emmm这次镜像拖了很久。。。#Symfonos2

首先上nmap结果：

可以看到开放了21，22，80，139，445端口，开放了139和445意味着有smb可以探测，直接上enum4linux

p2

可以看到空密码。。。
直接smbclient连接

p3

直接看到有个anonymous文件夹

p4

拿下日志文件，查看一番发现用户名aeolus,尝试ftp以及ssh密码爆破。。。爆破ssh密码为sergioteamo
直接连接以后发现还开放其他端口

p5

外面没扫到8080,应该是http服务，所以可以直接找找漏洞。。。
这里肯定要做所谓的端口转发，端口转发分本地端口转发以及远程端口转发，区别在于ssh连接以及转发的服务连接方向是否一致，一致则为本地端口转发。
这里命令如下：

ssh -L 7001:localhost:8080 [email protected]

7001为我的端口，8080为对面端口。

p6

这里直接访问7001端口就能转发了。

p7

这里librenms cms有漏洞，可参考( https://www.anquanke.com/post/id/169295)
这里登录账号密码同ssh,aeolus:sergioteamo

p8

p9

然后尝试提权，先sudo -l看看有哪些特权程序

p10

这样直接uuid提权

p11

p12

The end...
