Who should care

NetApp Clustered Data ONTAP administrators, storage teams managing SMB/CIFS services, and security teams responsible for protecting share metadata and access patterns in enterprise NAS environments.

Technical summary

The vulnerability is classified as CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). NVD describes it as a network-reachable issue with no privileges or user interaction required (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), meaning the primary impact is confidentiality. The NVD record references affected Clustered Data ONTAP versions and the vendor advisory indicates remediation at 8.3.2P7.

Defensive priority

High. The issue is remotely reachable, requires no authentication, and can expose SMB share information, which may aid reconnaissance or reveal sensitive storage topology and access details.

Recommended defensive actions

  • Review NetApp advisory NTAP-20161028-0001 and confirm whether any Clustered Data ONTAP systems are in the affected range.
  • Upgrade affected NetApp Clustered Data ONTAP systems to 8.3.2P7 or later, as indicated by the vulnerability description.
  • Audit SMB share exposure and related access controls on NetApp appliances to reduce unnecessary information disclosure.
  • Verify asset inventories for any Clustered Data ONTAP deployments that may be running versions mapped by NVD as vulnerable.
  • Recheck the NVD and vendor advisory for any updated remediation guidance or version scope clarifications.

Evidence notes

The CVE record was published on 2017-02-07 and later modified on 2026-05-13; that later date reflects record maintenance, not the original issue date. The supplied NVD metadata describes the flaw as remote SMB share information disclosure, gives CVSS vector CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, and lists CWE-200. The vendor reference provided in the corpus is NetApp KB NTAP-20161028-0001. The supplied corpus also contains an NVD CPE mapping to clustered_data_ontap up to 8.3.2, while the narrative description says before 8.3.2P7; both are retained here as source-backed context without resolving the discrepancy beyond what the corpus states.
