Affected versions of the Ansible package are vulnerable to Information Disclosure due to improper redaction of sensitive credential fields in verbose log output. The community.general.keycloak_user module logs the credentials[].value parameter in plaintext when Ansible is executed with high verbosity (for example, -vvv), because this field is not marked with the no_log protection that is applied to other password parameters such as auth_password.

A flaw was found in ansible. ansible.cfg is read from the current working directory which can be altered to make it point to a plugin or a module path under the control of an attacker, thus allowing the attacker to execute arbitrary code.

A flaw was found in Ansible Base when using the aws_ssm connection plugin as there is no namespace separation for file transfers. Files are written directly to the root bucket, making possible to have collisions when running multiple ansible processes. This issue affects mainly the service availability. This CVE affects community.aws before 1.2.1 and Ansible-build-data ships this dependency on versions before 2.10.5.

Ansible versions 2.1.4 and 2.2.1 include a fix for CVE-2016-9587: 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.

A flaw was found in Ansible Base when using the aws_ssm connection plugin as garbage collector is not happening after playbook run is completed. Files would remain in the bucket exposing the data. This issue affects directly data confidentiality. This CVE affects community.aws before 1.2.1 and Ansible-build-data ships this dependency on versions before 2.10.5.

A vulnerability was found in Ansible engine and Ansible tower. When a module has an argument_spec with sub parameters marked as no_log, passing an invalid parameter name to the module will cause the task to fail before the no_log options in the sub parameters are processed. As a result, data in the sub parameter fields will not be masked and will be displayed if Ansible is run with increased verbosity and present in the module invocation arguments for the task.

A flaw was found in Ansible 2.7.17 and prior, 2.8.9 and prior, and 2.9.6 and prior when using the Extract-Zip function from the win_unzip module as the extracted file(s) are not checked if they belong to the destination folder. An attacker could take advantage of this flaw by crafting an archive anywhere in the file system, using a path traversal. This issue is fixed in 2.10.

Ansible versions 2.7.17, 2.8.9 and 2.9.6 include a fix for CVE-2020-1739: A flaw was found in Ansible 2.7.16 and prior, 2.8.8 and prior, and 2.9.5 and prior. When a password is set with the argument "password" of svn module, it is used on svn command line, disclosing to other users within the same node. An attacker could take advantage by reading the cmdline file from that particular PID on the procfs.

Ansible 2.2.0 includes a fix for CVE-2016-8628: 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.
https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-8628

Execution of Ansible playbooks on Windows platforms with PowerShell ScriptBlock logging and Module logging enabled can allow for 'become' passwords to appear in EventLogs in plaintext. A local user with administrator privileges on the machine can view these logs and discover the plaintext password.

A flaw was found in the Ansible Engine affecting Ansible Engine versions 2.7.x before 2.7.17 and 2.8.x before 2.8.11 and 2.9.x before 2.9.7 as well as Ansible Tower before and including versions 3.4.5 and 3.5.5 and 3.6.3 when the ldap_attr and ldap_entry community modules are used. The issue discloses the LDAP bind password to stdout or a log file if a playbook task is written using the bind_pw in the parameters field. The highest threat from this vulnerability is data confidentiality.

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.

A flaw was found in the use of insufficiently random values in Ansible. Two random password lookups of the same length generate the equal value as the template caching action for the same file since no re-evaluation happens. The highest threat from this vulnerability would be that all passwords are exposed at once for the file. This flaw affects Ansible Engine versions before 2.9.6.

Ansible versions 2.7.16, 2.8.8 and 2.9.3 include a fix for CVE-2019-14904: A flaw was found in the solaris_zone module from the Ansible Community modules. When setting the name for the zone on the Solaris host, the zone name is checked by listing the process with the 'ps' bare command on the remote machine. An attacker could take advantage of this flaw by crafting the name of the zone and executing arbitrary commands in the remote host. Ansible Engine 2.7.15, 2.8.7, and 2.9.2 as well as previous versions are affected.

Ansible before versions 2.3.1.0 and 2.4.0.0 fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated. See: CVE-2017-7481.

Ansible 2.5.14, 2.6.11 and 2.7.5 include a fix for CVE-2018-16876: Ansible before versions 2.5.14, 2.6.11, 2.7.5 is vulnerable to a information disclosure flaw in vvv+ mode with no_log on that can lead to leakage of sensible data.
https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16876

A flaw was found in Ansible Engine affecting Ansible Engine versions 2.7.x before 2.7.17 and 2.8.x before 2.8.11 and 2.9.x before 2.9.7 as well as Ansible Tower before and including versions 3.4.5 and 3.5.5 and 3.6.3 when using modules which decrypts vault files such as assemble, script, unarchive, win_copy, aws_s3 or copy modules. The temporary directory is created in /tmp leaves the s ts unencrypted. On Operating Systems which /tmp is not a tmpfs but part of the root partition, the directory is only cleared on boot and the decryp emains when the host is switched off. The system will be vulnerable when the system is not running. So decrypted data must be cleared as soon as possible and the data which normally is encrypted ble.

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.

Ansible "User" module leaks any data which is passed on as a parameter to ssh-keygen. This could lean in undesirable situations such as passphrases credentials passed as a parameter for the ssh-keygen executable. Showing those credentials in clear text form for every user which have access just to the process list.

Ansible 2.5.15, 2.6.14 and 2.7.8 include a fix for CVE-2019-3828: Ansible fetch module before versions 2.5.15, 2.6.14, 2.7.8 has a path traversal vulnerability which allows copying and overwriting files outside of the specified destination in the local Ansible controller host by not restricting an absolute path.

Ansible versions 2.7.17, 2.8.11 and 2.9.7 include a fix for CVE-2020-1733: A race condition flaw was found in Ansible Engine when running a playbook with an unprivileged become user. When Ansible needs to run a module with become user, the temporary directory is created in /var/tmp. This directory is created with "umask 77 && mkdir -p <dir>"; this operation does not fail if the directory already exists and is owned by another user. An attacker could take advantage to gain control of the become user as the target directory can be retrieved by iterating '/proc/<pid>/cmdline'.
https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1733

A flaw was found in the Ansible Engine, in ansible-engine affected versions, when installing packages using the dnf module. GPG signatures are ignored during installation even when disable_gpg_check is set to False, the default behaviour. 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.

A flaw was found in the pipe lookup plugin of ansible. Arbitrary commands can be run, when the pipe lookup plugin uses subprocess.Popen() with shell=True, by overwriting ansible facts and the variable is not escaped by quote plugin. An attacker could take advantage and run arbitrary commands by overwriting the ansible facts.

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.

Ansible 2.6.19, 2.7.13 and 2.8.4 include a fix for CVE-2019-10206: Ansible-playbook -k and Ansible cli tools, all versions 2.8.x before 2.8.4, all 2.7.x before 2.7.13 and all 2.6.x before 2.6.19, prompt passwords by expanding them from templates as they could contain special characters. Passwords should be wrapped to prevent templates trigger and exposing them.

Ansible 2.6.18, 2.7.12 and 2.8.2 include a fix for CVE-2019-10156: A flaw was discovered in the way Ansible templating was implemented in versions before 2.6.18, 2.7.12 and 2.8.2, causing the possibility of information disclosure through unexpected variable substitution. By taking advantage of unintended variable substitution the content of any variable may be disclosed.
https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10156

In Ansible, all Ansible Engine versions up to ansible-engine 2.8.5, ansible-engine 2.7.13, ansible-engine 2.6.19, were logging at the DEBUG level which lead to a disclosure of credentials if a plugin used a library that logged credentials at the DEBUG level. This flaw does not affect Ansible modules, as those are executed in a separate process.

Ansible versions 2.7.17, 2.8.9 and 2.9.6 include a fix for CVE-2020-1735: A flaw was found in the Ansible Engine when the fetch module is used.
