CVE-2016-8754
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 · uneditedHuawei OceanStor 5600 V3 V300R003C00 has a hardcoded SSH key vulnerability; the hardcoded keys are used to encrypt communication data and authenticate different nodes of the devices. An attacker may obtain the hardcoded keys and log in to such a device through SSH.
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 · high confidenceThe Huawei OceanStor 5600 V3 V300R003C00 storage system contains hardcoded SSH keys embedded in the firmware. These keys are used both for encrypting inter-node communication within the storage cluster and for SSH authentication, allowing any attacker who obtains these keys to gain unauthorized administrative access to the device via SSH.

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.
-
Identify the storage device modelAccess the storage system management interface or use CLI commands to display the device model information. Look for 'OceanStor 5600 V3' in the system inventory or product details.Affected if The device model is NOT OceanStor 5600 V3 (different models are not affected by this specific CVE)
-
Check the firmware versionUse the storage system CLI or management interface to display the current firmware version. Common commands include 'show version' or accessing the system information panel.Affected if The firmware version is NOT v300r003c00 (other versions may have different key management and are not in scope for this CVE)
-
Verify SSH service is enabledCheck the storage system configuration for SSH service status. This may be accessible through the system security settings, service management panel, or by attempting an SSH connection to the device management IP.Affected if SSH service is disabled and no inter-node SSH communication is configured (the hardcoded keys cannot be exploited if SSH is not active)
-
Inspect for hardcoded SSH keys in firmwareAccess the device firmware or system backup files to examine the SSH key configuration. On the storage controller, navigate to the SSH daemon configuration or examine the firmware image for embedded key files.Affected if Hardcoded SSH keys matching the Huawei OceanStor default key set are present in the system (this confirms the specific vulnerability is exploitable)
The environment is affected only if the device is an OceanStor 5600 V3 running firmware v300R003C00 with SSH service enabled and containing the hardcoded SSH keys from the firmware.

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 dataReplace all hardcoded SSH keys with dynamically generated, unique keys per device; rotate keys across all affected nodes in the cluster and verify inter-node communication functions correctly with the new credentials.
