Inclusion of Sensitive Information in Log Files in ansible (Alpine package)

1) Inclusion of Sensitive Information in Log Files

EUVDB-ID: #VU33354

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-14846

CWE-ID: CWE-532 - Information Exposure Through Log Files

Exploit availability: No

Description

The vulnerability allows a local authenticated user to execute arbitrary code.

Ansible, all ansible_engine-2.x versions and ansible_engine-3.x up to ansible_engine-3.5, was 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.

Mitigation

Install update from vendor's website.

Vulnerable software versions

ansible (Alpine package): 2.6.19-r0
