Is Patch Prioritization Based on CVSS Scores Alone Misleading?

CVSS scores are widely recognized as the industry standard for assessing vulnerability risk. But is it enough to prioritize patching based solely on CVSS scores. Let’s talk about it.

Let’s start with the basics. CVSS scores provide a standardized framework for assessing vulnerability risks. They’re universally accepted and give IT teams a clear, objective way to prioritize patches. It’s efficient and straightforward.

That’s true but it’s not the full picture. CVSS scores lacks context. A high CVSS score doesn’t necessarily mean the vulnerability poses a significant risk in every environment. Misprioritizing based on scores alone can waste resources.

Sure, but CVSS gives a baseline—a foundation to build on. Without it, how do you even begin to assess which vulnerabilities are critical?

[Samhith]

I’m not saying throw it out, but relying solely on CVSS can be misleading. For example, take a high-severity vulnerability in a system that’s isolated and heavily firewalled. It’s less urgent than a medium-severity issue in a core business application.

[Srivatsa]

Let’s not forget that CVSS includes metrics like exploitability. It’s not just about severity; it gives an indication of how easy a vulnerability is to exploit. That’s a critical factor for prioritization.
