  # Version: 5.1 < 5.0
  # Tested on: Windows 10 
  # CVE : N/A
  
  #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.'''
