Question

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: Which of the following vulnerabilities should be patched first?

Options

  • AVulnerability 1
  • BVulnerability 2
  • CVulnerability 3
  • DVulnerability 4

Explanation

The question asks which vulnerability to patch first from a list of vector strings, implying a need to prioritize based on severity and potential impact to an internet-exposed web server.

Common mistakes.

  • B. Vulnerability 2 would likely have a lower CVSS score compared to Vulnerability 1, indicating less severe impact or harder exploitability, thus making it a lower priority for immediate patching.
  • C. Vulnerability 3 would likely have a lower CVSS score compared to Vulnerability 1, indicating less severe impact or harder exploitability, thus making it a lower priority for immediate patching.
  • D. Vulnerability 4 would likely have a lower CVSS score compared to Vulnerability 1, indicating less severe impact or harder exploitability, thus making it a lower priority for immediate patching.
