include $doc_directory.$path_sw."lib_up_file/lib_file.php"; include $doc_directory.$path_sw."lib_up_file/lib_form_file.php"; include $doc_directory.$path_sw."lib_up_file/lib_read_file.php"; include $doc_directory.$path_sw."lib_up_file/lib_page_file.php"; include $doc_directory.$path_sw."lib_up_file/find_file.php"; include $doc_directory.$path_sw."lib_up_file/down_stat.php";

Input passed to the "$doc_directory" parameter in file.php is not properly verified before being used. This can be exploited to execute arbitrary PHP code by including files from local or external resources.

Also affected files on Files:

sw/lib_user/find_user.php sw/lib_user/lib_user.php sw/lib_user/lib_form_user.php sw/lib_user/user.php sw/lib_session/find_session.php sw/lib_session/session.php sw/lib_comment/comment.php sw/lib_comment/lib_comment.php etc..
