CVE-2020-11957 (GCVE-0-2020-11957)
Vulnerability from nvd – Published: 2020-06-09 18:26 – Updated: 2024-08-04 11:42
VLAI
Summary
The Bluetooth Low Energy implementation in Cypress PSoC Creator BLE 4.2 component versions before 3.64 generates a random number (Pairing Random) with significantly less entropy than the specified 128 bits during BLE pairing. This is the case for both authenticated and unauthenticated pairing with both LE Secure Connections as well as LE Legacy Pairing. A predictable or brute-forceable random number allows an attacker (in radio range) to perform a MITM attack during BLE pairing.
