CVE-2021-26583Network attack vector

Unauthenticated remote code execution

Published May 10, 2021 · Updated Aug 3, 2024

Remote code execution in HPE iLO Amplifier Pack before 1.90 allows remote attackers to execute arbitrary code without authentication. HPE identifies use of the Bootstrap framework but has not published the affected endpoint or the wrong operation performed on untrusted input. Network access to the appliance is sufficient, and successful exploitation permits complete compromise of its data, configuration, and availability.
