Cleartext Storage of Windows Service Account Password in BRAIN2 Setup Log Files

Overview

A vulnerability has been identified in BRAIN2 versions up to and including version 3.09. Under specific installation conditions, the password of a Windows service account may be written in cleartext to a setup log file. The issue occurs when Microsoft SQL Server access is configured using Integrated Security and the Windows account intended to run the BRAIN2 MainService is specified during execution of the BRAIN2 installation wizard. The setup log file is stored in the temporary directory of the Windows administrator performing the installation. This directory is not accessible to standard Windows users and can generally only be accessed by users with administrative privileges. Successful exploitation could result in the disclosure of credentials belonging to the configured BRAIN2 service account.

Affected

• BRAIN2 >= 0.0 < 3.10

Remediation

This vulnerability has been fixed in BRAIN2 version 3.10.

Customers are strongly advised to upgrade to BRAIN2 version 3.10 or later.

Workarounds

Until an upgrade can be applied, Bizerba recommends implementing the following measures:

·         Delete BRAIN2 installation log files after successful installation.

·         Restrict administrative access to affected systems.

·         Ensure temporary directories containing installation artifacts are adequately protected.

·         Change the password of the configured service account if credential exposure is suspected.

Administrators should review and remove setup log files following the naming convention:
