CVE-2025-54441Network attack vector

SYSTEM code execution via unrestricted font 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 authenticated users to execute code as SYSTEM. The getFontFileFromMagicInfoServer method accepts user-supplied files without validating whether their type is safe, permitting arbitrary file upload. Exploitation reaches an authenticated network request, although the existing authentication mechanism can be bypassed, and successful execution inherits SYSTEM privileges.
