What the CVE records say

CVE-2020-13817 — ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service (daemon exit or system time change) by predicting transmit timestamps for use in spoofed packets. The victim must be relying on unauthenticated IPv4 time sources. There must be an off-path attacker who can query time from the victim's ntpd instance.

What to do

Check the affected products listed above against the official advisory's affected-versions table — that is where the exact ONTAP 9 release, ONTAP tool, or management product versions are named.
If affected and a fixed release exists, plan the upgrade — see the ONTAP upgrade runbook.
If exploitation is listed as "active", treat remediation as urgent and review exposure (management LIFs, ONTAP S3, SnapMirror endpoints).
