CVE-2026-16247

Estado: Pendiente de análisisAlta (7.3)—

In _connect.BRAIN versions prior to 5.06, the application LogPathConfig.exe is executed during setup. During this process, existing permissions on %ProgramData% are deleted and replaced, granting the Windows group Everyone full control instead of restricting access to %ProgramData%\Bizerba\_connect.BRAIN or %ProgramData%\Bizerba\BCT.

Starting with _connect.BRAIN 5.06, the setup no longer executes this tool.
