解决方法：

131122 <wbr> <wbr>source\class\discuz\discuz_application.php <wbr> <wbr> private function _xss_check()

350行左右

1. private function _xss_check() {

2. static $check = array('"', '>', '<', ''', '(', ')', 'CONTENT-TRANSFER-ENCODING');

3. if(isset(_GET['formhash'] !== formhash()) {

4. system_error('request_tainting');

5. }

6. if($_SERVER['REQUEST_METHOD'] == 'GET' ) {

7. _SERVER['REQUEST_URI'];

8. } elseif(empty ($_GET['formhash'])) {

9. _SERVER['REQUEST_URI'].file_get_contents('php://input');

10. } else {

11. $temp = '';
