The /dbviewer/ web endpoint in METIS WIC devices is exposed without authentication. A remote attacker can access and export the internal telemetry SQLite database containing sensitive operational data. Additionally, the application is configured with debug mode enabled, causing malformed requests to return verbose Django tracebacks that disclose backend source code, local file paths, and system configuration.
