Tenable provides plugins to detect the presence of these vulnerabilities. For example, Nessus can scan for "PHP 5.6.x < 5.6.40 Multiple vulnerabilities." The detailed report from such a scan will list each detected CVE, confirm the version, and provide remediation steps. A clean scan result can serve as a verification that the software version has been updated.
