Ansible leaks sensitive information to logs when told not to

A vulnerability was found in Ansible engine 2.x up to 2.8 and Ansible tower 3.x up to 3.5. 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 …

Ansible Code Injection Vulnerability

The safe_eval function in Ansible before 1.6.4 does not properly restrict the code subset, which allows remote attackers to execute arbitrary code via crafted instructions. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-4657.

Ansible discloses credential information

Ansible before 1.5.5 constructs filenames containing user and password fields on the basis of deb lines in sources.list, which might allow local users to obtain sensitive credential information in opportunistic circumstances by leveraging existence of a file that uses the deb http://user:pass@server:port/ format.

Ansible Arbitrary Code Execution

Multiple argument injection vulnerabilities in Ansible before 1.6.7 allow remote attackers to execute arbitrary code by leveraging access to an Ansible managed host and providing a crafted fact, as demonstrated by a fact with (1) a trailing " src=" clause, (2) a trailing " temp=" clause, or (3) a trailing " validate=" clause accompanied by a shell command.

Ansible Arbitrary Code Execution

Ansible before 1.6.7 does not prevent inventory data with "{{" and "lookup" substrings, and does not prevent remote data with "{{" substrings, which allows remote attackers to execute arbitrary code via (1) crafted lookup('pipe') calls or (2) crafted Jinja2 data.

Insertion of Sensitive Information into Log File

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.

OS Command Injection in ansible

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.

Incorrect Permission Assignment for Critical Resource in Ansible

A flaw was found in Ansible Engine when a file is moved using atomic_move primitive as the file mode cannot be specified. This sets the destination files world-readable if the destination file does not exist and if the file exists, the file could be changed to have less restrictive permissions before the move. This could lead to the disclosure of sensitive data. All versions in 2.7.x, 2.8.x and 2.9.x branches …

Improper Neutralization of Special Elements used in a Command ('Command Injection')

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 …

Insufficiently random values in Ansible

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.

Time-of-check Time-of-use (TOCTOU) Race Condition

A flaw was found in Ansible if an ansible user sets ANSIBLE_ASYNC_DIR to a subdirectory of a world writable directory. When this occurs, there is a race condition on the managed machine. A malicious, non-privileged account on the remote machine can exploit the race condition to access the async result data. This flaw affects Ansible Tower and Ansible Automation Platform

Exposure of Resource to Wrong Sphere

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.

Path Traversal

An archive traversal flaw was found in all ansible-engine, when running ansible-galaxy collection install. When extracting a collection .tar.gz file, the directory is created without sanitizing the filename. An attacker could take advantage to overwrite any file within the system.

Externally Controlled Reference to a Resource in Another Sphere

A vulnerability was found in Ansible Engine where in Ansible's nxos_file_copy module can be used to copy files to a flash or bootflash on NXOS devices. Malicious code could craft the filename parameter to perform OS command injections. This could result in a loss of confidentiality of the system among other issues.

Code Injection

When using ansible_facts as a subkey of itself and promoting it to a variable when inject is enabled, overwriting the ansible_facts after the clean. An attacker could take advantage of this by altering the ansible_facts, such as ansible_hosts, users and any other key data which would lead into privilege escalation or code injection.

Path Traversal

A flaw was found in the Ansible Engine when the fetch module is used. An attacker could intercept the module, inject a new path, and then choose a new destination path on the controller node.

Information Exposure

A flaw was found in Ansible Engine when using Ansible Vault for editing encrypted files. When a user executes ansible-vault edit, another user on the same computer can read the old and new secret, as it is created in a temporary file with mkstemp and the returned file descriptor is closed and the method write_data is called to write the existing secret in the file. This method will delete the …

Inclusion of Sensitive Information in Log Files

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.

Argument Injection or Modification

A flaw was found in Ansible Engine when the module package or service is used and the parameter use is not specified. If a previous task is executed with a malicious user, the module sent can be selected by the attacker using the ansible facts file.

Information Exposure

Exposure of Resource to Wrong Sphere

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 && 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 …

Path Traversal

A flaw was found in Ansible 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.

Improper Output Neutralization for Logs

Ansible, versions 2.9.x before 2.9.1, 2.8.x before 2.8.7 and Ansible versions 2.7.x before 2.7.15, is not respecting the flag no_log set it to True when Sumologic and Splunk callback plugins are used send tasks results events to collectors. This would discloses and collects any sensitive data.

Security fix for vault

The vault subsystem in Ansible does not set the umask before creation or modification of a vault file, which allows local users to obtain sensitive key information by reading a file.

2019

Information Exposure

Fields managing sensitive data should be set as such by no_log feature. Some of these fields in GCP modules are not set properly. service_account_contents() which is common class for all gcp modules is not setting no_log to True. Any sensitive data managed by that function would be leaked as an output when running ansible playbooks.

Improper Input Validation

ansible-playbook -k and ansible cli tools prompt passwords by expanding them from templates as they could contain special characters. Passwords should be wrapped to prevent templates trigger and exposing them.

Information Exposure

A flaw was discovered in the way Ansible templating was implemented 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.

Path Traversal

Ansible fetch module has a path traversal vulnerability which allows copying and overwriting files outside the specified destination in the local ansible controller host, by not restricting an absolute path.

2018

Information Exposure

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.

Information Exposure

The 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.

Improper Link Resolution Before File Access

The create_script function in the lxc_container module in Ansible before 1.9.6-1 and 2.x before 2.0.2.0 allows local users to write to arbitrary files or gain privileges via a symlink attack on the archived container in the archive_path directory, or the lxc-attach-script.err files in the temporary directory.

Improper Input Validation

An input validation vulnerability was found in Ansible's mysql_user module, 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.

Improper Input Validation

Ansible 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.

Untrusted Search Path

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.

Improper Control of Generation of Code

An exploitable vulnerability exists in the yaml loading functionality of ansible-vault before 1.0.5. A specially crafted vault can execute arbitrary python commands resulting in command execution. An attacker can insert python into the vault to trigger this vulnerability.

Inclusion of Sensitive Information in Log Files

Ansible does not honor the no_log task flag for failed tasks. When the no_log flag has been used to protect sensitive data passed to a task from being logged, and that task does not run successfully, Ansible will expose sensitive data in log files and on the terminal of the user running Ansible.

Improper Input Validation

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. The attacker can run arbitrary code as a result.

Improper Input Validation

Ansible has an input validation vulnerability in the 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.

Improper Input Validation

Ansible 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.

Improper Authentication

transport.py in the SSH server implementation of Paramiko does not properly check whether authentication is completed before processing other requests, as demonstrated by channel-open. A customized SSH client can simply skip the authentication step.

2017

Possible escape from confined environment

Improprer symlink handling in zone, jail, and chroot connection plugins could lead to escape from confined environment. File copying is not performed by code that is operating within the restricted environment (chroot, jail, or zone).

2015

Improper TLS Certificate Validation

Ansible fails to adequately validate HTTPS certificates when using the get_url and uri modules, and when using the url and etcd lookup plugins. This allows for man-in-the-middle attacks on those connections.
