Detailsinfo

A vulnerability classified as problematic has been found in Espressif ESP-IDF 4.0/4.1/4.2. Affected is some unknown functionality of the component Bluetooth Low Energy. The manipulation as part of a Packet leads to a assertion vulnerability. CWE is classifying the issue as CWE-617. The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary. This is going to have an impact on availability. CVE summarizes:

The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.0 through 4.2 (for ESP32 devices) returns the wrong number of completed BLE packets and triggers a reachable assertion on the host stack when receiving a packet with an MIC failure. An attacker within radio range can silently trigger the assertion (which disables the target's BLE stack) by sending a crafted sequence of BLE packets.

The weakness was published 08/31/2020. This vulnerability is traded as CVE-2020-13595 since 05/26/2020. Local access is required to approach this attack. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
