1) Information disclosure

EUVDB-ID: #VU30582

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-2019-10217

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

A flaw was found in ansible 2.8.0 before 2.8.4. Fields managing sensitive data should be set as such by no_log feature. Some of these fields in GCP modules are not set properly. service_account_contents() which is common class for all gcp modules is not setting no_log to True. Any sensitive data managed by that function would be leak as an output when running ansible playbooks.

Mitigation

Install update from vendor's website.
