How to Use This Calculator

Set Attack Vector (0=Network, 1=Adjacent, 2=Local, 3=Physical) -- network-accessible vulnerabilities score highest.
Set Attack Complexity (0=Low, 1=High), Privileges Required (0=None, 1=Low, 2=High), and User Interaction (0=None, 1=Required).
Set Scope (0=Unchanged, 1=Changed) and Confidentiality, Integrity, and Availability Impact.
Review CVSS Base Score (0-10), Exploitability score, Impact score, and severity rating.
Prioritize Critical (9.0-10) and High (7.0-8.9) findings for immediate remediation.
