Vuln file: cart.php

Vuln code:

---------

if ( $a == "add" )

{

$templatefile = "configureproductdomain";

....etc

}

if ( $a == "login" )

{

$templatefile = "login";

....etc

}

...

outputClientArea( $templatefile, $nowrapper );

# outputClientArea function will display

"./templates/orderforms/cart/{$templatefile}.tpl"

Details :

---------

if variable "$a" has a true value .. will set "$templatefile" value by

default

but when "$a" value didn't match the defaults values

you can control "$templatefile" and use it as ( File Disclosure )
