Microsoft CVE-2019-2102: Bluetooth Low Energy Advisory



Executive Summary Microsoft is aware of an issue that affects the Bluetooth Low Energy (BLE) version of FIDO Security Keys. Due to a misconfiguration in the Bluetooth pairing protocols, it is possible for an attacker who is physically close to a user at the moment he/she uses the security key to communicate with the security key, or communicate with the device to which the key is paired. Google has issued CVE-2019-2102 for this vulnerability. To address this issue, Microsoft has blocked the pairing of these Bluetooth Low Energy (BLE) keys with the pairing misconfiguration. Recommended Actions Microsoft recommends that customers install the June security update for Windows. Customers using the Bluetooth Low Energy (BLE) version of the Titan Security Key by Google should review Android’s June Bulletins and Google’s advisory and take appropriate action. Customers using the Feitian Multipass (Feitian CTAP1/U2F Security Key) should review Feitian's Product Issue Notification website and take appropriate action.
