Hack The Box —— Bank


Hack The Box —— Bank

信息搜集

nmap

nmap -T4 -A -v 10.10.10.29

扫描结果

发现开放了22、80、TCP 53 端口,在 53 端口上开放 DNS 服务。通常情况下 DNS 服务开放在 UDP 53 端口上,在 TCP 上开放 DNS 服务,一般是具有区域传输功能,因此怀疑具有 DNS 区域传输漏洞。

访问 80 端口,是一个 apache 的默认页面,通常情况下,这种既开着 DNS 的,然后直接访问 80 端口为空页面的服务器,是作为虚拟主机使用。

DNS 信息查询


首先测试 localhost 与 10.10.10.29,并未发现有价值的信息,然后尝试猜测 bank.htb (看了 WP 才知道),发现该域名能够被 DNS 服务所解析,因此利用 dig 工具进行进一步测试。

dig axfr bank.htb @10.10.10.29

成功利用区域传输漏洞获得 bank.htb 域名的子域名。

漏洞发掘

将攻击机的 DNS 服务器设置为 10.10.10.29,然后访问 www.bank.htb,得到:

然后利用 dirsearch 工具进行目录爆破:

发现上传目录、index.php、support.php,但是index.phpsupport.php页面大小不同,却直接 302 重定向到login.php,怀疑index.phpsupport.php 另有玄机。

利用 burpsuite 的重写 response header 的功能,取消重定向,即将 302 改为 200

访问得到index.phpsupport.php

support.php 存在上传点,但是经过尝试,并未绕过限制,进而进一步进行测试。

在目录爆破的过程中,发现了 balance-transfer 目录,访问后得到:

随便打开一个文件,发现里面疑似是加密过的日志,因此尝试寻找加密失败的文件,进而获得用户名和密码的明文。

首先将所有文件下载到本地:

wget -r http://www.bank.htb/balance-transfer

然后进入到 balance-transfer 目录,删除index.html* 等文件,进行大小排序:

wc -c *.acc | sort -n

发现一个特别小的文件,访问后得到:

利用得到的账号和密码登录:

再次发现上传页面,同时,该上传页面利用的是之前的 support.php

右键查看当前页面的源代码,发现一处 debug 留下的漏洞:

直接上传webshell,命名为 xxx.htb,菜刀连接:

查看 user.txt 获得第一个 flag。

whoami 查看权限,发现权限不足,尝试提权。

上传 LinEnum.sh 脚本,并执行,获得一些辅助信息。
