Directory traversal vulnerability in templates/mytribiqsite/tribal-GPL-1066/includes/header.inc.php in Tribiq CMS 5.0.10a, when register_globals is enabled and magic_quotes_gpc is disabled, allows remote attackers to include and execute arbitrary local files via directory traversal sequences in the template_path parameter.  NOTE: it was later reported that this issue also affects 5.0.12c.
