DESCRIPTION:
Two vulnerabilities have been reported in the K2 component for
Joomla!, which can be exploited by malicious people to conduct script
insertion attacks.

Input passed via the "Name" and "Website" fields when making a
comment is not properly sanitised before being used. This can be
exploited to insert arbitrary HTML and script code which will get
executed in a user's browser session when the malicious data is being
viewed.

The vulnerabilities are reported in versions prior to 2.4.

SOLUTION:
Update to version 2.4 or greater.
