Title: Alibaba Nacos访问控制错误漏洞

Description:

nacos是中国阿里巴巴（Alibaba）的一个动态服务发现、配置和服务管理平台。该软件支持基于DNS和基于RPC的服务发现，可提供提供实时健康检查，阻止服务向不健康的主机或服务实例发送请求等功能。

在版本1.4.1之前的Nacos中，ConfigOpsController允许用户执行管理操作，例如查询数据库，甚至清除数据库。虽然/data/remove端点使用@Secured注解得到了正确的保护，但是/derby端点未受保护，未经身份验证的攻击者可利用该漏洞公开访问。

Severity: 中

CVE-2021-29442 (GCVE-0-2021-29442)

Vulnerability from cvelistv5

Published

Modified

2024-08-03 22:02

Severity ?

8.6 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N

CWE

CWE-306 - Missing Authentication for Critical Function

Summary

Nacos is a platform designed for dynamic service discovery and configuration and service management. In Nacos before version 1.4.1, the ConfigOpsController lets the user perform management operations like querying the database or even wiping it out. While the /data/remove endpoint is properly protected with the @Secured annotation, the /derby endpoint is not protected and can be openly accessed by unauthenticated users. These endpoints are only valid when using embedded storage (derby DB) so this issue should not affect those installations using external storage (e.g. mysql)
