Discuz! X3.1 正式版含目前最新版[2014-03-01]在用户退出时偶尔会提示如下错误,特别是数据整合后的站点.
错误代码:
Discuz! System Error 您当前的访问请求当中含有非法字符,已经被系统拒绝.
- PHP Debug
- [Line: 0022]search.php(discuz_application->init)
- [Line: 0071]sourceclassdiscuzdiscuz_application.php(discuz_application->_init_misc)
- [Line: 0552]sourceclassdiscuzdiscuz_application.php(discuz_application->_xss_check)
- [Line: 0355]sourceclassdiscuzdiscuz_application.php(system_error)
- [Line: 0017]sourcefunctionfunction_core.php(discuz_error::system_error)
- [Line: 0024]sourceclassdiscuzdiscuz_error.php(discuz_error::debug_backtrace)
临时解决方法:
修改 sourceclassdiscuz下的discuz_application.php文件大约第350行的private function _xss_check()方法,代码如下:
- 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 = $_SERVER['REQUEST_URI'];
- } elseif(emptyempty ($_GET['formhash'])) {
- $temp = $_SERVER['REQUEST_URI'].file_get_contents('php://input');
- } else {
- $temp = '';
- }
- if(!emptyempty($temp)) {
- $temp = strtoupper(urldecode(urldecode($temp)));
- foreach ($check as $str) {
- if(strpos($temp, $str) !== false) {
- system_error('request_tainting');
- }
- }
- }
- return true;
- }
- //为
- private function _xss_check() {
- $temp = strtoupper(urldecode(urldecode($_SERVER['REQUEST_URI'])));//开源软件:Vevb.com
- if(strpos($temp, '<') !== false || strpos($temp, '"') !== false || strpos($temp, 'CONTENT-TRANSFER-ENCODING') !== false) {
- system_error('request_tainting');
- }
- return true;
- }
