Given the output, the penetration tester should select the fileserver as the next target for testing, considering both CVSS and EPSS scores.

CVSS (Common Vulnerability Scoring System):

Purpose: CVSS provides a numerical score to represent the severity of vulnerabilities, helping to prioritize remediation efforts.

Higher Scores: Indicate more severe vulnerabilities.

EPSS (Exploit Prediction Scoring System):

Purpose: EPSS estimates the likelihood that a vulnerability will be exploited in the wild within the next 30 days.

Higher Scores: Indicate a higher likelihood of exploitation.

Evaluation:

hrdatabase: CVSS = 9.9, EPSS = 0.50

financesite: CVSS = 8.0, EPSS = 0.01

legaldatabase: CVSS = 8.2, EPSS = 0.60

fileserver: CVSS = 7.6, EPSS = 0.90

The fileserver has the highest EPSS score, indicating a high likelihood of exploitation, despite having a slightly lower CVSS score compared to hrdatabase and legaldatabase.

Pentest References:

Prioritization: Balancing between severity (CVSS) and exploitability (EPSS) is crucial for effective vulnerability management.

Risk Assessment: Evaluating both the impact and the likelihood of exploitation helps in making informed decisions about testing priorities.

By selecting the fileserver, which has a high EPSS score, the penetration tester focuses on a target that is more likely to be exploited, thereby addressing the most immediate risk.
