How Secuno handles this

Secuno correlates vulnerabilities like CVE-2014-4113 against the real software inventory on every managed device, every day.

Because it is on the CISA KEV list, Secuno flags any affected asset as top-priority automatically. If an affected version is present anywhere across your portfolio, it surfaces automatically with a prioritised remediation path.
