当前大量开发人员使用git进行版本控制,对站点自动部署。 如果配置不当,可能会将.git文件夹直接部署到线上环境。这就引起了git泄露漏洞。
GitHack是一个.git泄露利用脚本,通过泄露的.git文件夹下的文件,还原重建工程源代码。
渗透测试人员、攻击者,可以进一步审计代码,挖掘:文件上传,SQL注射等安全漏洞。
脚本的工作原理:
- 解析.git/index文件,找到工程中所有的: ( 文件名,文件sha1 )
- 去.git/objects/ 文件夹下下载对应的文件
- zlib解压文件,按原始的目录结构写入源代码
它的优点:
- 速度快,默认20个工作线程
- 尽量还原所有的源代码,缺失一部分文件不影响脚本工作
- 脚本不需要执行额外的git命令,All you need is python
- 脚本无需浏览目录
可能的改进:
存在文件被gc打包到git\objects\pack的情况,稍后可测试下看能否直接获取并解压这个文件,还原源代码

非常感谢 sbp 的 gin – a Git index file parser,脚本中使用了他的解析源代码,为适用python 2.x和Windows作了细微的改动
不错
恢复大文件(100M+)的时候会一直卡住。
好可怕,不过一般很少人会把.git暴露出来吧。
不错
