IBM WebSphere Application Server Security Advisory – Risk: Medium
Risk level: 3 (medium)
CVSS Base Score: 7,5
CVSS Temporal Score: 6,5
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. With the temporal score, framework conditions that can change over time are taken into account in the evaluation. According to the CVSS, the risk of the current vulnerability is assessed as “medium” with a base score of 7.5.
