Summary: Sielco designs and produces FM radio transmitters
for professional broadcasting. The in-house laboratory develops
standard and customised solutions to meet all needs. Whether
digital or analogue, each product is studied to ensure reliability,
resistance over time and a high standard of safety. Sielco
transmitters are distributed throughout the world and serve
many radios in Europe, South America, Africa, Oceania and China.

Desc: The Cookie session ID 'id' is of an insufficient length and
can be exploited by brute force, which may allow a remote attacker
to obtain a valid session, bypass authentication and manipulate
the transmitter.
