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 · unedited
A potential security vulnerability has been identified in HPE Superdome Flex and Superdome Flex 280 servers. The vulnerability could be locally exploited to allow disclosure of information. HPE has made the following software to resolve the vulnerability in HPE Superdome Flex Servers v3.65.8 and Superdome Flex 280 Servers v1.45.8.

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 confidence

A local information disclosure vulnerability in HPE Superdome Flex and Superdome Flex 280 servers. The vulnerability allows a local attacker to potentially access sensitive information. This is a local-only exploit requiring some level of access to the system.

MitigationApply HPE vendor software updates: upgrade HPE Superdome Flex Servers to v3.65.8 and Superdome Flex 280 Servers to v1.45.8 or later.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify server model
    Check if the system is an HPE Superdome Flex or Superdome Flex 280 server. This can be done via iLO web interface, iLO REST API, or physical system label.
    Affected if The system is not a Superdome Flex or Superdome Flex 280 server (not affected)
  2. Access iLO management interface
    Log into the HPE iLO web interface or use iLO REST API (https://<ilo-ip>/redfish/v1/) to access server management information. The iLO credential is typically required.
    Affected if Unable to access iLO interface - local verification may require physical access or existing admin credentials
  3. Retrieve current firmware version
    Navigate to the iLO web interface: Overview > Server Information > Firmware Version. Alternatively, use Redfish: GET /redfish/v1/Managers/Self or /redfish/v1/Systems/1. Look for the System ROM or iLO firmware version field.
    Affected if Firmware version cannot be retrieved from the management interface
  4. Compare firmware version against affected ranges
    For Superdome Flex 280: compare your System ROM version to 1.45.8 (affected if < 1.45.8). For Superdome Flex: compare to 3.65.8 (affected if < 3.65.8). Note the exact version string from the iLO or Redfish output.
    Affected if Installed firmware version is below 1.45.8 for Superdome Flex 280, or below 3.65.8 for Superdome Flex
  5. Verify local access exposure
    Determine if untrusted local users or processes have access to the system. Check for shared local accounts, console access, or virtual machine escape paths. Review system logs for unauthorized local access attempts.
    Affected if Untrusted local users can access the server and the firmware version is in the affected range

A system is affected if it is an HPE Superdome Flex (firmware < 3.65.8) or Superdome Flex 280 (firmware < 1.45.8) server, and an attacker can gain local access to the system.

dbcve · scoped
Upgrade available Upgrade to 1.45.8 / 3.65.8 or later
Fixed in 1.45.83.65.8
Interim mitigation

Apply HPE vendor software updates: upgrade HPE Superdome Flex Servers to v3.65.8 and Superdome Flex 280 Servers to v1.45.8 or later.

Recommended fix Moderate confidence

Superdome Flex Server: upgrade to firmware v3.65.8; Superdome Flex 280 Server: upgrade to firmware v1.45.8

  1. Obtain the fixed firmware version from HPE support: v3.65.8 for Superdome Flex Servers or v1.45.8 for Superdome Flex 280 Servers
  2. Download the firmware update package from support.hpe.com
  3. Review HPE firmware update documentation for your specific server model
  4. Apply the firmware update using the HPE iLO management interface or HPE SUM (Smart Update Manager)
  5. Verify the firmware version has been successfully updated after reboot
Caveat Firmware updates may require server downtime and should be planned during maintenance windows
