CVSS and DREAD calculators

CVSS score calculator

Dradis now supports CVSSv3, CVSSv3.1, and CVSSv4. Our Common Vulnerability Scoring System Calculator is heavily inspired by FIRST.

The Dradis CVSS score calculator is included as a tab when browsing individual Issues. Click on the tab to access the calculator and edit its values. You can select v3.0, v3.1, or v4.0 of the CVSS Calculator with the toggle in the top right.

Alternatively, from the projects page, you can navigate to Tools > Risk Calculators - CVSS in the header to access the instance-wide Dradis CVSS score calculator.

Then, copy/paste the output in the right hand sidebar into the corresponding Issue in your Dradis project or IssueLibrary entry.

CVSSv4

Select the correct values for:

• Base: Attack Vector, Attack Complexity, Attack Requirements, Privileges Required, User Interaction, Vulnerable System Confidentiality, Vulnerable System Integrity, Vulnerable System Availability, Subsequent System Confidentiality, Subsequent System Integrity, Subsequent System Availability

• Supplemental: Safety, Automatable, Recovery, Value Density, Vulnerability Response Effort, Provider Urgency

• Environmental: Modified Attack Vector, Modified Attack Complexity, Modified Attack Requirements, Modified Privileges Required, Modified User Interaction, Modified Vulnerable System Confidentiality, Modified Vulnerable System Integrity, Modified Vulnerable System Availability, Modified Subsequent System Confidentiality, Modified Subsequent System Integrity, Modified Subsequent System Availability, Confidentiality Requirements, Integrity Requirements, Availability Requirements

• Threat: Exploit Maturity

Then, click the "Update Issue" button to update the corresponding Issue in your Dradis project with the data from the calculator.

Note that the calculator uses the CVSSv4.BaseVector field to pre-populate the form. If you later edit your Issue manually and change some of the calculator values, other items such as CVSS score and Severity will not update accordingly. If you change the CVSSv4.BaseVector field, the changes should be reflected across all relevant fields.

CVSSv3 and CVSSv3.1

Select the correct values for:

• Base: Attack Vector, Attack Complexity, Privileges Required, User Interaction, Scope, Confidentiality, Integrity, Availability.

• Temporal: Exploit Code Maturity, Remediation Level, Report Confidence

• Environmental: Confidentiality Requirement, Integrity Requirement, Availability Requirement, Modified Attack Vector, Modified Attack Complexity, Modified Privileges Required, Modified User Interaction, Modified Scope, Modified Confidentiality, Modified Integrity, Modified Availability

Then, click the "Update Issue" button to update the corresponding Issue in your Dradis project with the data from the calculator.

Note that the calculator uses the CVSSv3.Vector field to pre-populate the form. If you later edit your Issue manually and change some of the calculator values, other items such as CVSS score and Severity will not update accordingly. If you change the CVSSv3.Vector field, the changes should be reflected across all relevant fields.

DREAD score calculator

DREAD stands for (D)amage, (R)eproducibility, (E)xploitability, (A)ffected users, (D)iscoverability and is a common risk assessment model introduced by Microsoft.

You can add a DREAD rating to an existing issue by navigating to the DREAD tab in the issue and clicking Edit to access the Dradis DREAD score calculator.

Select the correct values for Damage Potential, Affected users or systems, Reproducibility, Exploitability, and Discoverability.

Alternatively, from the projects page, you can navigate to Tools > Risk Calculators - DREAD in the header to access the instance-wide Dradis DREAD score calculator.

Then, copy/paste the output in the right hand sidebar into the corresponding Issue in your Dradis project or IssueLibrary entry.

Disabling the calculators

Want to remove the calculators from view to de-clutter your workspace? Go to Configuration, then Configure plugins, and you have the option to disable either or both of the calculators by setting their value of show to 0.
