Exploitation Summary
EIP tracks 1 public exploit for CVE-2019-19194. PoCs published by louisabricot.
AI-analyzed exploit summary This repository provides a detailed technical analysis of CVE-2019-19194, a vulnerability in Telink SMP implementations that allows bypassing the Secure Connections pairing procedure in Bluetooth Low Energy (BLE). The writeup includes an overview of BLE protocol stack, pairing procedures, and a theoretical Proof-of-Concept (PoC) script that demonstrates the exploit conceptually.
Description
The Bluetooth Low Energy Secure Manager Protocol (SMP) implementation on Telink Semiconductor BLE SDK versions before November 2019 for TLSR8x5x through 3.4.0, TLSR823x through 1.3.0, and TLSR826x through 3.3 devices installs a zero long term key (LTK) if an out-of-order link-layer encryption request is received during Secure Connections pairing. An attacker in radio range can have arbitrary read/write access to protected GATT service data, cause a device crash, or possibly control a device's function by establishing an encrypted session with the zero LTK.
