CVE-2016-1895
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNetApp Data ONTAP before 8.2.5 and 8.3.x before 8.3.2P12 allow remote authenticated users to cause a denial of service via vectors related to unsafe user input string handling.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNetApp Data ONTAP contains a denial of service vulnerability in versions prior to 8.2.5 and 8.3.x before 8.3.2P12. The issue stems from unsafe user input string handling that allows authenticated remote attackers to crash the system via specially crafted input.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine Data ONTAP versionRun the command 'version' or 'sysconfig -a' at the cluster shell prompt to retrieve the installed Data ONTAP version numberAffected if The displayed version is 8.2.4 or earlier, or is 8.3.x version earlier than 8.3.2P12 (for example, 8.3.1, 8.3.0)
-
Verify the exact 8.3.2 patch levelIf running 8.3.2, confirm the full patch version by running 'version -detail' or checking the system boot messages for the exact build string including the P12 designationAffected if The system shows version 8.3.2 without the P12 patch (such as 8.3.2P11 or earlier)
-
Confirm authentication is enabledCheck if remote authentication protocols (such as SNMP, HTTP/HTTPS management interfaces, or SSH) are accessible by testing connectivity to ports 22, 80, 443, or 161/162 from a remote locationAffected if The management interfaces are reachable from network segments accessible to untrusted users, allowing an authenticated attacker to send the specially crafted input
You are affected if your Data ONTAP version is 8.2.4 or earlier, or is any 8.3.x version prior to 8.3.2P12, and the management interfaces are network-accessible to authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Data ONTAP to version 8.2.5 or later, or 8.3.2P12 or later. If immediate patching is not feasible, consider network segmentation to limit exposure to authenticated users and monitor for unusual access patterns.
