Maccms through 8.0 allows XSS via the site_keywords field to index.php?m=system-config because of tpl/module/system.php and tpl/html/system_config.html, related to template/paody/html/vod_index.html.
Maccms 8.0 allows XSS via the inc/config/cache.php t_key parameter because template/paody/html/vod_type.html mishandles the keywords parameter, and a/tpl/module/db.php only filters the t_name parameter (not t_key).
