A security analyst reviews the latest vulnerability scans and observes there are vulnerabilities with similar CVSSv3 scores but different base score metrics. Which of the following attack vectors should the analyst remediate first?
AV:N (Network): The vulnerability is exploited remotely, and an attacker does not require any access to the target system. This often involves attacks over a network.
Generally speaking, vulnerabilities that are exploitable over the network (AV:N) are often considered the most urgent to remediate because they can be exploited by any attacker who can reach the system over the network.
So, in this case, the analyst should prioritize remediating the vulnerability with the vector CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H (Option C), as it can be exploited from the network and therefore poses a higher risk of being exploited by a remote attacker.
When reviewing vulnerabilities with similar CVSSv3 scores, it's essential to consider the attack vectors and the potential impact on the organization.
Looking at all the values, the only one that changes is AV (Attack Vector).
According to criticality, the order would be as follows: C, B, D, A
The security analyst should focus more on an attack coming from the Network (C). The other options (A,B,D) require the vulnerability to be exploited within the internal network.
