EUVDB-ID: #VU48977

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-2020-8564

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

Exploit availability: No

Description

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

The vulnerability exists due to software stores sensitive information into log files. In Kubernetes clusters using a logging level of at least 4, processing a malformed docker config file will result in the contents of the docker config file being leaked, which can include pull secrets or other registry credentials. A local user can read the log files and gain access to sensitive data.

Mitigation

Install updates from vendor's website.
