Purpose: The purpose of this script is to update the CVE, CPE, and CCE databases. Script will sleep for 3 seconds between actions to allow you review the results.
Usage: php update_db.php [--cpe] [--cve] [--nvd] [--nasl] [--stig] [-u={URL}] [--do] [--po] [-h|--help] [--debug] [--exclude="ex1"]
--cpe To download and update the CPE catalog
--cve To download and update the CVE catalog using Mitre's database
--nvd To download and update the CVE catalog using the National Vulnerability Database (NVD) JSON library
--nasl To download OpenVAS NVT library and update NASL files
You can also extract *.nasl files from the Nessus library to $tmp/nessus_plugins and it will include these in the update
--stig To download and update the STIG library
--do To download the files only...do not call the parsers will overwrite any existing files
--po To parse the downloaded files only, do not download
--exclude="ex1" Insert a valid regex expression (properly escaped) to exclude specific STIGs from parsing (no '/' necessary)
--extract Used so script will download and extract files from archive and stop processing
-u={url} Used only for STIGs because sometimes DISA will use a non-standard link which makes it difficult to download the file.
-h|--help This screen
--debug To print verbose debugging messages to the console
