Sielco PolyEco Digital FM Transmitter 2.0.6 Default Credentials 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: The FM transmitter uses a weak set of default administrative credentials that can be easily guessed in remote password attacks and gain full control of the system.
