  Summary: The SIGNUM controller from Elber satellite equipment demodulates
  one or two DVB-S/ S2 signals up to 32APSK (single/multi-stream), achieving
  256 KS/s as minimum symbol rate. The TS demodulated signals can be aligned
  and configured in 1+1 seamless switching for redundancy. Redundancy can also
  be achieved with external ASI and TSoIP inputs. Signum supports MPEG-1 LI/II
  audio codec, providing analog and digital outputs; moreover, it’s possible
  to set a data PID to be decoded and passed to the internal RDS encoder,
  generating the dual MPX FM output.
  
  Desc: The device suffers from an unauthenticated device configuration and
  client-side hidden functionality disclosure.
