CVE-2023-34343Network attack vector

Authenticated shell command execution via SPX REST API

Published Jun 12, 2023 · Updated Jan 3, 2025

OS command injection in AMI MegaRAC SP-X branch 12 before 12.7 and branch 13 before 13.5 allows remote authenticated users to run shell commands. The SPX REST API incorporates attacker-controlled request data into an operating-system command without neutralizing shell metacharacters; AMI has not named the endpoint. Administrative BMC privileges are required; injected commands can read or alter BMC data, interrupt service, or take control of the management controller.
