Appendix: About CVSS
The Common Vulnerability Scoring System (CVSS) is an open standard for communicating the characteristics and severity of software vulnerabilities. The Base score represents the intrinsic qualities of a vulnerability. The Temporal score reflects the characteristics of a vulnerability that change over time. The Environmental score is an additional score that can be used by CVSS, but is not supplied as it will differ for each customer. The Base score has a value ranging from 0 to 10. The Temporal score has the same range and is a modification of the Base score due to current temporary factors. The severity of the score can be summarized as follows:
0.1 – 3.9
4.0 – 6.9
9.0 – 10.0
A CVSS score is also represented as a vector string, a compressed textual representation of the values used to derive the score.
Detailed information about CVSS can be found at http://www.first.org/cvss.
