Improper Input Validation

ansible-core is an a radically simple IT automation system. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible makes complex changes like zero-downtime rolling updates with load balancers easy.

Affected versions of this package are vulnerable to Improper Input Validation through the use of the hostvars object. Attackers can bypass unsafe content protections and execute templated content, leading to arbitrary code execution. This is only exploitable if attackers can modify the content returned to a play that utilizes hostvars to reference unsafe content

How to fix Improper Input Validation?

Upgrade ansible-core to version 2.16.9, 2.17.2 or higher.

[,2.16.9)[2.17.0b1,2.17.2)

Incorrect Authorization

Affected versions of this package are vulnerable to Incorrect Authorization through the user module. An attacker can modify or replace file contents and take ownership of files on any system path by exploiting directory traversal permissions.

Note:

This is only exploitable if someone with root privileges uses the user module with the generate_ssh_key option (disabled by default) and targets an unprivileged user. The unprivileged user needs to have traversal permissions on the directory containing the exploited target file.

How to fix Incorrect Authorization?

Upgrade ansible-core to version 2.14.18rc1, 2.15.13rc1, 2.16.13rc1, 2.17.6rc1, 2.18.0rc2 or higher.

Symlink Attack

Affected versions of this package are vulnerable to Symlink Attack via the ansible-galaxy function. When installing a maliciously created Ansible role using ansible-galaxy role install, arbitrary files the user has access to can be overwritten. The malicious role must contain a symlink with an absolute path to the target file, followed by a file of the same name (as the symlink) with the contents to write to the target.

How to fix Symlink Attack?
