目录扫描

gobuster dir -u http://192.168.1.190:66/ -w /opt/SecLists/Discovery/Web-Content/directory-list-2.3-medium.txt

http://192.168.1.190:66/index_files/
http://192.168.1.190:66/eon

这里扫描到了一个有用的文件

这里base64解码后可以看到一个文件和和压缩包文件头

我们将base64 转换为压缩包文件

https://base64.guru/converter/decode/file

得到了一个压缩包文件，里面存在一个文件，但是没有密码还需要对压缩包进行爆破。

使用john 爆破成功获取密码，解压后获取一个账号密码

首先使用 zip2john 从 zip 文件创建哈希
zip2john  application.zip  > hash
然后使用 john 来破解哈希值
john  -wordlist= /usr/share/wordlists/rockyou.txt hash

成功登录后台。

权限获取

这里可以看到这个版本cms，还是存在好多漏洞的

这里直接root 权限，我也是没想到

获取FLAG

End
