The Common Vulnerability Scoring System (CVSS) is used to assess the vulnerability of computer systems. The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various criteria in order to better prioritize countermeasures. The attributes “none”, “low”, “medium”, “high” and “critical” are used for the severity of a vulnerability. The base score assesses the prerequisites for an attack (including authentication, complexity, privileges, user interaction) and its consequences.
