    ============ Vulnerability Overview: ============ 
    
    * OS Command Execution:
    
    	parameter: maxmtu
    
    The vulnerability is caused by missing input validation in the maxmtu parameter and can be exploited to inject and execute arbitrary shell commands. It is possible to use Netcat to fully compromise the device.
    
    http://Target-IP/cgi-bin/setConfigSettings?maxmtu=%26COMMAND%26&hddstandby=2&hddacoustics=160&timeroffsetstart=0&timeroffsetstop=0&audiochannelspriority=&showsatpos=on&trustedhosts=&epgcachepath=%2Fhdd&epgsqlpath=%2Fvar%2Flib%2Fsqlite
    
    It is possible to shorten the URL to the following:
    
    http://Target-IP/cgi-bin/setConfigSettings?maxmtu=%26COMMAND%26
    
    There is Netcat preinstalled on the device. It is a very small edition of netcat, so you have to play a bit with it but you will get it ;)
    
    * stored XSS:
    
    Box Control -> Configuration -> Webserver -> User, Password
    
    	parameter: AuthUser, AuthPassword
    
    Box Control -> Configuration -> Settings
    
    	parameter: audiochannelspriority
    
    Injecting scripts into the parameter xxx reveals that this parameter is not properly validated for malicious input.
    
    ============ Solution ============
