An Improper Authentication issue was discovered in Siemens SIMATIC CP 44x-1 RNA, all versions prior to 1.4.1. An unauthenticated remote attacker may be able to perform administrative actions on the Communication Process (CP) of the RNA series module, if network access to Port 102/TCP is available and the configuration file for the CP is stored on the RNAs CPU.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
