CVE-2025-54449Network attack vector

Unauthenticated SYSTEM code execution via arbitrary file upload

Published Jul 23, 2025 · Updated Feb 26, 2026

Unrestricted file upload in Samsung Electronics MagicINFO 9 Server before 21.1080.0 allows remote attackers to execute code as SYSTEM. The fillLftOrLfdInfo method fails to validate user-supplied upload data and accepts arbitrary files that the server can execute. Authentication is not required, and successful exploitation grants SYSTEM-level control of the server.
