A vulnerability has been discovered in the Highslide JS component for Joomla!, which can be exploited by malicious people to disclose sensitive information.
Input passed via the "controller" parameter to index.php (when "option" is set to "com_hsconfig") is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal sequences and URL-encoded NULL bytes.
The vulnerability is confirmed in version 2.0.9. Other versions may also be affected.
Solution: Edit the source code to ensure that input is properly verified.
