Joomla JE Ajax Event Calendar Component "view" File Inclusion Vulnerability

SECUNIA ADVISORY ID:
SA39836

VERIFY ADVISORY:
http://secunia.com/advisories/39836/

DESCRIPTION:
Valentin Hoebel has reported a vulnerability in the JE Ajax Event
Calendar component for Joomla, which can be exploited by malicious
people to disclose potentially sensitive information.

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.

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

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

PROVIDED AND/OR DISCOVERED BY:
Valentin Hoebel
