|---|---|---|---|
| 2021-05-24 | CVE-2020-26556 | Improper Restriction of Excessive Authentication Attempts vulnerability in Bluetooth Core Specification and Mesh Profile Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device, able to conduct a successful brute-force attack on an insufficiently random AuthValue before the provisioning procedure times out, to complete authentication by leveraging Malleable Commitment. | 7.5 |
| 2021-05-24 | CVE-2020-26557 | Improper Authentication vulnerability in Bluetooth Mesh Profile 1.0.0/1.0.1 Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device (without possession of the AuthValue used in the provisioning protocol) to determine the AuthValue via a brute-force attack (unless the AuthValue is sufficiently random and changed each time). | 7.5 |
| 2021-05-24 | CVE-2020-26559 | Incorrect Authorization vulnerability in Bluetooth Mesh Profile 1.0.0/1.0.1 Bluetooth Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device (participating in the provisioning protocol) to identify the AuthValue used given the Provisioner’s public key, and the confirmation number and nonce provided by the provisioning device. | 8.8 |
| 2021-05-24 | CVE-2020-26560 | Incorrect Authorization vulnerability in Bluetooth Mesh Profile 1.0.0/1.0.1 Bluetooth Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device, reflecting the authentication evidence from a Provisioner, to complete authentication without possessing the AuthValue, and potentially acquire a NetKey and AppKey. | 8.1 |
