CVE-2022-37907Network attack vector

System hang via undisclosed bootloader flaw

Published Nov 3, 2022 · Updated May 2, 2025

Denial of service in the ArubaOS bootloader on 7xxx series controllers allows remote authenticated users to hang the system. HPE has not published the bootloader operation or crafted input that triggers the condition, so the mechanism remains undisclosed. Exploitation requires high privileges and high complexity, and recovery requires a physical power cycle of the affected controller.
