Summary Microsoft has addressed an authorization misconfiguration for multi-tenant applications that use Azure AD, initially discovered by Wiz, and reported to Microsoft, that impacted a small number of our internal applications. The misconfiguration allowed external parties read and write access to the impacted applications. Microsoft immediately corrected the misconfiguration and added additional authorization checks to address the issue and confirmed that no unintended access had occurred.

**漏洞简单描述：
Nacos是一套帮助发现、配置和管理微服务的程序。提供一组简单易用的特性集，能够快速的实现动态服务发现、服务配置、服务元数据以及流量管理。

2020年12月29日，Nacos官方在github发布的issue中披露Alibaba Nacos 存在一个由于不当处理User-Agent导致的未授权访问漏洞 。通过该漏洞，攻击者可以进行任意操作，包括创建新用户并进行登录后操作。

https://github.com/alibaba/nacos/issues/1105

在Nacos 2.0版本存在未授权访问漏洞，程序未有效对于用户权限进行判断，导致能够添加任意用户、修改任意用户密码等等问题。

危害等级：高危

影响范围 : Nacos <= 2.0.0-ALPHA.1

*1. 漏洞环境查找：

直接使用fofa、hunter、zoomeye等公网环境，虽然公网环境的nacos 不是很多。但是存在漏洞的环境还不少。 我这里用的是hunter，title="nacos" 就可以直接使用。

*2.然后使用google hackbar发送数据包：
POC：
http://IP:端口/nacos/v1/auth/users?pageNo=1&pageSize=9

密码很慢解密，后期利用方法可以使用添加账号、修改账号poc。此类poc公网环境测试风险比较大。
