Kerentanan hard-coded key di Logix PLC memiliki skor keparahan 10 dari 10

March 3, 2021 by Winnie the Pooh

Perangkat keras yang banyak digunakan untuk mengontrol peralatan di pabrik dan pengaturan industri lainnya dapat dikendalikan dari jarak jauh dengan mengeksploitasi kerentanan yang baru diungkapkan yang memiliki skor tingkat keparahan 10 dari 10.

Kerentanan ditemukan pada pengontrol logika yang dapat diprogram dari Rockwell Automation yang dipasarkan dengan merek Logix.

Pada hari Kamis, Administrasi Keamanan Siber & Infrastruktur AS memperingatkan tentang kerentanan kritis yang dapat memungkinkan peretas untuk terhubung dari jarak jauh ke pengontrol Logix dan dari sana mengubah konfigurasi atau kode aplikasi mereka. Kerentanan tersebut membutuhkan tingkat keterampilan yang rendah untuk dieksploitasi, kata CISA.

Kerentanan, yang dilacak sebagai CVE-2021-22681, adalah hasil dari perangkat lunak Studio 5000 Logix Designer yang memungkinkan peretas untuk mengekstrak kunci enkripsi rahasia. Seorang peretas yang memperoleh kunci tersebut kemudian dapat meniru stasiun kerja teknik dan memanipulasi kode atau konfigurasi PLC yang secara langsung memengaruhi proses manufaktur.

Rockwell tidak mengeluarkan tambalan yang secara langsung mengatasi masalah yang berasal dari kunci yang di-hardcode. Sebaliknya, perusahaan merekomendasikan agar pengguna PLC mengikuti langkah-langkah mitigasi risiko tertentu. Langkah-langkahnya melibatkan menjalankan sakelar mode pengontrol, dan jika itu tidak memungkinkan, mengikuti rekomendasi lain yang khusus untuk setiap model PLC.
