Hills ComNav version 3002-19 suffers from a weak communication channel. Traffic across the local network for the configuration pages can be viewed by a malicious actor. The size of certain communications packets are predictable. This would allow an attacker to learn the state of the system if they can observe the traffic. This would be possible even if the traffic were encrypted, e.g., using WPA2, as the packet sizes would remain observable. The communication encryption scheme is theoretically sound, but is not strong enough for the level of protection required.
Solution:
The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
The product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor, which exposes security-relevant information about the state of the product, such as whether a particular operation was successful or not.
