Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS : Prometheus Alertmanager vulnerability (USN-6935-1)

medium Nessus Plugin ID 204925

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6935-1 advisory.

 It was discovered that prometheus-alertmanager didn't properly sanitize

 input it received through an API endpoint. An attacker with permission to

 send requests to this endpoint could potentially inject arbitrary code.

 On Ubuntu 20.04 LTS and Ubuntu 22.04 LTS, this vulnerability is only

 present if the UI has been explicitly activated.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected golang-github-prometheus-alertmanager-dev and / or prometheus-alertmanager packages.
