What is CVSS?
CVSS (Common Vulnerability Scoring System) is an open standard for assessing the severity of security vulnerabilities. It helps organizations prioritize their responses to vulnerabilities based on their potential impact.
CVSS Formula and Mathematical Explanation
The CVSS score is calculated as the sum of the base score, temporal score, and environmental score. Each score ranges from 0 to 10, with higher scores indicating more severe vulnerabilities.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Base Score | Measures the intrinsic characteristics of a vulnerability. | 0-10 | 0-10 |
| Temporal Score | Measures the vulnerability’s characteristics that change over time. | 0-10 | 0-10 |
| Environmental Score | Measures the vulnerability’s characteristics that are specific to the affected organization. | 0-10 | 0-10 |
Practical Examples
Example 1: Critical Vulnerability
Base Score: 9.8, Temporal Score: 0, Environmental Score: 0.5
CVSS Score: 10.3
Interpretation: This is a critical vulnerability that requires immediate attention.
Example 2: Low Severity Vulnerability
Base Score: 3.1, Temporal Score: 0, Environmental Score: 0
CVSS Score: 3.1
Interpretation: This vulnerability has low severity and can be addressed at a later time.

Key Factors That Affect CVSS Results
Several factors can affect the CVSS score, including the vulnerability’s exploitability, remediation level, and report confidence.
Frequently Asked Questions
What does a CVSS score of 10 mean?
