Directory traversal vulnerability in includes/search/search_mdforum.php in MAXdev MDForum 2.0.1 and earlier, when magic_quotes_gpc is disabled and register_globals is enabled, allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in the PNSVlang cookie to error.php, as demonstrated by injecting PHP sequences into an Apache HTTP Server log file, which is then included by error.php.

SQL injection vulnerability in the MDForum module 2.x through 2.07 for MAXdev MDPro allows remote attackers to execute arbitrary SQL commands via the c parameter to index.php.
