Product web page: https://www.sielco.org
Affected version: 2.06 (RTX19)
                  2.05 (RTX19)
                  2.00 (EXC19)

Summary: Sielco develops and produces radio links for all
transmission and reception needs, thanks to innovative units
and excellent performances, accompanied by a high reliability
and low consumption.

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.

Tested on: lwIP/2.1.1
           Web/2.9.3
