You can do this via observer in custom module:

<?xml version="1.0"?>
    <!-- some config here -->
    <!-- some config here-->

And Model/Observer.php

class My_Module_Model_Observer
    public function catalogProductPrepareSave($observer)
         * @var $product Mage_Catalog_Model_Product
        $product = $observer->getEvent()->getProduct();
            $product->setSomeAttribute("Some default value here");
