### 一

拿到一个非法网站，随即进行信息收集，很舒服的找到了后台

我他喵上来就是一手弱口令 admin/123456  
一发入魂  
很快啊，找到一个可以上传的点

我先冲一手

没有后缀检测，有文件头检测，直接一波zip格式拿下  
开开心心去连接蚁剑

上线上线  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-a8170f71f137569cfabae91656c2ce86eb39eca0.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-a8170f71f137569cfabae91656c2ce86eb39eca0.png)  
没有杀软，上来就是一个烂土豆提权  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-35ea3e3c5e54e55821f07cb960c5c18c1ab7e854.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-35ea3e3c5e54e55821f07cb960c5c18c1ab7e854.png)  
查看没有域，并且没有内网ip

### 二

打算创一个影子用户  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-e46aa6fe9afa55aabaf071703ea46fc83122fc91.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-e46aa6fe9afa55aabaf071703ea46fc83122fc91.png)  
可以看到net user查看不了添加的影子用户，但是用户组能看，我们可以3389进去修改注册表  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-bd6267c63c33881d1ee39f63547a8049049a19cb.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-bd6267c63c33881d1ee39f63547a8049049a19cb.png)  
修改注册表  
选择SAM 项 ，在工具栏上的 编辑 &gt; 权限 中设置权限 ，将 Administrators组 的权限设置为完全控制 后保存  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-b7f2b34fb33b36045adfffa1d299d5bf8b22d969.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-b7f2b34fb33b36045adfffa1d299d5bf8b22d969.png)  
az，3389经常断，烦！  
溜了溜了，经常断开。  
后续我在自己本地试一试，  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-6533348fd590423544fa4eb16d88e190c611bf07.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-6533348fd590423544fa4eb16d88e190c611bf07.png)

设置好后，，发现SAM项下出现了隐藏的子项  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-506acd964c730261693a95838a40a1db22438742.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-506acd964c730261693a95838a40a1db22438742.png)  
找到Administrator的SID，复制  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-8317ecf622966e174423d603097d359e97ee47e4.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-8317ecf622966e174423d603097d359e97ee47e4.png)  
帮刚才复制的给影子用户F值  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-933bd98923244619c7b869f3923a1bb80e5c4a6f.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-933bd98923244619c7b869f3923a1bb80e5c4a6f.png)  
然后导出Users下对应fuckadmin1234$项  
再导出Names下fuckadmin1234$  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-c419c0eeaa60f5c7ddf535caf704a96661da12f2.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-c419c0eeaa60f5c7ddf535caf704a96661da12f2.png)

`net user fuckadmin1234$ /del`  
删掉fuckadmin1234$  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-74725ca9ba81edcf2276a2a19d6ead4e9cad8686.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-74725ca9ba81edcf2276a2a19d6ead4e9cad8686.png)  
没有这个用户了  
这时候我们再导入注册表  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-fd399ddad86f2fd5d60be816b3ee27118029f994.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-fd399ddad86f2fd5d60be816b3ee27118029f994.png)

用户组里面已经没有了  
[![](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-22f288b7e08b17c09c9f7a6e045bc69b2e774ffc.png)](https://shs3.b.qianxin.com/attack_forum/2021/07/attach-22f288b7e08b17c09c9f7a6e045bc69b2e774ffc.png)  
这样就可以登陆RDP了
