CVE-2022-28631

Unauthenticated code execution and isolated-process denial of service

Published Aug 11, 2022 · Updated Aug 3, 2024

Code execution and denial of service in HPE Integrated Lights-Out 5 firmware before 2.71 allow attackers to compromise an isolated process. HPE has not disclosed the affected firmware component or the operation on untrusted input that causes either behavior. Network adjacency and no authentication are required; successful exploitation executes code or interrupts service only within the isolated process.
