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 criteria in order to create a list of priorities for initiating countermeasures based on this. 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. With the temporal score, framework conditions that change over time are included in the evaluation. The risk of the current vulnerability is classified as “high” according to the CVSS with a base score of 8.8.
