Join Mike Chapple for an in-depth discussion in this video Interpreting CVSS scores, part of CompTIA CySA+ (CS0-002) Cert Prep: 2 Vulnerability Management.
- [Instructor] Once we've assigned ratings … to the individual CVSS metrics, … we can combine them to determine the CVSS-based score. … I'll show you an example of that in just a moment. … First, let's take a look at a vulnerability report … from a server where Nessus detected support … for the outdated SSL protocol. … Here's the CVSS version three vector for this vulnerability. … It looks like just a long string of characters, … but now we have the information that we need … to make sense of it. … Let's go ahead and interpret … this CVSS string piece by piece. … AV:N means that the access vector is network. … An attacker can exploit this vulnerability … remotely over the network. … AC:L means that the attack complexity is low. … It would be easy to exploit this vulnerability. … PR:N means that there are no special privileges … required to execute the vulnerability. … The attacker does not need an existing user … or administrator account on the target system. … UI:N means that no user interaction is required. …
