The Common Vulnerability Scoring System (CVSS) is used to assess the severity of security vulnerabilities in computer systems. The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various metrics 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. The Temporal Score also takes into account changes over time with regard to the risk situation. The severity of the vulnerability discussed here is classified as “medium” according to the CVSS with a base score of 7.8.
