2. BACKGROUND

plugins that allows you to start your own favourite artist band
website. Although it is just a Joomla! plugin, it comes with full
Joolma! bundle for ease of use and installation.


3. VULNERABILITY DESCRIPTION

Multiple parameters were not properly sanitized upon submission, 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. The vulnerable plugins
include: com_find, com_charts and com_videos.
