開啟：

\source\class\discuz的discuz_application.php尋找

private function _xss_check() {                static $check = array('"', '>', '<', '\'', '(', ')', 'CONTENT-TRANSFER-ENCODING');                if(isset($_GET['formhash']) && $_GET['formhash'] !== formhash()) {                        system_error('request_tainting');                }                if($_SERVER['REQUEST_METHOD'] == 'GET' ) {                        $temp = $_SERVER['REQUEST_URI'];                } elseif(empty ($_GET['formhash'])) {                        $temp = $_SERVER['REQUEST_URI'].file_get_contents('php://input');                } else {                        $temp = '';                }                if(!empty($temp)) {                        $temp = strtoupper(urldecode(urldecode($temp)));                        foreach ($check as $str) {                                if(strpos($temp, $str) !== false) {                                        system_error('request_tainting');                                }                        }                }                return true;

修改為：

private function _xss_check() {                $temp = strtoupper(urldecode(urldecode($_SERVER['REQUEST_URI'])));                if(strpos($temp, '<') !== false || strpos($temp, '"') !== false || strpos($temp, 'CONTENT-TRANSFER-ENCODING') !== false) {                        system_error('request_tainting');                }                return true;        }
