CVE-2020-14330
Improper Output Neutralization for Logs vulnerability in ansible (PyPI)
What is CVE-2020-14330 About?
This Improper Output Neutralization for Logs flaw in Ansible's uri module exposes sensitive data in content and JSON output. Attackers can access logs or task outputs to read keys used in playbooks by other users. This vulnerability is easy to exploit if an attacker has access to Ansible's execution environment or logs.
Affected Software
Technical Details
The vulnerability, categorized as an Improper Output Neutralization for Logs, exists within the Ansible uri module. When this module is used, sensitive data is explicitly exposed within the content and JSON output streams. This means that if the uri module processes sensitive information (e.g., API keys, authentication tokens), these details are not properly neutralized or masked in the resulting output or logs. An attacker who has access to the logs or the standard output of performed Ansible tasks can read these keys, compromising the confidentiality of sensitive data used in playbooks, especially when multiple users share an Ansible execution environment.
What is the Impact of CVE-2020-14330?
Successful exploitation may allow attackers to disclose sensitive data, such as API keys or other credentials, leading to unauthorized access, privilege escalation, or further compromise of the system.
What is the Exploitability of CVE-2020-14330?
Exploitation is low in complexity. An attacker requires access to the system where Ansible logs are stored or where Ansible task output is visible. No specific authentication is directly required to create the vulnerability, but the attacker must be able to read the logs or output. This is typically a local access scenario, though if logs are aggregated and exposed remotely without proper controls, remote exploitation could occur. The principal risk factor is the standard logging behavior and the multi-user environment where sensitive data from one user's playbook execution can be exposed to others through shared logs.
