Actual exam question for Eccouncil's 312-50 exam
Question #: 80
Topic #: 7
[All 312-50 Questions]

A cybersecurity analyst in an organization is using the Common Vulnerability Scoring System to assess and prioritize identified vulnerabilities in their IT infrastructure. They encountered a vulnerability with a base metric score of 7, a temporal metric score of 8, and an environmental metric score of 5. Which statement best describes this scenario?

Suggested Answer: D

The Common Vulnerability Scoring System (CVSS) is a method used to supply a qualitative measure of severity for a vulnerability. CVSS consists of three metric groups: Base, Temporal, and Environmental. The Base metrics produce a score ranging from 0 to 10, which can then be modified by scoring the Temporal and Environmental metrics.A vector string represents the values of all the metrics as a block of text1

The Base metrics measure the intrinsic characteristics of a vulnerability, such as the attack vector, the attack complexity, the required privileges, the user interaction, the scope, and the impact on confidentiality, integrity, and availability.The Base score reflects the severity of a vulnerability assuming that there is no temporal information or context available1

The Temporal metrics measure the characteristics of a vulnerability that change over time, such as the exploit code maturity, the remediation level, and the report confidence.The Temporal score reflects the current state of a vulnerability and its likelihood of being exploited1

The Environmental metrics measure the characteristics of a vulnerability that depend on a specific implementation or environment, such as the security requirements, the modified base metrics, and the collateral damage potential.The Environmental score reflects the impact of a vulnerability on a particular organization or system1

In this scenario, the vulnerability has a Base score of 7, a Temporal score of 8, and an Environmental score of 5. This means that:

The vulnerability has a high severity based on its intrinsic characteristics, such as the attack vector, the attack complexity, the required privileges, the user interaction, the scope, and the impact on confidentiality, integrity, and availability.A Base score of 7 corresponds to a high severity rating according to the CVSS v3.0 specification1

The vulnerability has an increasing likelihood of exploitability over time based on its current state, such as the exploit code maturity, the remediation level, and the report confidence.A Temporal score of 8 is higher than the Base score of 7, which indicates that the vulnerability is more likely to be exploited as time passes1

The vulnerability has a medium impact on the specific environment or implementation based on the security requirements, the modified base metrics, and the collateral damage potential.An Environmental score of 5 is lower than the Base score of 7, which indicates that the vulnerability is less impactful in the particular context of the organization or system1

Therefore, the statement that best describes this scenario is: The vulnerability has an overall high severity, the likelihood of exploitability is increasing over time, and it has a medium impact in their specific environment.

I think the vulnerability is not that severe, so I would go with C.
