Discuz“您当前的访问请求当中含有非法字符“的解决方法
故障描述:
退出登录时出现”您当前的访问请求当中含有非法字符,已经被系统拒绝“错误。如下图:
解决方法:
打开 \source\class\discuz\discuz_application.php 文件
找到 - 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 修改为 - 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;
- }
