SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Security teams often drown in scanner output where every finding looks urgent. This Skill provides a structured methodology for scoring vulnerabilities with CVSS v4.0 and combining those scores with threat intelligence and asset context so remediation effort goes to the vulnerabilities that actually matter.

Core Features & Use Cases

  • CVSS v4.0 Scoring Guidance: Covers all metric groups (Base, Threat, Environmental, Supplemental), vector string construction, and severity rating bands, with worked examples like CVE-2024-3094.
  • Multi-Factor Prioritization: Blends CVSS base score, EPSS probability, CISA KEV listing, asset criticality, and network exposure into a weighted prioritization matrix.
  • Remediation SLA Definition: Maps priority tiers (P1–P5) to concrete remediation timelines from 24 hours to 90 days.
  • Use Case: Given a fresh vulnerability scan with hundreds of CVEs, apply this Skill to score each finding, enrich it with EPSS and KEV data, and produce a prioritized remediation queue with SLAs.

Quick Start

Score and prioritize the vulnerabilities in my latest scan report using CVSS v4.0, EPSS, and asset criticality, then assign remediation SLAs.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prioritize vulnerabilities with CVSS scoring?▼

Score each vulnerability using CVSS v4.0 base metrics, then enrich with threat intelligence like EPSS scores and CISA KEV status. Combine these with asset criticality and network exposure in a weighted matrix rather than relying on the base score alone.

What is the difference between CVSS v4.0 and v3.1?▼

CVSS v4.0 adds Attack Requirements (AT), expands User Interaction values, splits impact metrics into vulnerable and subsequent systems, and introduces Supplemental metrics like Safety and Automatable. It was released by FIRST in November 2023.

Should I use CVSS base score alone for vulnerability prioritization?▼

No. CVSS base score measures intrinsic severity, not organizational risk. Effective prioritization blends CVSS with EPSS exploit probability, CISA KEV listings, asset criticality from your CMDB, and network exposure data.

How do I read a CVSS v4.0 vector string?▼

A vector like CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H encodes each metric as an abbreviation-value pair. AV:N means network attack vector, PR:N means no privileges required, and VC:H means high confidentiality impact.

What are the limitations of CVSS for risk assessment?▼

CVSS measures severity, not risk, and ignores your specific deployment context unless environmental metrics are set. Scanner-provided scores can also be wrong, so verify the vector string matches the actual vulnerability before trusting the number.
