Netgear memperbaiki bug keamanan yang parah di lebih dari selusin sakelar pintar

September 10, 2021 by Winnie the Pooh

Netgear telah merilis pembaruan firmware untuk lebih dari selusin sakelar pintar yang digunakan pada jaringan perusahaan untuk mengatasi kerentanan dengan tingkat keparahan tinggi.

Perusahaan memperbaiki tiga kelemahan keamanan yang memengaruhi 20 produk Netgear, sebagian besar smart switch. Detail teknis dan kode eksploitasi proof-of-concept (PoC) untuk dua bug tersedia untuk umum.

Sebuah advisory dari Netgear pada hari Jumat menginformasikan bahwa versi firmware baru tersedia untuk beberapa sakelarnya yang dipengaruhi oleh tiga kerentanan keamanan yang menerima skor keparahan antara 7,4 dan 8,8 pada skala 10.

Netgear mengidentifikasi bug sebagai PSV-2021-0140, PSV-2021-0144, PSV-2021-0145, karena nomor pelacakan belum ditetapkan. Banyak produk yang terpengaruh adalah sakelar pintar, beberapa di antaranya dengan kemampuan manajemen cloud yang memungkinkan konfigurasi dan pemantauannya melalui web.

Advisory Netgear tidak menulis detail teknis apa pun tentang bug tersebut tetapi “sangat menyarankan Anda mengunduh firmware terbaru sesegera mungkin.”

Peneliti keamanan Gynvael Coldwind, yang menemukan dan melaporkan kerentanan, menjelaskan dua masalah dan memberikan kode eksploitasi demo untuk mereka.

Coldwind mengatakan dalam laporan keamanannya bahwa salah satu kelemahan, yang oleh peneliti disebut Demon’s Cries, adalah bypass otentikasi yang dapat, dalam kondisi tertentu, memungkinkan penyerang untuk mengendalikan perangkat yang rentan.
