You can do it "as usual" in PHP. I just did it a few days ago like this:

$path = "/img/avatars/";
$dir = getcwd().$path;
$avatarFile = "$dir$id.png";

if (isset($this->data['User']['avatar']) && $this->data['User']['avatar']['error'] == 0) {
                $avatar = $this->data['User']['avatar'];
                if (!is_uploaded_file($avatar['tmp_name'])) $this->Utils->panic($avatar);

                if (in_array($avatar['type'], array('image/jpeg','image/pjpeg','image/png'))) {

                    // load image
                    list($width,  $height) = getimagesize($avatar['tmp_name']);
                    $width = $height = min($width, $height);

                    if (in_array($avatar['type'], array('image/jpeg','image/pjpeg')))
                        $source = imagecreatefromjpeg($avatar['tmp_name']);
                    else
                        $source = imagecreatefrompng($avatar['tmp_name']);

                    // resize
                    $thumb = imagecreatetruecolor(128, 128);
                    imagecopyresized($thumb,  $source,  0,  0,  0,  0,  128,  128,  $width,  $height);

                    // save resized & unlink upload
                    imagepng($thumb, $avatarFile);

                    $success &= true;
                } else {
                    $this->User->invalidate('avatar', __("Only JPG or PNG accepted.",true));
                    $success &= false;
                }

                unlink($avatar['tmp_name']); // Delete upload in any case
            }

It's even going to resize it for you always to 128x128, you can skip that and just rename the uploaded image to the target dir. Google will also help you out, there is nothing Cake specific for file uploads.

The uploading form:

echo $form->create('User', array(
    'enctype' => 'multipart/form-data',
    'type' => 'post',
));
echo $form->input('avatar', array('type' => 'file', 'label' => __('Avatar:',true)));
