DESCRIPTION:
EcHoLL has reported a vulnerability in the JA Showcase component for
Joomla, which can be exploited by malicious people to conduct SQL
injection attacks.

Input passed to the "catid" parameter in index.php (when "option" is
set to "com_jashowcase" and "view" is set to "jashowcase") is not
properly sanitised before being used in an SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
