Risk level: 3 (medium)
CVSS Base Score: 5,5
CVSS Temporal Score: 5,0
Remote attack: No
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 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. The temporal score also takes changes over time in the danger situation into account. The severity of the current vulnerability is classified as “medium” according to the CVSS with a base score of 5.5.
