The OVAL analyzer falsely assumes that any vulnerabilities detected on a
host only come from OVAL. However, it is possible that NVD detects
vulnerabilities on these hosts even though it excludes software from
deb_packages and rpm_packages. For example, a python package twisted
v22.20 has a vulnerability CVE-2022-39348 detected by NVD. The OVAL
analyzer would delete this vulnerability, and it would be re-inserted by
the NVD scanner on the next run. This creates a loop.
The fix is to only delete vulnerabilities that are actually detected
using OVAL. We already store this in the source column in the
software_cve table.
Feature: Improve our capability to detect vulnerable software on Ubuntu hosts
To improve the capability of detecting vulnerable software on Ubuntu, we are now using OVAL definitions to detect vulnerable software on Ubuntu hosts. If data sync is enabled (disable_data_sync=false) OVAL definitions are automatically kept up to date (they are 'refreshed' once per day) - there's also the option to manually download the OVAL definitions using the 'fleetctl vulnerability-data-stream' command. Downloaded definitions are then parsed into an intermediary format and then used to identify vulnerable software on Ubuntu hosts. Finally, any 'recent' detected vulnerabilities are sent to any third-party integrations.
