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 an user with Administrator access to escalate their privilege. The vulnerability is resolved in the latest firmware update. HPE Superdome Flex Server Version 3.50.58 or later, HPE Superdome Flex 280 Server Version 1.20.204 or later.

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

This is a local privilege escalation vulnerability in HPE Superdome Flex server firmware. A user with Administrator-level access can exploit the flaw to gain elevated privileges beyond their intended scope. The vulnerability exists in the firmware privilege handling mechanism and is exploitable only with local access and existing administrative credentials.

MitigationApply the latest firmware update: Version 3.50.58 or later for HPE Superdome Flex Server, and Version 1.20.204 or later for HPE Superdome Flex 280 Server. Schedule a planned maintenance window to apply the firmware update following HPE's documented firmware update procedures.

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 the HPE Superdome Flex model
    Locate the server model label or check system inventory documentation to confirm whether you have HPE Superdome Flex Server or HPE Superdome Flex 280
    Affected if The model is either Superdome Flex or Superdome Flex 280 (both are affected)
  2. Check the installed firmware version
    Access the server's iLO or management interface to view the current firmware version, or use the system's firmware version display command
    Affected if The firmware version is below 3.50.58 for Superdome Flex, or below 1.20.204 for Superdome Flex 280
  3. Verify local access scope
    Confirm whether standard user accounts or untrusted personnel have physical or console-level access to the server
    Affected if Local access is available to users beyond the trusted administrator group
  4. Review administrative account configuration
    Check the list of accounts with Administrator-level privileges on the system
    Affected if Multiple administrative accounts exist, especially if any are shared or have non-personal accountability

Your environment is affected if the installed firmware version is below 3.50.58 (Superdome Flex) or below 1.20.204 (Superdome Flex 280) AND local access with existing administrative credentials is present in your environment.

Interim mitigation

Apply the latest firmware update: Version 3.50.58 or later for HPE Superdome Flex Server, and Version 1.20.204 or later for HPE Superdome Flex 280 Server. Schedule a planned maintenance window to apply the firmware update following HPE's documented firmware update procedures.

Recommended fix High confidence

Superdome Flex Server: Version 3.50.58 or later; Superdome Flex 280 Server: Version 1.20.204 or later

  1. Identify the current firmware version of the HPE Superdome Flex or Superdome Flex 280 Server using the iLO management interface or HPE OneView
  2. Navigate to the HPE Support Center at support.hpe.com and search for your specific server model
  3. Locate and download the latest firmware version: 3.50.58 or later for Superdome Flex, or 1.20.204 or later for Superdome Flex 280
  4. Review the HPE firmware update guide and ensure proper backup of configuration data
  5. Apply the firmware update through the iLO Integrated Remote Console or HPE OneView, following the documented upgrade procedure
  6. Verify the firmware version after update to confirm the patch was successfully applied
Caveat Firmware updates may require system downtime; follow HPE's recommended update procedure to avoid boot or configuration issues
