Hi all
I just got the ok from the client pertaining the disclosure of parts of the
code.
Basically I made admin and a user must be loged in in order to access any file
in that directory. (except index.php)
Here is the file index.php
<?php
require_once "../scripts/globals.php";
require_once "../scripts/database.php";
if(defined('DEBUG_LVL'))
error_reporting(DEBUG_LVL);
else
error_reporting(0);
function getShopDest($dest,$data)
{if( (array_key_exists('action',$data)) &&
($data['action']=='post_process'))
{if(array_key_exists('authorize',$data))
$dest=PAGE_ORDERMAN."?order=$data[authorize]&action=authorise";
elseif(array_key_exists('expedite',$data))
$dest=PAGE_ORDERMAN."?order=$data[expedite]&action=ship";
elseif(array_key_exists('deny',$data))
$dest=PAGE_ORDERMAN."?order=$data[deny]&action=deny";
elseif(array_key_exists('view',$data))
$dest=PAGE_ORDERMAN."?order=$data[view]";
}
return $dest;
}
$myDb=new verify(DB_HOST,DB_USER,DB_PASS,DB_DB);
if($myDb->LogedIn())
{$dest=PAGE_LOGIN_SUCCESS;
$dest=getShopDest($dest,$_GET);
header("Location: $dest");
die();}
$thispage=PAGE_LOGIN;
$message='';
$hiddens="\n\t";
$admin=ADMIN_STYLE;;
$old_name='';
if(array_key_exists('name',$_POST))
$old_name=htmlspecialchars($_POST['name']);
$valid=array('from','authorize','order');
#copy GET to POST
if(count($_GET)>0)
{foreach($_GET as $key=>$value)
if(in_array($key,$valid))
{$key=htmlspecialchars($key);
$value=htmlspecialchars($value);
$hiddens.=<<<___hid
<input type="hidden" name="$key" value="$value">\n\t
___hid;
}
}
elseif(count($_POST)>0)
foreach($_POST as $key=>$value)
if( ($key!=='login') && ($key!=='name') && ($key!=='pass') )
$hiddens.=<<<_hid_
<input type="hidden" name="$key" value="$value">\n\t

{safeReferer($ref,$chksum);
$hiddens.=<<<_ref_
<input type="hidden" name="referer" value="$ref">\t
\t<input type="hidden" name="checksum" value="$chksum">
_ref_;
}
if(!empty($_POST['login']))
{#process request
if(isset($_POST['login']))
if($_POST['login']=='Login')
[EMAIL PROTECTED]'name'];
[EMAIL PROTECTED]'pass'];
#encode password
$pass=sha1(crc32(md5($pass)));
if($myDb->login($name,$pass,'users',$id))
{$dest=($id==777?PAGE_ROOT_LOGIN_SUCCESS:PAGE_LOGIN_SUCCESS);
#added new destinations for the store
$dest=GetShopDest($dest,$_POST);
if( (array_key_exists('savereferer',$_POST)) &&
($_POST['savereferer']=='yes'))
$dest=safeReferer($nothing,$empty,$dest);
header("Location: $dest");
die();}
else
{$message="Invalid login";}}}
elseif(!empty($_POST['cancel']))
{if(isset($_POST['cancel']))
if($_POST['cancel']=='Cancel')
{echo PAGE_PAGESTORE;
header("Location: ".PAGE_PAGESTORE);
exit();}}
echo <<<_EMPTY_FORM

And in every file in the directory /admin, I require the file login.php
Here is the file login.php
<?php
/* Original Flavor by Straight-A-Software

*/
/* Purpose of this file login check module
Specifics: to be required on each page that requires login
This script likes PHP 4
*/

if(defined('DEBUG_LVL'))
error_reporting(DEBUG_LVL);
else
error_reporting(0);
$login_verify=new verify(DB_HOST,DB_USER,DB_PASS,DB_DB);
$verify=$login_verify->LogedIn();
if($verify===false)
{$where=AddGetVar(PAGE_LOGIN,'savereferer','yes');
header("Location: $where");
die();}
if(!defined('USER_ID')) define('USER_ID',$login_verify->userid());?>
And here are the relative parts of my database abstraction layer
(database.php)
