  application: clansys 1.1
  description: a php / mysql based clan content management system
     download:
http://www.clanscripte.net/main.php?content=download&do=file&dlid=113
  description: you can get each password with a simple sql injection. the
password 
               is base64 encoded, but it's easy to decode, that means, you
will get
			   the password in plaintext :)
  fingerprint: google -> "Clansys  v.1.1" -> 4'030
               msn -> "Clansys  v.1.1" ->  529
   conditions: 
       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.


---------------------------- member.php - line 180
-------------------------------------
$sql = "SELECT * FROM member WHERE id=$showid";
-----------------------------------------------------------------------------------------

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