CVSS Score

cvss

The Common Vulnerability Scoring System (CVSS) object provides a way to capture the principal characteristics of a vulnerability and produce a numerical score reflecting its severity.

Attributes

Caption	Name	Type	Description
Base Score	`base_score`	Float	The CVSS base score. For example: `9.1`.
CVSS Depth	`depth`	String	The CVSS depth represents a depth of the equation used to calculate CVSS score. `Base`: Base (`BASE`) `Environmental`: Environmental (`ENVIRONMENTAL`) `Temporal`: Temporal (`TEMPORAL`)
Metrics	`metrics`	Metric[]	The Common Vulnerability Scoring System metrics. This attribute contains information on the CVE's impact. If the CVE has been analyzed, this attribute will contain any CVSSv2 or CVSSv3 information associated with the vulnerability. For example: `{ {"Access Vector", "Network"}, {"Access Complexity", "Low"}, ...}`.
Overall Score	`overall_score`	Float	The CVSS overall score, impacted by base, temporal, and environmental metrics. For example: `9.1`.
Raw Data	`raw_data`	JSON	Group:`context` The event data as received from the event source.
Record ID	`record_id`	String	Group:`primary` Unique identifier for the object
Severity	`severity`	String	The Common Vulnerability Scoring System (CVSS) Qualitative Severity Rating. A textual representation of the numeric score. CVSS v2.0 Low (0.0 – 3.9) Medium (4.0 – 6.9) High (7.0 – 10.0) CVSS v3.0 None (0.0) Low (0.1 - 3.9) Medium (4.0 - 6.9) High (7.0 - 8.9) Critical (9.0 - 10.0)
Source URL	`src_url`	URL String	Entity:`URL_STRING` The source URL for the CVSS score. For example: `https://nvd.nist.gov/vuln/detail/CVE-2021-44228`
Unmapped	`unmapped`	Unmapped[]	Data from the source that was not mapped into the schema.
Vector String	`vector_string`	String	The CVSS vector string is a text representation of a set of CVSS metrics. It is commonly used to record or transfer CVSS metric information in a concise form. For example: `3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H`.
Vendor Name	`vendor_name`	String	The vendor that provided the CVSS score. For example: `NVD, REDHAT` etc.
Version	`version`	String	The CVSS version. For example: `3.1`.
