A vulnerability scan of a web server that is exposed to the internet was recently completed. A security analyst is reviewing the resulting vector strings:Vulnerability 1: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L, Vulnerability 2: CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:H, Vulnerability 3: CVSS:3.0/AV:A/AC:H/PR:L/UI:R/S:U/C:L/I:H/A:L, Vulnerability 4: CVSS:3.0/AV:P/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:L.Which of the following vulnerabilities should be patched first?

Vulnerability 2 presents a CVSS score with a moderate confidentiality impact, low integrity impact, and high availability impact. Although it poses risks to data confidentiality, the lower severity compared to Vulnerability 1 prioritizes addressing the latter first to mitigate higher confidentiality threats.

Vulnerability 3's CVSS score indicates a low confidentiality impact, high integrity impact, and low availability impact. While data integrity is at risk, the lower impact on confidentiality compared to Vulnerability 1 implies that addressing Vulnerability 1 takes precedence to safeguard critical data confidentiality.

Vulnerability 4's CVSS score reveals high confidentiality impact, no integrity impact, and low availability impact. Despite sharing a high confidentiality impact with Vulnerability 1, the absence of integrity risks in Vulnerability 4 positions Vulnerability 1 as the primary concern for immediate patching to address data confidentiality vulnerabilities effectively.
