Maccms 10 allows remote attackers to execute arbitrary PHP code by entering this code in a template/default_pc/html/art Edit action. This occurs because template rendering uses an include operation on a cache file, which bypasses the prohibition of .php files as templates.
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).
