FreeBSD : Prometheus -- arbitrary redirects (59ab72fb-bccf-11eb-a38d-6805ca1caf5c)

medium Nessus Plugin ID 150091

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Prometheus reports :

Prometheus is an open-source monitoring system and time series database. In 2.23.0, Prometheus changed its default UI to the New ui.
To ensure a seamless transition, the URL's prefixed by /new redirect to /. Due to a bug in the code, it is possible for an attacker to craft an URL that can redirect to any other URL, in the /new endpoint.
If a user visits a prometheus server with a specially crafted address, they can be redirected to an arbitrary URL. The issue was patched in the 2.26.1 and 2.27.1 releases. In 2.28.0, the /new endpoint will be removed completely. The workaround is to disable access to /new via a reverse proxy in front of Prometheus.

Solution

Update the affected packages.
