Joomla! contains a flaw that may allow a remote attacker to execute arbitrary commands or code. The issue is due to the '/includes/joomla.php' script not properly sanitizing user input supplied to the 'includepath' parameter. This may allow an attacker to include a file from a third-party remote host that contains commands or code that will be executed by the vulnerable script with the same privileges as the web server.
OSVDB is not aware of a solution for this vulnerability.
