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)

private function _xss_check() {
static $check = array('"', '>', '<', ''', '(', ')', 'CONTENT-TRANSFER-ENCODING');
if(isset($_GET['formhash']) && $_GET['formhash'] !== formhash()) {

}
if($_SERVER['REQUEST_METHOD'] == 'GET' ) {

$temp = $_SERVER['REQUEST_URI'].file_get_contents('php://input');
} else {

}
if(!empty($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'])));
if(strpos($temp, '<') !== false || strpos($temp, '"') !== false || strpos($temp, 'CONTENT-TRANSFER-ENCODING') !== false) {
system_error('request_tainting');
}
return true;
}
pyt:
源码由此可见discuz禁止了：
单双引号，括号，CONTENT-TRANSFER-ENCODING，尖括号等，这些字符是不能出现在用户名或密码中的哦 |
