Unauthenticated arbitrary file upload leading to RCE in Samsung MagicInfo 9 Server
CVE-2026-25201 is an unauthenticated arbitrary file upload vulnerability in Samsung MagicInfo 9 (MagicInfo9) Server affecting versions prior to 21.1090.1. Due to insufficient validation of user authentication and uploaded file type, a remote attacker can upload arbitrary files (e.g., a malicious script/web shell) and achieve remote code execution on the MagicInfo 9 Server, which can subsequently lead to privilege escalation to administrative control.
