Language:

Synopsis

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

Description

The version of ansible installed on the remote host is prior to 2.9.23-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2ANSIBLE2-2023-001 advisory.

- A flaw was found in Ansible, where a user's controller is vulnerable to template injection. This issue can occur through facts used in the template if the user is trying to put templates in multi-line YAML strings and the facts being handled do not routinely include special template characters. This flaw allows attackers to perform command injection, which discloses sensitive information. The highest threat from this vulnerability is to confidentiality and integrity. (CVE-2021-3583)

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 ansible' to update your system.
