CVE-2021-29220Network attack vector

Authenticated code execution via undisclosed buffer overflows

Published Feb 24, 2022 · Updated Aug 3, 2024

Buffer overflows in HPE iLO Amplifier Pack before 2.12 allow remote authenticated users to execute code with appliance privileges. HPE identifies multiple remote buffer overflows but does not disclose the affected component, input, or copy operation that exceeds its destination buffer. Exploitation requires a highly privileged account and can expose or alter managed data and interrupt appliance service through arbitrary code execution.
