Do CVSS scores change?

Do CVSS scores change?

CVSS scores are composed of three sub metric groups – CVSS Base Metrics, CVSS Temporal Metrics, and CVSS Environmental Metrics. In most cases, the CVSS score reported in the NIST NVD is only the Base Score. Strictly speaking, the Base Score should not change over time, but that isn’t always the case.

What is a NIST score?

The NIST Score tool is a software tool that supports the development of data exchange standards based on the ISO 15000-5 Core Components standard . Score has been used in production by the Open Application Group standards organization and by several major manufacturing enterprises.

What is a high CVE score?

What is the Common Vulnerability Scoring System (CVSS)

How does the common vulnerability scoring system ( CVSS ) work?

The Common Vulnerability Scoring System (CVSS) provides a way to capture the principal characteristics of a vulnerability, and produce a numerical score reflecting its severity, as well as a textual representation of that score.

How to generate a CVSS v3.0 base score?

* – All base metrics are required to generate a base score. The CVSS v3.0 equations are defined below. The Base Score is a function of the Impact and Exploitability sub score equations. Where the Base score is defined as,

How is the environmental score used in CVSS?

When the environmental score is computed, the vulnerability becomes contextual to each organization, and helps provide a better understanding of the risk posed by this vulnerability to the organization. This document describes the official CVSS v3.0 specification. 1.1. Metrics

What’s the difference between integrity and exploitability in CVSS?

The difference is in the rating of the impact: Integrity = High or Integrity = Low, resulting in a combined score of either 7.5 or 5.3 (in CVSS Version 3.0). In either case, both scores earn the exploitability rating of 10, because the issue may be exploited over a network without authentication.
