Overall CVSS score (tenable)

Ronald (Access42)
3 2

Tenable uses the CVSS scoring method for detected vulnerabilities. To have an overall CVSS, use the following query:

sourcetype="tenable:sc:vuln" ip=* |stats mean(baseScore) as base | eval base = round(base,2)

1	sourcetype="tenable:sc:vuln" ip=* \|stats mean(baseScore) as base \| eval base = round(base,2)
