### 简要描述：
存储型XSS可以盲打后台~
### 详细说明：
/lib/table/stats.php 13行getbot函数：
```
public static function getbot() {
$ServerName = $_SERVER["SERVER_NAME"];
$ServerPort = $_SERVER["SERVER_PORT"];
$ScriptName = $_SERVER["SCRIPT_NAME"];
$QueryString = $_SERVER["QUERY_STRING"];
$serverip = $_SERVER["REMOTE_ADDR"];
$GetLocationURL=self::geturl();
$agent1 = $_SERVER["HTTP_USER_AGENT"];
$agent=strtolower($agent1);
$Bot="";
if(strpos($agent,"googlebot")>-1) {
$Bot = "Google";
}
if(strpos($agent,"mediapartners-google")>-1) {
$Bot = "Google Adsense";
}
if(strpos($agent,"baiduspider")>-1) {
$Bot = "Baidu";
}
if(strpos($agent,"sogou")>-1) {
$Bot = "Sogou";
}
if(strpos($agent,"yahoo")>-1) {
$Bot = "Yahoo!";
}
if(strpos($agent,"msn")>-1) {
$Bot = "MSN";
}
if(strpos($agent,"soso")>-1) {
$Bot = "Soso";
}
if(strpos($agent,"iaarchiver")>-1) {
$Bot = "Alexa";
}
if(strpos($agent,"sohu")>-1) {
$Bot = "Sohu";
}
if(strpos($agent,"sqworm")>-1) {
$Bot = "AOL";
}
if(strpos($agent,"yodaobot")>-1) {
$Bot = "Yodao";
}
if(strpos($agent,"iaskspider")>-1) {
$Bot = "Iask";
}
if(strlen($Bot)>0 &&!front::get('admin_dir')) {
$stats = self::getInstance();
$insert = $stats->rec_insert(array('bot'=>$Bot,'url'=>$GetLocationURL,'ip'=>$serverip,'time'=>date('Y-m-d H:i:s')));
}
}
```
直接将$GetLocationURL插入数据库，我们看看$GetLocationURL从哪来的，geturl()函数：
```
public static function geturl() {
if(!empty($_SERVER["REQUEST_URI"])) {
$scrtName = $_SERVER["REQUEST_URI"];
$nowurl = $scrtName;
}else {
$scrtName = $_SERVER["PHP_SELF"];
if(empty($_SERVER["QUERY_STRING"])) {
$nowurl = $scrtName;
}else {
$nowurl = $scrtName."?".$_SERVER["QUERY_STRING"];
}
}
return (isset($_SERVER["HTTPS"])&&$_SERVER["HTTPS"] == "on")?'https://':'http://'.$_SERVER['HTTP_HOST'].$nowurl;
}
```
直接获取的PHP_SELF和QUERY_STRING，没有进行过滤。
前面的360webscan也只是过滤了$_GET和$_POST等变量，没有过滤$_SERVER，可造成XSS盲打后台。
### 漏洞证明：
向index.php发送数据包：

注意要设置User-Agent为百度蜘蛛或其他robot。
然后后台管理员浏览“营销”->“蜘蛛统计”时即会中招：

可进行后台盲打！
