CVE-2022-50591Network attack vector

Unauthenticated password disclosure via NetworkServlet SQL injection

Published Nov 6, 2025 · Updated Nov 15, 2025

SQL injection in Advantech iView before 5.7.04 build 6425 allows remote attackers to disclose user data and cleartext passwords. NetworkServlet accepts the unauthenticated ztp_config_id parameter as SQL input without neutralizing SQL syntax. No credentials or user interaction are required; the documented consequence is database disclosure rather than code execution or service interruption.
