----- Original Message -----
> =================================================================================
> Joomla! 1.7.0-RC and lower | Multiple Cross Site Scripting (XSS)
> Vulnerabilities
> =================================================================================
> 
> 
> 1. OVERVIEW
> 
> Joomla! 1.7.0-RC and versions of 1.6.x are 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, Request URI) 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-RC and all versions of 1.6.x
> 
> 
> 5. PROOF-OF-CONCEPT/EXPLOIT
> 
> 
> component: com_search, parameter: searchword (Browser: IE, Konqueror)
> =====================================================================
> N.B. Our previous reported issue (1.6.3) of "searchword" parameter XSS
> was not fixed completely.
