Beckhoff: Improper neutralization of input in IPC-Diagnostics-www package included in TwinCAT/BSD operating system
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 user can bypass input validation by entering specially crafted inputs into the user interface for certain pages, which then allows local commands to be executed with administrative privileges.

- Mitigation
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.
- Behoben
Please update to a recent version of the affected product.
