### 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： [<img src="https://images.seebug.org/upload/201407/23003841594e3fa36a335ccb96106ab393eebe12.jpg" alt="07.jpg" width="600" onerror="javascript:errimg(this);">](https://images.seebug.org/upload/201407/23003841594e3fa36a335ccb96106ab393eebe12.jpg) 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： [<img src="https://images.seebug.org/upload/201407/23004116d706176853967805c1eeeb1095680e9d.jpg" alt="08.jpg" width="600" onerror="javascript:errimg(this);">](https://images.seebug.org/upload/201407/23004116d706176853967805c1eeeb1095680e9d.jpg) 可进行后台盲打！
