该问题的根因是msf的监听(handler)对互联网开放后,被互联网上的扫描器(网络测绘)扫描后产生大量失效的tcp连接,导致出现问题

该问题可以自行手动复现

  • 首先在VPS上搭建viper
  • 创建一个reverse_tcp类型的监听,端口为4999,假设vps ip为123.123.123.123

  • 在另外一台linux上运行hping3 --flood -S -p 4999 123.123.123.123,针对监听进行tcp flood测试
  • 大概经过20秒之后,问题出现,渗透测试服务不可用

当前时间点看这个问题没有解决方案,只能通过使用reverse_http/使用不常用端口等方式进行缓解
