Impact
Successful exploitation of these vulnerabilities could lead to the use of NTP daemons in distributed <span style="color: #454545;">denial of service (DDoS)</span> attacks. NOTE: Both Clustered Data ONTAP and Clustered Data ONTAP are affected only by CVE-2016-4954 which requires that the attacker know the addresses of more than half of the configured sources and only affects ntpd acting as a client. Neither product has plans to address that vulnerability.
Affected products
- Clustered Data ONTAP
- Data ONTAP operating in 7-Mode
- OnCommand Balance
- OnCommand Performance Manager (Unified Manager Performance Pkg)
- OnCommand Unified Manager for Clustered Data ONTAP

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).
- Harden in parallel: security hardening baseline and ransomware protection on ONTAP.
