Validating Vulnerability Analysis with Statistical Analysis of Metadata
summary
Claims that metadata can predict analyst impact decisions get tested on a 7,415-vulnerability dataset using CVSS, CWE and component fields. CVSS vectors get encoded with mixed-radix CVSS indexing, CWE nodes get ordered via DFS on the CWE graph, and clustering produces six bands (e.g., “DOSville”, “piville”, “data manipulation”) that map to specific CWEs. A nearest-neighbor distance helps flag anomalies (example: CVE‑2024‑4896) and suggests relevant past cases to speed validation.
