CVE-2023-28392Network attack vector

Administrator command execution via unneutralized WEB input

Published May 23, 2023 · Updated Jan 17, 2025

OS command injection in Inaba Wi-Fi AP UNIT firmware allows remote authenticated users with administrative privileges to execute arbitrary commands. The WEB configuration interface accepts an undisclosed browser-supplied value without adequately neutralizing command syntax before forming an OS command. Administrative access and connectivity to that interface are required, and successful exploitation grants command execution on the appliance.
