CVE-2022-2143Public exploitNetwork attack vector

Unauthenticated code execution via NetworkServlet command injection

Published Jul 22, 2022 · Updated Apr 16, 2025

Command injection in Advantech iView before 5.7.04.6469 allows remote attackers to execute arbitrary code through the NetworkServlet endpoint. NetworkServlet passes the backupDatabase backup_filename and runProViewUpgrade fwfilename values to system calls without adequate validation. No authentication or user interaction is required, and successful exploitation runs code as NT AUTHORITY\SYSTEM.
