Discuz退出登陆报错Discuz! System Error

发布日期:2019-07-10 22:22:17 来源:CSS5

QQ退出登陆Discuz,或直接登陆Discuz后退出登陆出现报错解决方法,遇到报错版本Discuz 3.2X。

接着退出的时候点了下清除痕迹就报错如下:

退出登陆错误正文:

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: 0026]member.php(discuz_application->init)
[Line: 0071]source/class/discuz/discuz_application.php(discuz_application->_init_misc)
[Line: 0552]source/class/discuz/discuz_application.php(discuz_application->_xss_check)
[Line: 0355]source/class/discuz/discuz_application.php(system_error)
[Line: 0023]source/function/function_core.php(discuz_error::system_error)
[Line: 0024]source/class/discuz/discuz_error.php(discuz_error::debug_backtrace)

报错问题解决方法:

source\class\discuz\discuz_application.php

找到:private function _xss_check()

大概在350行左右:

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;
}

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;
}
