TITLE:
Joomla GCalendar Component "controller" File Inclusion Vulnerability

SECUNIA ADVISORY ID:
SA38925

VERIFY ADVISORY:
http://secunia.com/advisories/38925/

DESCRIPTION:
A vulnerability has been discovered in the GCalendar component for
Joomla, which can be exploited by malicious people to disclose
potentially sensitive information.

Input passed to the "controller" parameter in index.php (when
"option" is set to "com_gcalendar") is not properly sanitised 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.

The vulnerability is confirmed in version 2.1.5. Other versions may
also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
