CVE-2024-5421Network attack vector

Authenticated command execution via unvalidated web input

Published Jun 4, 2024 · Updated Feb 13, 2025

OS command injection in SEH utnserver Pro, ProMAX, and INU-100 20.1.22 and earlier allows remote authenticated users to execute commands. The CNA says unvalidated web input is integrated into an operating-system command but does not identify the parameter, endpoint, or command-construction path. Authentication is required; the CNA describes command execution, while its linked disclosure instead demonstrates file and directory reads through a hidden web function.
