DESCRIPTION:
A vulnerability has been discovered in the Percha Multicategory
Article 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_perchacategoriestree") 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 confirmed in version 0.6. Other versions may
also be affected.

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