Cryptographic compromise via hard-coded certificate key
Published Jul 5, 2023 · Updated Nov 21, 2024
Hard-coded key use in American Megatrends International MegaRAC SP-X before 12.3 allows attackers to read or alter BMC data. The BMC uses a fixed cryptographic key associated with a hard-coded certificate, but AMI has not disclosed the certificate's role or trigger. Exploitation requires adjacent-network access, user interaction, and high-complexity conditions; success can also interrupt BMC service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
