Selected Answer: C
To determine which CVE to prioritize, we analyze the CVSS (Common Vulnerability Scoring System) vector string for each vulnerability. Higher severity vulnerabilities should be prioritized first. Explanation of the CVSS Vector Components: AV (Attack Vector): N (Network): The vulnerability is exploitable over a network. (Most critical) A (Adjacent): Exploitable in the same network segment. L (Local): Requires local access to exploit. P (Physical): Requires physical access to exploit. PR (Privileges Required): N (None): No privileges are required. (Most critical) L (Low): Low privileges are required. H (High): High privileges are required. AC (Attack Complexity): L (Low): Exploiting is straightforward. (Most critical) H (High): Exploiting is complex. UI (User Interaction): N (None): No user interaction is required. (Most critical) R (Required): User interaction is required. So, for CVE-3: AV:N/PR:L/AC:L/UI:N Exploitable over the network. Low privileges required. Low complexity, no user interaction. Severity: High.
