Exam CS0-003 topic 1 question 423 discussion

AV = N Firewall = Vulnerable System Network-connected devices = Subsequent Systems If the script or vulnerability leads to data being altered on those networked devices, then: VI (Vulnerable System Integrity) = probably None or Low SI (Subsequent System Integrity) = High

AC = N Firewall = Vulnerable System Network-connected devices = Subsequent Systems If the script or vulnerability leads to data being altered on those networked devices, then: VI (Vulnerable System Integrity) = probably None or Low SI (Subsequent System Integrity) = High

The security analyst is looking for a CVSS v4.0 vector that represents a vulnerability meeting two main criteria for testing their script: It should be a vulnerability that a script filtering firewall vulnerabilities might detect. This suggests a vulnerability that is network-facing or related to network devices. The Attack Vector (AV) metric is important here. Exploiting the vulnerability should impact the integrity of data hosted on devices connected to networks. In CVSS v4.0, the impact on other systems connected to the vulnerable one is captured by the Subsequent System Impact metrics, specifically Subsequent System Integrity (SI). This should be High (H). Therefore; Option B is the only vector that describes a network-exploitable vulnerability with a high impact on the integrity of subsequent systems, which directly matches the requirements for a true positive for the analyst's script.
