Joomla Component (com_content) -  Blind SQL Injection Vulnerability




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

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




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--

[x] Demo :
