Official description

The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains an incorrect authorization vulnerability in the WebSocket communication used by the SafeController WebMessageBroker.

This allows the attacker to access restricted functions and resources in other branches, including activating boxes outside of the user's authorized branch.
