The tool allows users to compute a standardized numerical score representing the severity of a software vulnerability based on the Common Vulnerability Scoring System version 4.0. It functions by inputting specific characteristics of a vulnerability, such as attack vector, attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact. The calculator then processes these inputs according to the CVSS 4.0 formula, generating a base score, which can be further refined by environmental and temporal metrics to provide a more complete assessment of the risk.
This scoring system is important for several reasons. It offers a standardized method for communicating the severity of vulnerabilities, enabling security professionals, system administrators, and software developers to prioritize remediation efforts effectively. It provides a common language, which facilitates clear communication across different organizations and sectors. Its evolution reflects a continuous effort to improve the accuracy and relevance of vulnerability scoring methodologies, leading to more informed security decisions.
