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 local arbitrary code execution and a local denial of service (DoS) vulnerability within an isolated process were discovered in HPE Integrated Lights-Out 5 (iLO 5) firmware version(s): Prior to 2.71. An unprivileged user could locally exploit this vulnerability to potentially execute arbitrary code in an isolated process resulting in a complete loss of confidentiality, integrity, and availability within that process. In addition, an unprivileged user could exploit a denial of service (DoS) vulnerability in an isolated process resulting in a complete loss of availability within that process. A successful attack depends on conditions beyond the attackers control. HPE has provided a firmware update to resolve this vulnerability in HPE Integrated Lights-Out 5 (iLO 5).

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 vulnerability in HPE iLO 5 firmware prior to version 2.71 allows an unprivileged attacker to potentially execute arbitrary code within an isolated process, along with a local DoS vector against that same isolated process. The isolated nature of the compromised process limits the scope of impact to that process context rather than achieving full system compromise.

MitigationApply HPE firmware version 2.71 or later to all affected iLO 5 devices to resolve this vulnerability. As this is a local attack, ensure physical access controls and management network segmentation are in place as defense-in-depth.

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. Check iLO 5 firmware version via web interface
    Log in to the iLO web interface using a browser (https://<ilo-ip>), then navigate to the Dashboard or Information > General page to view the Firmware Version field.
    Affected if The displayed Firmware Version is less than 2.71 (for example, 2.60, 2.65, 2.70).
  2. Check iLO 5 firmware version via iLO REST API or ilorest
    Run 'ilorest login <ilo-ip> -u <username> -p <password>' followed by 'ilorest select Manager' and 'ilorest info' to retrieve the firmware version from the Manager resource.
    Affected if The FirmwareVersion or Manager. firmwareVersion property returned is less than 2.71.
  3. Check iLO 5 firmware version via hponcfg
    Run the hponcfg utility on the host system (hponcfg -g) to retrieve current iLO firmware information, or use hponcfg -w to write the current configuration which includes the iLO firmware version.
    Affected if The firmware version reported by hponcfg is below 2.71.
  4. Check iLO 5 firmware version via hpasmcli
    Run hpasmcli from the host OS and execute 'show sel' or 'show server' to display system information including the iLO firmware version.
    Affected if The iLO firmware version shown is less than 2.71.

You are affected if your HPE iLO 5 firmware version is below 2.71; versions 2.71 and later are not vulnerable.

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 · scoped
Upgrade available Upgrade to 2.71 or later
Fixed in 2.71
Interim mitigation

Apply HPE firmware version 2.71 or later to all affected iLO 5 devices to resolve this vulnerability. As this is a local attack, ensure physical access controls and management network segmentation are in place as defense-in-depth.

Recommended fix High confidence

iLO 5 firmware version 2.71

  1. Obtain the iLO 5 firmware version 2.71 or later from the HPE support website (support.hpe.com)
  2. Review the HPE iLO 5 firmware upgrade documentation for your specific HPE server model
  3. Follow the recommended firmware update procedure for your server, typically using the HPE Smart Update Manager (SUM) or iLO Integrated Remote Console
  4. Verify the firmware upgrade was successful by checking the iLO firmware version in the iLO web interface or via command line
Caveat Firmware upgrades carry inherent risk and should be performed according to HPE's documented procedures; ensure adequate power backup and follow server-specific upgrade instructions
