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

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.
