CVE-2024-54085Known exploitationPublic exploitNetwork attack vector

Unauthenticated BMC control via spoofed HTTP header

Published Mar 11, 2025 · Updated Feb 26, 2026

Authentication bypass in AMI MegaRAC SP-X 12.0 through 12.6 and 13.0 through 13.4 allows remote attackers to administer BMCs via Redfish. The check_host_interface_connection function extracts text before the first colon in an attacker-controlled X-Server-Addr or Host header and trusts a match to a host-interface address in Redis. The Redfish Host Interface must be enabled with AuthNone; successful access permits administrator account creation and full remote BMC control.
