An information-disclosure flaw was found in the way Heketi before 10.1.0 logs sensitive information. This flaw allows an attacker with local access to the Heketi server to read potentially sensitive information such as gluster-block passwords.

Weakness

Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information.

Extended Description

While logging all information may be helpful during development stages, it is important that logging levels be set appropriately before a product ships so that sensitive user data and system information are not accidentally exposed to potential attackers. Different log files may be produced and stored for:
