Answer 1

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;
  

• }

复制代码





• 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;
  

• }
