CVE-2020-1733

A race condition flaw was found in Ansible Engine 2.7.17 and prior, 2.8.9 and prior, 2.9.6 and prior 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'.

Updated ansible package fixes security vulnerabilities:

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' (CVE-2020-1733).

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 (CVE-2020-1735).

A flaw was found in the Ansible Engine 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 (CVE-2020-1737).

A flaw was found in Ansible Engine. 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 (CVE-2020-1739).

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 file before recreating it insecurely (CVE-2020-1740).

A flaw was found in the Ansible Engine 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 (CVE-2020-1746).

A security flaw was found in the Ansible Engine when managing Kubernetes using the k8s connection plugin. Sensitive parameters such as passwords and tokens are passed to the kubectl command line instead of using environment variables or an input configuration file, which is safer. This flaw discloses passwords and tokens from the process list, and the no_log directive from the debug module would not be reflected in the underlying command-line tools options, displaying passwords and tokens on stdout and log files (CVE-2020-1753).

A flaw was found in the Ansible Engine. When using ansible_facts as a subkeyof itself, and promoting it to a variable when injecting is enabled, overwriting the ansible_facts after the clean, an attacker could take advantage of this by altering the ansible_facts leading to privilege escalation or code injection. The highest threat from this vulnerability are to data integrity and system availability (CVE-2020-10684).

A flaw was found on Ansible Engine 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 secrets 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 decrypted data remains 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 is sensible (CVE-2020-10685).

Ansible was updated to 2.9.21 to fix lots of bugs and security issues.

Update to version 2.9.20, maintenance release containing numerous bugfixes.

Update to version 2.9.19 with minor changes and a few bug fixes.

Update to version 2.9.18:

• CVE-2021-20228 where default and fallback values for no_log parameters to modules were not previously masked. (bsc#1181935)
• CVE-2021-20178 where several parameters to the snmp_facts module were logged and displayed despite containing sensitive information. (bsc#1180816)
• CVE-2021-20180 where several parameters to the bitbucket_pipeline_variable were logged and displayed despite containing sensitive information. (bsc#1180942)
• CVE-2021-20191 which addresses a number of modules whose parameters were logged and displayed despite containing sensitive information. For the full list of affected modules, refer to the changelog linked below. (bsc#1181119)

Update to version 2.9.17 with minor changes and a few bug fixes.

Update to version 2.9.16 with minor changes and many bug fixes.

update to version 2.9.15 with following breaking change:

• ansible-galaxy login command has been removed

update to version 2.9.14 with many small improvements and bug fixes, most notably:

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)
