[Full-Disclosure] Centre 1.0 PHP injection, bypass authentication + possible SQL injection.

[Manip]

Summary: The Miller Group, Inc. [www.miller-group.net] announces the release 
of Centre, a free student information system for public and non-public 
schools. Centre is a web-based, open source, student management product with 
features that include scheduling, grade book, attendance, eligibility, 
transcripts, and more. And, of course, student and employee information 
screens are critical components of Centre.

Version: 1.0

Exploit: Centre does not check that a user is logged in and has sufficient 
permissions to perform admin tasks. An example of this can be seen when 
attempting to create a new account:

http://demo.miller-group.net/index.php?modfunc=create_account&staff&username=admin&staff_id=new

However this problem exists at almost every level within the software. There 
are also poor checks carried out when passing user data which could lead to 
SQL injection problems. There is a more serious problem within modules.php, 
there is *no checking on the path of the module and could lead to PHP 
injection.

Modules.php?modname=../../../MyCode/Stuff.php

Fix: Disable centre until an update is released (the problems are too 
extensive).
