Sielco PolyEco Digital FM Transmitter 2.0.6 Radio Data System POST Manipulation


Vendor: Sielco S.r.l
Product web page: https://www.sielco.org
Affected version: PolyEco1000 CPU:2.0.6 FPGA:10.19
                  PolyEco1000 CPU:1.9.4 FPGA:10.19
                  PolyEco1000 CPU:1.9.3 FPGA:10.19
                  PolyEco500 CPU:1.7.0 FPGA:10.16
                  PolyEco300 CPU:2.0.2 FPGA:10.19
                  PolyEco300 CPU:2.0.0 FPGA:10.19

Summary: PolyEco is the innovative family of high-end digital
FM transmitters of Sielco. They are especially suited as high
performance power system exciters or compact low-mid power
transmitters. The same cabinet may in fact be fitted with 50,
100, 300, 500, 1000W power stage (PolyEco50, 100, 300, 500,
1000).

All features can be controlled via the large touch-screen display
4.3" or remotely. Many advanced features are inside by default
in the basic version such as: stereo and RDS encoder, audio
change-over, remote-control via LAN and SNMP, "FFT" spectral
analysis of the audio sources, SFN synchronization and much more.

Desc: Improper access control occurs when the application provides
direct access to objects based on user-supplied input. As a result
of this vulnerability attackers can bypass authorization and access
resources behind protected pages. The application interface allows
users to perform certain actions via HTTP requests without performing
any validity checks to verify the requests. This can be exploited
to perform certain actions and manipulate the RDS text display.

Tested on: lwIP/2.1.1 (http://savannah.nongnu.org/projects/lwip)
