CVE-2020-7139
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 remote access security vulnerabilities have been identified with HPE Nimble Storage systems that could be exploited by an attacker to access and modify sensitive information on the system. The following NimbleOS versions, and all subsequent releases, contain a software fix for this vulnerability: 3.9.3.0 4.5.6.0 5.0.9.0 5.1.4.100
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 confidenceRemote access vulnerability in HPE Nimble Storage systems allowing unauthorized access and modification of sensitive data. The specific vulnerability mechanism is not detailed in available materials, but affects NimbleOS versions prior to the fixed releases.

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.
-
Check NimbleOS version via CLISSH to the Nimble array and run the command `show version` or `show system` to retrieve the installed OS version.Affected if The reported version falls within any of these ranges: 3.1.0.0-3.9.3.0, 4.1.0.0-4.5.6.0, 5.0.1.0-5.0.9.0, or 5.1.0.0-5.1.4.100.
-
Check NimbleOS version via web management interfaceLog in to the Nimble web UI (typically https://<array-ip>/) and navigate to the About or System Information page to view the OS version.Affected if The displayed version matches any of the affected ranges listed above.
-
Verify remote management service exposureFrom an external host, attempt to reach the Nimble management ports (default HTTPS port 443) to confirm the remote management interface is accessible on the network.Affected if The remote management interface is exposed and the NimbleOS version is within the affected ranges.
-
Check for unauthorized admin accountsLog in to the Nimble CLI or web UI as an administrator and review the list of local user accounts for any unexpected or unauthorized admin-level accounts.Affected if Unknown or unauthorized accounts exist and the NimbleOS version is within the affected version ranges.
The environment is affected if the installed NimbleOS version falls within any of the four vulnerable version ranges and remote management services are accessible.
