Los registradores de datos Campbell Scientific CR6, CR300, CR800, CR1000 y CR3000 pueden permitir a un atacante descargar archivos de configuración, que pueden contener información confidencial sobre la red interna. Por defecto de fábrica, los registros de datos mencionados tienen HTTP y PakBus habilitados. Los dispositivos, con la configuración predeterminada, permiten esta situación a través del puerto PakBus. La explotación de esta vulnerabilidad puede permitir a un atacante descargar, modificar y cargar nuevos archivos de configuración.
