A penetration tester needs to evaluate the order in which the next systems will be...

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.
