The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various criteria in order to create a priority list for taking countermeasures. The attributes “none”, “low”, “medium”, “high” and “critical” are used to determine the severity levels of a vulnerability. The Base Score evaluates the requirements for an attack (including authentication, complexity, privileges, user interaction) and its consequences.
