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 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. With the temporal score, framework conditions that can change over time are taken into account in the evaluation. The severity of the vulnerability discussed here is rated as “medium” according to the CVSS with a base score of 7.6.
