Amazon Linux 2 : ecs-init (ALASECS-2024-031)

critical Nessus Plugin ID 187774

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of ecs-init installed on the remote host is prior to 1.79.1-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2024-031 advisory.

Text nodes not in the HTML namespace are incorrectly literally rendered, causing text which should be escaped to not be. This could lead to an XSS attack. (CVE-2023-3978)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update ecs-init' to update your system.
