Linux Distros Unpatched Vulnerability : CVE-2026-32633

critical Nessus Plugin ID 302927

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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. (CVE-2026-32633)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
