Security readout for executives and security teams
Plain-English summary
CVE-2022-28639 affects HPE Integrated Lights-Out 5 firmware before 2.72. An unauthenticated attacker with adjacent network access could potentially crash the management controller or execute code, threatening server management confidentiality, integrity, and availability.
Executive priority
High priority for infrastructure teams. iLO controls server management functions, so compromise or disruption can affect recovery, operations, and platform trust even when host operating systems are patched.
Technical view
The CVSS 3.1 vector is AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, scored 8.8. Sources describe potential adjacent denial of service and arbitrary code execution in HPE iLO 5 version 2.71 and earlier, associated with CWE-400.
Likely exposure
Organizations using HPE servers with iLO 5 firmware prior to 2.72 are the exposed population. Risk is highest where iLO management interfaces are reachable from shared, poorly segmented, or broadly accessible adjacent networks.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not marked as CISA KEV. Treat exploitation status as unconfirmed, while prioritizing remediation because the vulnerability is unauthenticated and has high confidentiality, integrity, and availability impact.
Researcher notes
Evidence is limited to the CVE record and HPE advisory reference. The CVSS adjacent-network vector is important for scoping, but the potential code execution impact warrants treating reachable management networks as sensitive.
Mitigation direction
- Upgrade HPE iLO 5 firmware to version 2.72 or later.
- Use HPE’s advisory to obtain current firmware and installation guidance.
- Prioritize iLO 5 version 2.71 and earlier in remediation queues.
- Track remediation completion across all HPE server management controllers.
Validation and detection
- Inventory HPE iLO 5 devices and record firmware versions.
- Flag iLO 5 firmware prior to 2.72 as affected.
- Confirm whether iLO interfaces are reachable from adjacent or shared networks.
- Recheck HPE advisory for any newer vendor guidance.
