查找如下代码（在360行左右），并替换

1. private function _xss_check() {
   
2. static $check = array('"', '>', '<', '\'', '(', ')', 'CONTENT-TRANSFER-ENCODING');
   
3. if(isset($_GET['formhash']) && $_GET['formhash'] !== formhash()) {
   
4. system_error('request_tainting');
   
5. }
   
6. if($_SERVER['REQUEST_METHOD'] == 'GET' ) {
   
7. $temp = $_SERVER['REQUEST_URI'];
   
8. } elseif(empty ($_GET['formhash'])) {
   
9. $temp = $_SERVER['REQUEST_URI'].file_get_contents('php://input');
   
10. } else {
    
11. $temp = '';
    
12. }
    
13. if(!empty($temp)) {
    
14. $temp = strtoupper(urldecode(urldecode($temp)));
    
15. foreach ($check as $str) {
    
16. if(strpos($temp, $str) !== false) {
    
17. system_error('request_tainting');
    
18. }
    
19. }
    
20. }
    
21. return true;
    
22. }

替换为：

1. private function _xss_check() {
   
2. $temp = strtoupper(urldecode(urldecode($_SERVER['REQUEST_URI'])));
   
3. if(strpos($temp, '<') !== false || strpos($temp, '"') !== false || strpos($temp, 'CONTENT-TRANSFER-ENCODING') !== false) {
   
4. system_error('request_tainting');
   
5. }
