The following is a general overview of the enrichment process for a given CVE:
- Enrichment efforts begin with reviewing any reference material provided with the CVE record and assigns appropriate reference tags. This helps organize the various data sources to help researchers find the relevant information for their needs. Enrichment efforts also include manual searches of the internet to ensure that any other available and relevant information is used for the enrichment process. NVD enrichment efforts only use publicly available materials in the enrichment process.
- A common weakness enumeration (CWE) identifier is assigned that categorizes the vulnerability. NVD enrichment efforts use a subset of the full list of CWEs that best represents the distribution of specific types of vulnerabilities. This subset is known as the CWE-1003 view and was created through coordination with the MITRE CWE team.
- CVSS V3.1 exploitability and impact metrics are assigned based on publicly available information and the guidelines of the specification if a CVSS score has not already been assigned. If an existing score is noticed to not be supported by CVSS guidelines or publicly available information while performing other enrichment activities, an enrichment team member may choose to provide a score. Users of NVD data may also request the NVD to provide a score.
- A Common Platform Enumeration (CPE) Applicability Statement is associated with the vulnerability. The CPE match criteria are generated to identify potentially vulnerable software and/or hardware for the vulnerability. For example, an application may have several versions affected or must be running on a specific operating system to be vulnerable. Automated processes can reference match criteria within the applicability statements against the CPE dictionary to assist in identifying vulnerable products within an organizationâ(TM)s information system. Every effort is made to identify all vulnerable software, but gaps may exist and feedback is encouraged to improve this information.
- Enrichment effort results are given a quality assurance check by another experienced team member prior to being published to the website and data feeds.
