September 3, 2021 by Winnie the Pooh

Kerentanan secara kolektif disebut sebagai BrakTooth mempengaruhi Bluetooth stacks yang diimplementasikan pada sirkuit system-on-a-chip (SoC) dari lebih dari selusin vendor.

Serangkaian masalah berdampak pada berbagai perangkat, mulai dari elektronik konsumen hingga peralatan industri. Risiko terkait berkisar dari penolakan layanan, kondisi kebuntuan perangkat hingga eksekusi kode arbitrer.

Para peneliti dari Singapore University of Technology and Design telah menerbitkan rincian tentang BrakTooth – keluarga baru kerentanan keamanan dalam Bluetooth stacks komersial.

Mereka menilai 13 perangkat Bluetooth dari hampir selusin vendor SoC termasuk Intel, Qualcomm, Texas Instruments, dan Cypress.

Menggali lebih dalam, para peneliti menemukan bahwa lebih dari 1.400 daftar produk dipengaruhi oleh BrakTooth, dan daftar tersebut termasuk tetapi tidak terbatas pada jenis perangkat: Smartphone, Sistem infotainment, Sistem laptop dan desktop, Perangkat audio (speaker, headphone), Sistem hiburan rumah, Keyboard, mainan, Peralatan industri (misalnya pengontrol logika yang dapat diprogram – PLC)

Mempertimbangkan berbagai produk yang terpengaruh, kemungkinan besar bahwa BrakTooth memengaruhi miliaran perangkat.

Para peneliti mengatakan bahwa risiko yang terkait dengan serangkaian kelemahan keamanan BrakTooth berkisar dari penolakan layanan (DoS) dengan merusak firmware perangkat, atau kondisi kebuntuan di mana komunikasi Bluetooth tidak lagi memungkinkan, hingga kode arbitrer.

Seseorang yang melakukan serangan BrakTooth akan memerlukan kit pengembangan ESP32, firmware Link Manager Protocol (LMP) kustom, dan komputer untuk menjalankan alat proof-of-concept (PoC).

Dari 16 kerentanan BrakTooth, salah satunya dilacak sebagai CVE-2021-28139 menghadirkan risiko yang lebih tinggi daripada yang lain karena memungkinkan eksekusi kode arbitrer.
