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 2.9.18-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2ANSIBLE2-2023-004 advisory.

- A flaw was found in ansible module where credentials are disclosed in the console log by default and not protected by the security feature when using the bitbucket_pipeline_variable module. This flaw allows an attacker to steal bitbucket_pipeline credentials. The highest threat from this vulnerability is to confidentiality. (CVE-2021-20178, CVE-2021-20180)

- A flaw was found in ansible. Credentials, such as secrets, are being disclosed in console log by default and not protected by no_log feature when using those modules. An attacker can take advantage of this information to steal those credentials. The highest threat from this vulnerability is to data confidentiality. Versions before ansible 2.9.18 are affected. (CVE-2021-20191)

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