What is indicated by the Temporal CVSS ranking metric?

• A. The unique aspects of a vulnerability
• B. The stable characteristics of a vulnerability
• C. The changeable attributes of a vulnerability
• D. The presence of vulnerabilities in exploited environments

Answer: (C)

The Temporal CVSS (Common Vulnerability Scoring System) ranking metric reflects the changeable attributes of a vulnerability over time. This includes factors such as the availability of exploit code, the remediation level, and the report confidence. These aspects are not static; they can fluctuate as new information becomes available or as conditions in the environment change, making the Temporal metric crucial for understanding a vulnerability's risk profile in a dynamic context. For instance, if a new exploit for a vulnerability is discovered and made publicly available, the score may reflect an increased risk due to the change in the availability of exploits. Meanwhile, if a vendor releases a patch that mitigates the vulnerability, the remediation level may change, subsequently lowering the risk associated with it. This focus on changeable attributes helps organizations prioritize their response to vulnerabilities based on how their risk may evolve, which is not captured by the stable characteristics of a vulnerability or the unique aspects of a vulnerability. The presence of vulnerabilities in exploited environments, while important for understanding risk, pertains more to the operational aspect and does not directly relate to the changeability represented by the Temporal metric.
