Multiple vulnerabilities have been reported in the JE Ajax Event Calendar component for Joomla, which can be exploited by malicious people to disclose potentially sensitive information and conduct SQL injection attacks.

1) Input passed to the "view" parameter in index.php (when "option" is set to "com_jeajaxeventcalendar") is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and URL-encoded NULL bytes.

This vulnerability is reported in version 1.0.1. Other versions may also be affected.

2) Input passed to the "event_id" parameter in index.php (when "option" is set to "com_jeajaxeventcalendar" and "view" is set to "alleventlist_more") is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
