CVE-2019-11996
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 · uneditedPotential security vulnerabilities have been identified with HPE Nimble Storage systems in multi array group configurations. The vulnerabilities could be exploited by an attacker to gain elevated privileges on the array. The following NimbleOS versions, and all subsequent releases, contain a software fix for this vulnerability: 3.9.2.0, 4.5.5.0, 5.0.8.0 and 5.1.3.0.
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 confidenceHPE Nimble Storage systems in multi-array group configurations contain a privilege escalation vulnerability allowing attackers to gain elevated privileges on the array, likely through an authentication bypass or improper authorization check in the storage management interface.

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.
-
Confirm HPE Nimble Storage systemIdentify if the storage array is an HPE Nimble product through hardware labeling, management interface, or system documentationAffected if System is confirmed as HPE Nimble Storage array
-
Determine NimbleOS versionAccess the Nimble storage management interface or CLI and retrieve the installed NimbleOS version numberAffected if Version falls within any of these ranges: 3.1.0.0-3.9.1.0, 4.1.0.0-4.5.4.0, 5.0.1.0-5.0.7.0, or 5.1.0.0-5.1.2.0
-
Check multi-array group configurationVerify whether the Nimble array is part of a multi-array group or group leader setup through the storage management interfaceAffected if Array is configured as part of a multi-array group
-
Verify management interface accessibilityConfirm that the storage management interface (web GUI or API) is network-accessible, even if only from internal networksAffected if Management interface is exposed on the network
User is affected if the system is an HPE Nimble Storage array running a NimbleOS version within the affected ranges AND configured in a multi-array group setup.

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.
dbcve · scopedUpgrade NimbleOS to version 3.9.2.0, 4.5.5.0, 5.0.8.0, 5.1.3.0 or later releases to remediate the vulnerability.
Upgrade to NimbleOS 3.9.2.0 (for 3.x branch), 4.5.5.0 (for 4.x branch), 5.0.8.0 (for 5.0.x branch), or 5.1.3.0 (for 5.1.x branch) depending on current version
- Identify the current NimbleOS version by accessing the array controller GUI or using the 'nsversion' CLI command
- Determine the appropriate upgrade path based on current version: versions 3.1.0.0-3.9.1.0 upgrade to 3.9.2.0; versions 4.1.0.0-4.5.4.0 upgrade to 4.5.5.0; versions 5.0.1.0-5.0.7.0 upgrade to 5.0.8.0; versions 5.1.0.0-5.1.2.0 upgrade to 5.1.3.0
- Review HPE Nimble Storage upgrade documentation and ensure compatibility with any connected infrastructure
- Create a complete array configuration backup before initiating the upgrade
- Schedule a maintenance window as upgrades require brief array downtime
- Download the appropriate NimbleOS firmware bundle from support.hpe.com
- Upload the firmware bundle through the Nimble GUI (Arrays > Update) or CLI using 'nimmupg' command
- Monitor the upgrade progress and verify all controllers update successfully
