复现过程

启动环境

https://blog.csdn.net/JiangBuLiu/article/details/93853056
进入路径为

cd /root/vulhub/openssl/heartbleed

搭建及运行漏洞环境：

docker-compose build && docker-compose up -d

用时：9分钟
环境启动后，访问https://filippo.io/Heartbleed进行在线检测：

（需要公网IP，自己内网的就不用测了）

漏洞复现

Python2运行ssltest.py

python ssltest.py your-ip -p 443 

拿到敏感数据（Cookie）：

有数据时是这样：
