VAR-201907-1036
Vulnerability from variot - Updated: 2025-01-30 22:28On Fitbit activity-tracker devices, certain addresses never change. According to the popets-2019-0036.pdf document, this leads to "permanent trackability" and "considerable privacy concerns" without a user-accessible anonymization feature. The devices, such as Charge 2, transmit Bluetooth Low Energy (BLE) advertising packets with a TxAdd flag indicating random addresses, but the addresses remain constant. If devices come within BLE range at one or more locations where an adversary has set up passive sniffing, the adversary can determine whether the same device has entered one of these locations. Fitbit Charge 2 Contains an information disclosure vulnerability.Information may be obtained. Fitbit activity-tracker is a smart sports watch made by Fitbit Company in the United States. This vulnerability stems from configuration errors in network systems or products during operation. An unauthorized attacker could exploit the vulnerability to obtain sensitive information of the affected components
