Avoid the existence of user accounts with login permission on the target other than administrator access. By default, TwinCAT/BSD has preconfigured user accounts with lower privileges, but none of them have a password, which results in them being denied login access. Avoid running third-party applications on the target that have not been properly audited, regardless of the user they are running as.

- VDE-2024-045Beckhoff: Local authentication bypass in IPC-Diagnostics package included in TwinCAT/BSD operating system2024-08-27csaf · beckhoff_psirtDE
By default, TwinCAT/BSD-based products have a device-specific web interface for web-based management (WBM) enabled, developed by Beckhoff and known as Beckhoff Device Manager UI. It can be accessed remotely or locally. When accessed locally, the authentication mechanism for the web interface can be bypassed by any local user, regardless of their permissions, and they can act with administrative access rights via this mechanism.
