CVE-2023-31198Network attack vector

Administrator command execution via crafted requests

Published Jun 13, 2023 · Updated Jan 3, 2025

OS command injection in Inaba Denki Sangyo Wi-Fi AP UNIT firmware allows remote authenticated users to execute arbitrary OS commands. The vendor and JVN identify only a specially crafted request; neither publishes the affected handler, parameter, or shell invocation. Administrative access is required, and successful exploitation grants command execution with the appliance's operating-system privileges.
