A local Denial of Service (DoS) and local arbitrary code execution vulnerability that could potentially lead to a loss of confidentiality, integrity, and availability were discovered in HPE Integrated Lights-Out 5 (iLO 5) in Version: 2.71. Hewlett Packard Enterprise has provided updated firmware for HPE Integrated Lights-Out 5 (iLO 5) that addresses these security vulnerabilities.

Security readout for executives and security teams

Plain-English summary

CVE-2022-28637 affects HPE Integrated Lights-Out 5 firmware. A user with local, low-privileged access could trigger denial of service or potentially execute arbitrary code, risking confidentiality, integrity, and availability. HPE says updated iLO 5 firmware addresses the issue.

Executive priority

Treat this as a high-priority firmware remediation item for HPE server fleets. It is not documented as actively exploited in the provided sources, but the potential impact is full confidentiality, integrity, and availability loss after local low-privileged access.

Technical view

The CVSS 3.1 vector is AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H with score 7.8. Sources identify HPE iLO 5 version 2.71 and versions prior to 2.72 as affected. The vulnerability is local, requires low privileges, and needs no user interaction.

Likely exposure

Exposure is most likely in environments running HPE Integrated Lights-Out 5 firmware prior to 2.72, particularly version 2.71. Risk depends on whether untrusted or compromised users can obtain local low-privileged access to affected systems.

Exploitation context

The provided sources do not state active exploitation, and the CVE is not marked KEV. The weakness is still serious because local code execution against management firmware can create high-impact confidentiality, integrity, and availability risk.

Researcher notes

Evidence is limited to public CVE data and HPE’s advisory reference. No CWE is provided in the bundle. Analysis should avoid assuming remote exploitability, unauthenticated access, or confirmed exploitation because the CVSS vector and description only support local, low-privileged exploitation.

Mitigation direction

  • Inventory HPE iLO 5 assets and record current firmware versions.
  • Upgrade affected iLO 5 firmware to HPE’s fixed release, 2.72 or later.
  • Review HPE advisory guidance before scheduling firmware updates.
  • Limit local low-privileged access to trusted users where feasible.
  • Prioritize systems supporting critical workloads or sensitive environments.

Validation and detection

  • Confirm each iLO 5 device firmware version is 2.72 or later.
  • Check asset inventory for any iLO 5 firmware prior to 2.72.
  • Verify change records show HPE firmware update completion.
  • Confirm vulnerability scanners no longer flag CVE-2022-28637.
  • Track exceptions for systems awaiting vendor-approved maintenance windows.
