  • Monitor HTTP requests to the /NetworkServlet endpoint for the presence of the `backup_file` parameter containing mysqldump flags such as `-r` or `-w`, which are indicative of exploitation attempts.
  • Alert on unauthenticated POST/GET requests to the NetworkServlet endpoint on Advantech iView instances, especially those originating from external/untrusted sources.
  • Detect processes spawned as NT AUTHORITY\SYSTEM by the Advantech iView service, particularly child processes of mysqldump or web server processes, which may indicate successful RCE.
  • ·The existing sanitization only checks for SQL injection and directory traversal patterns, meaning standard WAF rules targeting those patterns alone will NOT block this exploit. Detection must also cover mysqldump flag injection (e.g., `-r`, `-w`) in the `backup_file` parameter.
  • ·This vulnerability affects TWO separate instances of command injection in the product, so patching or detection should account for both attack surfaces.
