	author...: EgiX
	mail.....: n0b0d13s[at]gmail[dot]com
	
	link.....: http://linpha.sourceforge.net
	details..: works with magic_quotes_gpc = off

	[-] LFI found by rgod in /plugins/maps/map.main.class.php

	20.	if(!defined('TOP_DIR')) { define('TOP_DIR','../'); }
	21.	
	22.	$type = read_config('maps_type');
	23.	
	24.	require_once(TOP_DIR."/plugins/maps/$type/$type.class.php"); <== LFI
	25.	require_once(TOP_DIR.'/plugins/maps/geocode.class.php');
	26.	include_once(TOP_DIR.'/plugins/maps/location.class.php');

	an attacker could be include an arbitrary local file through the require_once() at
	line 24 cause is possible to modify 'maps_type' config value by another script:

	[-] look at /plugins/maps/db_handler.php

	112.	if(@	$_POST['job'] == "settings") 
	113.	{
	114.	update_config($_POST['maps_yahoo_id'], 'maps_yahoo_id' );
	115.	update_config($_POST['maps_google_key'], 'maps_google_key');
	116.	update_config($_POST['maps_type'], 'maps_type');			<== 'maps_type' value updating
	117.	update_config($_POST['maps_display_type'], 'maps_display_type');
	118.	update_config($_POST['maps_google_ctrl_size'], 'maps_google_ctrl_size');
	119.	update_config($_POST['maps_default_zoom'], 'maps_default_zoom');
	120.	update_config($_POST['maps_default_zoom_location'], 'maps_default_zoom_location');
	121.	update_config($_POST['maps_yahoo_type_control'], 'maps_yahoo_type_control');
	122.	update_config($_POST['maps_yahoo_pan_control'], 'maps_yahoo_pan_control');
	123.	update_config($_POST['maps_yahoo_slide_control'], 'maps_yahoo_slide_control'); 
	124.	update_config($_POST['maps_marker_auto_popup'], 'maps_marker_auto_popup'); 
	125.	
	126.	header("Location: ".TOP_DIR."/admin.php?page=maps&plugins=1");
	127.	}

	and now we need a file to include...what do you think about ChangeLog?

	[-] ChangeLog file:
