CVE-2026-25201Network attack vector

Pre-auth code execution via unrestricted file upload

Published Feb 2, 2026 · Updated Feb 2, 2026

Unrestricted file upload in Samsung Electronics MagicINFO 9 Server before 21.1090.1 allows remote attackers to execute arbitrary code. MagicINFO accepts attacker-supplied files without adequately verifying dangerous file types, allowing uploaded content to reach a code-execution path; Samsung has not disclosed the affected endpoints or functions. Exploitation requires no account but requires user interaction under Samsung's assessment, and successful execution grants the server process's privileges.
