Bluetooth Classic in Bluetooth Core Specification through 5.3 does not properly conceal device information for Bluetooth transceivers in Non-Discoverable mode. By conducting an efficient over-the-air attack, an attacker can fully extract the permanent, unique Bluetooth MAC identifier, along with device capabilities and identifiers, some of which may contain identifying information about the device owner. This additionally allows the attacker to establish a connection to the target device.
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.
