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;
[*] }
复制代码
或使用官方方法解决:http://www.discuz.net/thread-3485502-1-1.html
上传覆盖同名文件,后台更新缓存,重新登录退出看看是否解决了。
