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.
