Common Vulnerability Scoring System Version 3.1 Calculator

The Common Vulnerability Scoring System (CVSS) is an open framework for communicating the characteristics and severity of software vulnerabilities by First which consists of three metric groups: Base, Temporal, and Environmental.

Base Score

Attack Vector (AV)

Attack Complexity (AC)

Privileges Required (PR)

User Interaction (UI)

Scope (S)

Confidentiality (C)

Integrity (I)

Availability (A)

Select values for all base metrics to generate score

Vector String - select values for all base metrics to generate a vector

Temporal Score

Exploit Code Maturity (E)

Remediation Level (RL)

Report Confidence (RC)

Select values for all base metrics to generate score

Environmental Score

Confidentiality Requirement (CR)

Integrity Requirement (IR)

Availability Requirement (AR)

Modified Attack Vector (MAV)

Modified Attack Complexity (MAC)

Modified Privileges Required (MPR)

Modified User Interaction (MUI)

Modified Scope (MS)

Modified Confidentiality (MC)
