CVE-2016-6495 Netapp CVE debrief

Who should care

Administrators and security teams responsible for NetApp Data ONTAP 7-Mode systems, especially environments that still expose HTTP access on volumes or have legacy storage management services in production.

Technical summary

NVD classifies this issue as CVSS 3.0: AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N with CWE-200. The vulnerable condition is limited to Data ONTAP before 8.2.4P5 in 7-Mode. The issue allows remote disclosure of information about volumes configured for HTTP access, making it a confidentiality exposure rather than an integrity or availability flaw.

Defensive priority

Moderate. Prioritize remediation for any 7-Mode deployment that is still in service, especially if HTTP access is enabled or reachable from untrusted networks. The issue is not listed as KEV, but it is a direct information disclosure vector with no authentication requirement.

Recommended defensive actions

• Upgrade NetApp Data ONTAP to 8.2.4P5 or later, following the vendor advisory.
• Review whether HTTP access is actually needed for any volumes, and disable or restrict it where possible.
• Limit network exposure to storage and management interfaces so only trusted administrative networks can reach them.
• Inventory remaining Data ONTAP 7-Mode systems and include them in legacy-technology risk tracking.
• Validate patch status against the NetApp advisory and confirm affected systems are not running versions before 8.2.4P5.
