Vulnerability Title
Glances's Browser API Exposes Reusable Downstream Credentials via `/api/4/serverslist`
Source: CVE Program / CVE List V5
Vulnerability Description
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.
