This message is not grammatically wrong. This particular usage of the genitive is called Genetivus subiectivus. Your suggestion is adds confusion because it only partly replaces the genitive, while keeping the genitive "verbundener und benachbarter Rechte".

While the message is grammatically correct, it is very badly written and almost incomprehensible. I am not sure how to find out the context where it appears so we can find a more comprehensible wording.
