CVSS Calculator

CVSS Calculator is a Java library for calculating CVSSv2, CVSSv3, CVSSv3.1, and CVSSv4.0 scores and vectors, including support for base scores, impact scores, and exploitability scores.

Compiling

$ mvn clean package

Usage Example

// Performs a new calculation using CVSSv3
CvssV3 cvssV3 = new CvssV3()
    .attackVector(AttackVector.NETWORK)
    .attackComplexity(AttackComplexity.LOW)
    .privilegesRequired(PrivilegesRequired.HIGH)
    .userInteraction(UserInteraction.NONE)
    .scope(Scope.UNCHANGED)
    .confidentiality(CIA.HIGH)
    .integrity(CIA.HIGH)
    .availability(CIA.HIGH);

Score score = cvssV3.calculateScore();
// Parses an existing CVSS v2, v3, v3.1, or v4.0 vector
Cvss cvss = Cvss.fromVector(vector);
Score score = cvss.calculateScore();
// Performs a new calculation using CVSSv4.0
CvssV4 cvssV4 = new CvssV4()
    .attackVector(CvssV4.AttackVector.NETWORK)
    .attackComplexity(CvssV4.AttackComplexity.LOW)
    .attackRequirements(CvssV4.AttackRequirements.NONE)
    .privilegesRequired(CvssV4.PrivilegesRequired.HIGH)
    .userInteraction(CvssV4.UserInteraction.NONE)
    .confidentialityImpact(CvssV4.Impact.HIGH)
    .integrityImpact(CvssV4.Impact.HIGH)
    .availabilityImpact(CvssV4.Impact.HIGH)
    .subsequentConfidentiality(CvssV4.Impact.NONE)
    .subsequentIntegrity(CvssV4.Impact.NONE)
    .subsequentAvailability(CvssV4.Impact.NONE);

Score score = cvssV4.calculateScore();
