Two vulnerabilities have been reported in the RSComments component for Joomla, which can be exploited by malicious people to conduct script insertion attacks.
Input passed via the "website" and "name" parameters to index.php (when "option" is set to "com_rscomments") when posting a comment is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
The vulnerabilities are reported in version Rev 2. Other versions may also be affected.
Solution: Update to version Rev 3.
