Multiple vulnerabilities for Red Hat OpenShift – Risk: High
Risk level: 3 (high)
CVSS Base Score: 8,8
CVSS Temporal Score: 7,7
Remoteangriff: Ja
The Common Vulnerability Scoring System (CVSS) is used to assess the severity of vulnerabilities in computer systems. The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various metrics 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. The temporal score also takes changes over time in the danger situation into account. According to the CVSS, the threat of the current vulnerability is rated as “high” with a base score of 8.8.
