xargs echo
  cpe:2.3:o:microsoft:windows_10:1809:*:*:*:*:*:*:*
  

• Make two queries at once:

  $ cpe_search -q "Apache 2.4.39" -q "Wordpress 5.7.2"
  cpe:2.3:a:apache:http_server:2.4.39:*:*:*:*:*:*:*
  [('cpe:2.3:a:apache:http_server:2.4.39:*:*:*:*:*:*:*', 0.6666664603674289),
  ('cpe:2.3:a:apache:apache-airflow-providers-apache-spark:-:*:*:*:*:*:*:*',
    0.600000153741923),
  ('cpe:2.3:a:apache:apache-airflow-providers-apache-hive:-:*:*:*:*:*:*:*',
    0.600000153741923)]
  
  cpe:2.3:a:wordpress:wordpress:5.7.2:*:*:*:*:*:*:*
  [('cpe:2.3:a:wordpress:wordpress:5.7.2:*:*:*:*:*:*:*', 0.9805804786431419),
  ('cpe:2.3:a:wordpress:wordpress:-:*:*:*:*:*:*:*', 0.7071067811865475),
  ('cpe:2.3:a:adenion:blog2social:5.7.2:*:*:*:*:wordpress:*:*',
    0.6859944446591075)]
