Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU30585

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-10206

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote authenticated user to gain access to sensitive information.

ansible-playbook -k and ansible cli tools, all versions 2.8.x before 2.8.4, all 2.7.x before 2.7.13 and all 2.6.x before 2.6.19, prompt passwords by expanding them from templates as they could contain special characters. Passwords should be wrapped to prevent templates trigger and exposing them.

2) 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.

4) Inclusion of Sensitive Information in Log Files

EUVDB-ID: #VU33375

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-14858

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

Exploit availability: No

Description

The vulnerability allows a local authenticated user to gain access to sensitive information.

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 displayed if Ansible is run with increased verbosity and present in the module invocation arguments for the task.

Mitigation

Install updates from vendor's website.
