CVE-2016-1894 Netapp CVE debrief

CVE-2016-1894 is an authentication bypass issue in NetApp OnCommand Workflow Automation. According to the CVE/NVD record and NetApp references, affected releases are versions before 3.1P2. Because the flaw can let a remote attacker bypass authentication, it should be treated as a high-priority exposure on any internet-reachable or broadly trusted Workflow Automation deployment.

Who should care

Administrators and security teams responsible for NetApp OnCommand Workflow Automation, especially environments that expose the service to internal users, automation tooling, or any network segment with broad access.

Technical summary

The vulnerability is described as a remote authentication bypass via unspecified vectors in NetApp OnCommand Workflow Automation before 3.1P2. NVD maps the issue to CWE-284 (Improper Access Control) and assigns a CVSS v3.0 vector of AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H with a score of 8.1. The published sources do not provide exploit mechanics, so only the vendor/NVD remediation guidance should be used for validation and response.

Defensive priority

High. Authentication bypass in a workflow automation platform can expose privileged operations and sensitive data, so patching or upgrade verification should be prioritized ahead of routine maintenance.

Recommended defensive actions

  • Confirm whether any OnCommand Workflow Automation instances are running versions earlier than 3.1P2.
  • Upgrade affected systems to a fixed release using NetApp's advisory and KB guidance.
  • Review access logs and authentication events around the service for unexpected or unauthenticated access attempts.
  • Restrict network exposure of Workflow Automation to trusted management networks until remediation is complete.
  • Verify that downstream automation accounts and credentials used by the platform have not been misused.
  • Document remediation status and keep the vendor advisory and NVD record as the authoritative references for validation.

Evidence notes

Source-backed facts used here come from the NVD record and the linked NetApp materials. The CVE description states that NetApp OnCommand Workflow Automation before 3.1P2 allows remote attackers to bypass authentication via unspecified vectors. NVD classifies the weakness as CWE-284 and gives CVSS v3.0 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H (8.1). No exploit method or additional affected-product details were inferred beyond the supplied record and official references.
