Camera credential compromise via brute-forceable service credentials

Weak credentials in Reolink Home Hub before 3.3.0.456_26031911 allow remote attackers on the local network to compromise camera credentials. The netclient and factory services rely on credentials weak enough for brute-force recovery from intercepted traffic. The attack requires access to the same local network and interception of hub-to-camera traffic; the documented consequence is exposure of associated-camera credentials.
