解决方案如下:
\source\class\discuz的discuz_application.php

查找

    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;
            }


替换为:

     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;
            }
