Multiple bugs in TFT-Gallery

Script Name: TFT-Gallery
Authors: Mike Scalora, Eric Thelin, Sascha Lorenz & Jan Berndt
Website: http://tftgallery.sourceforge.net
Bug Report: NetJackal (nj[AT]hackerz[DOT]ir & nima_501[AT]yahoo[DOT]com)
Status: Patch not released

First i should apologize for my bad english.

Intro:
TFT-Gallery is a PHP-based Web image gallery & does n't require databse.

Bugs Description:
First bug)
Look at admin`s index page(/admin/index.php)

    if(file_exists("passwd")) {
                    $fd = fopen("passwd", "r");
                    $givenpw = fgets($fd,15);
                    fclose($fd);
                    if(isset($_REQUEST['password']) and
                            isset($_REQUEST['username']) and
                                    $_REQUEST['username']=='admin' and
                                            crypt($_REQUEST['password'], "tftgallery") ==

$givenpw) {
$_SESSION['admin']=true;
} else {
include_once "login_form.inc";
exit;
}
}

    TFT-Gallery stores admin's password in "passwd" file at admin folder, so everyone has access

to it by going to:

http://victim/admin/passwd
TIP: Password hashed by DES algorithm.
TIP: Username is "admin".
Second Bug)
TFT-Gallery doesn't check file extension so if somebody who has gain access by First bug can
upload any file extension (ex. evil.php).

Solution:
Edit code and store passwd some where else (out of wwwroot).
