An incomplete fix was found for the fix of the flaw CVE-2020-1733 ansible: insecure temporary directory when running become_user from become directive. The provided fix is insufficient to prevent the race condition on systems using ACLs and FUSE filesystems. Ansible Engine 2.7.18, 2.8.12, and 2.9.9 as well as previous versions are affected and Ansible Tower 3.4.5, 3.5.6 and 3.6.4 as well as previous versions are affected.

An update of the ansible package has been released.

The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1509-1 advisory.

  - A flaw was found in Ansible before version 2.2.0. The apt_key module does not properly verify key     fingerprints, allowing remote adversary to create an OpenPGP key which matches the short key ID and inject     this key instead of the correct key. (CVE-2016-8614)

  - Ansible before version 2.2.0 fails to properly sanitize fact variables sent from the Ansible controller.
    An attacker with the ability to create special variables on the controller could execute arbitrary     commands on Ansible clients as the user Ansible runs as. (CVE-2016-8628)

  - An input validation vulnerability was found in Ansible's mysql_user module before 2.2.1.0, which may fail     to correctly change a password in certain circumstances. Thus the previous password would still be active     when it should have been changed. (CVE-2016-8647)

  - Ansible before versions 2.1.4, 2.2.1 is vulnerable to an improper input validation in Ansible's handling     of data sent from client systems. An attacker with control over a client system being managed by Ansible     and the ability to send facts back to the Ansible server could use this flaw to execute arbitrary code on     the Ansible server using the Ansible server privileges. (CVE-2016-9587)

  - A flaw was found in the way Ansible (2.3.x before 2.3.3, and 2.4.x before 2.4.1) passed certain parameters     to the jenkins_plugin module. Remote attackers could use this flaw to expose sensitive information from a     remote host's logs. This flaw was fixed by not allowing passwords to be specified in the params     argument, and noting this in the module documentation. (CVE-2017-7550)

  - In ansible it was found that inventory variables are loaded from current working directory when running     ad-hoc command which are under attacker's control, allowing to run arbitrary code as a result.
    (CVE-2018-10874)

  - An incomplete fix was found for the fix of the flaw CVE-2020-1733 ansible: insecure temporary directory     when running become_user from become directive. The provided fix is insufficient to prevent the race     condition on systems using ACLs and FUSE filesystems. Ansible Engine 2.7.18, 2.8.12, and 2.9.9 as well as     previous versions are affected and Ansible Tower 3.4.5, 3.5.6 and 3.6.4 as well as previous versions are     affected. (CVE-2020-10744)

  - An Improper Output Neutralization for Logs flaw was found in Ansible when using the uri module, where     sensitive data is exposed to content and json output. This flaw allows an attacker to access the logs or     outputs of performed tasks to read keys used in playbooks from other users within the uri module. The     highest threat from this vulnerability is to data confidentiality. (CVE-2020-14330)

  - A flaw was found in the Ansible Engine when using module_args. Tasks executed with check mode (--check-     mode) do not properly neutralize sensitive data exposed in the event data. This flaw allows unauthorized     users to read this data. The highest threat from this vulnerability is to confidentiality.
    (CVE-2020-14332)

  - A flaw was found in the Ansible Engine, in ansible-engine 2.8.x before 2.8.15 and ansible-engine 2.9.x     before 2.9.13, when installing packages using the dnf module. GPG signatures are ignored during     installation even when disable_gpg_check is set to False, which is the default behavior. This flaw leads     to malicious packages being installed on the system and arbitrary code executed via package installation     scripts. The highest threat from this vulnerability is to integrity and system availability.
    (CVE-2020-14365)

  - A security flaw was found in Ansible Engine, all Ansible 2.7.x versions prior to 2.7.17, all Ansible 2.8.x     versions prior to 2.8.11 and all Ansible 2.9.x versions prior to 2.9.7, when managing kubernetes using the     k8s module. Sensitive parameters such as passwords and tokens are passed to kubectl from the command line,     not using an environment variable or an input configuration file. This will disclose passwords and tokens     from process list and no_log directive from debug module would not have any effect making these secrets     being disclosed on stdout and log files. (CVE-2020-1753)

  - A template injection flaw was found in Ansible where a user's controller internal templating operations     may remove the unsafe designation from template data. This issue could allow an attacker to use a     specially crafted file to introduce templating injection when supplying templating data. (CVE-2023-5764)

  - A user changing their email after signing up and verifying it can change it without verification in     profile settings. The configuration option verify_email_enabled will only validate email only on sign     up. (CVE-2023-6152)

  - An information disclosure flaw was found in ansible-core due to a failure to respect the ANSIBLE_NO_LOG     configuration in some scenarios. Information is still included in the output in certain tasks, such as     loop items. Depending on the task, this issue may include sensitive information, such as decrypted secret     values. (CVE-2024-0690)

  - It is possible for a user in a different organization from the owner of a snapshot to bypass authorization     and delete a snapshot by issuing a DELETE request to /api/snapshots/<key> using its view key. This     functionality is intended to only be available to individuals with the permission to write/edit to the     snapshot in question, but due to a bug in the authorization logic, deletion requests issued by an     unprivileged user in a different organization than the snapshot owner are treated as authorized. Grafana     Labs would like to thank Ravid Mazon and Jay Chen of Palo Alto Research for discovering and disclosing     this vulnerability. This issue affects Grafana: from 9.5.0 before 9.5.18, from 10.0.0 before 10.0.13, from     10.1.0 before 10.1.9, from 10.2.0 before 10.2.6, from 10.3.0 before 10.3.5. (CVE-2024-1313)

Note that Nessus has not tested for these issues 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)
