CVE-2023-30911Network attack vector

Service interruption via undisclosed iLOrest flaw

Published Oct 18, 2023 · Updated Sep 13, 2024

Denial of service in Hewlett Packard Enterprise Integrated Lights-Out 5 before 2.98 and 6 before 1.53 allows attackers to interrupt iLO. HPE identifies iLOrest as the affected interface but has not published the request, operation, or internal fault that triggers the failure. HPE's vector requires high privileges, while NVD's assessment treats the path as unauthenticated; the documented consequence is loss of availability.
