CVE-2025-54438Network attack vector

Unauthenticated web shell upload via path traversal

Published Jul 23, 2025 · Updated Feb 26, 2026

Path traversal in Samsung Electronics MagicINFO 9 Server before 21.1080.0 allows remote attackers to upload executable web shells. The downloadChangedFiles function uses a user-supplied path in file operations without adequately validating that it remains in the intended directory. No authentication or user interaction is required, and a successful request places attacker-controlled executable content on the web server.
