Glances's Browser API Exposes Reusable Downstream Credentials via `/api/4/serverslist`

Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.2, in Central Browser mode, the `/api/4/serverslist` endpoint returns raw server objects from `GlancesServersList.get_servers_list()`. Those objects are mutated in-place during background polling and can contain a `uri` field with embedded HTTP Basic credentials for downstream Glances servers, using the reusable pbkdf2-derived Glances authentication secret. If the front Glances Browser/API instance is started without `--password`, which is supported and common for internal network deployments, `/api/4/serverslist` is completely unauthenticated. Any network user who can reach the Browser API can retrieve reusable credentials for protected downstream Glances servers once they have been polled by the browser instance. Version 4.5.2 fixes the issue.

信息暴露

glances 安全漏洞

glances是Nicolas Hennion个人开发者的一款系统监测工具。 glances 4.5.2之前版本存在安全漏洞，该漏洞源于Central Browser模式下/api/4/serverslist端点未经身份验证返回包含嵌入式HTTP基本凭据的服务器对象，可能导致网络用户检索受保护下游服务器的可重用凭据。
