Ansible developers report :

Templating engine fix for not preserving usnafe status when trying to preserve newlines.

The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:2663 advisory.

    Ansible is a simple model-driven configuration management, multi-node     deployment, and remote-task execution system. Ansible works over SSH and     does not require any software or daemons to be installed on remote nodes.
    Extension modules can be written in any language and are transferred to     managed machines automatically.

    The following packages have been upgraded to a newer upstream version:
    ansible (2.9.23)

    Bug Fix(es):
    * CVE-2021-3583 ansible: Template Injection through yaml multi-line strings     with ansible facts used in template.

    See:
    https://github.com/ansible/ansible/blob/v2.9.23/changelogs/CHANGELOG-v2.9.rst     for details on bug fixes in this release.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5315-1 advisory.

    It was discovered that Ansible did not properly manage directory permissions when running playbooks with     an unprivileged become user. A local attacker could possibly use this issue to cause a race condition,     escalate privileges and execute arbitrary code. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04     ESM and Ubuntu 20.04 ESM. (CVE-2020-1733)

    It was discovered that the fix to address CVE-2020-1733 in Ansible was incomplete on systems using ACLs     and FUSE filesystems. A local attacker could possibly use this issue to cause a race condition, escalate     privileges and execute arbitrary code. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 ESM and     Ubuntu 20.04 ESM. (CVE-2020-10744)

    It was discovered that Ansible did not properly manage multi-line YAML strings and special template     characters. A local attacker could possibly use this issue to cause a template injection, resulting in the     disclosure of sensitive information or other unspecified impact. (CVE-2021-3583)

    It was discovered that the ansible-connection module in Ansible did not properly manage certain error     messages. A local attacker could possibly use this issue to expose sensitive information. This issue only     affected Ubuntu 20.04 ESM and Ubuntu 22.04 ESM. (CVE-2021-3620)

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

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

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)

The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3178-1 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)

  - A flaw was found in the Ansible Engine 2.9.18, where sensitive info is not masked by default and is not     protected by the no_log feature when using the sub-option feature of the basic.py module. This flaw allows     an attacker to obtain sensitive information. The highest threat from this vulnerability is to     confidentiality. (CVE-2021-20228)

  - A flaw was found in several ansible modules, where parameters containing credentials, such as secrets,     were being logged in plain-text on managed nodes, as well as being made visible on the controller node     when run in verbose mode. These parameters were not protected by the no_log feature. An attacker can take     advantage of this information to steal those credentials, provided when they have access to the log files     containing them. The highest threat from this vulnerability is to data confidentiality. This flaw affects     Red Hat Ansible Automation Platform in versions before 1.2.2 and Ansible Tower in versions before 3.8.2.
    (CVE-2021-3447)

  - 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)

  - A flaw was found in Ansible Engine's ansible-connection module, where sensitive information such as the     Ansible user credentials is disclosed by default in the traceback error message. The highest threat from     this vulnerability is to confidentiality. (CVE-2021-3620)
