Cisco Mengeluarkan Patch Untuk 2 Kerentanan IOS XR Tingkat Tinggi di Bawah Serangan Aktif

October 1, 2020 by Winnie the Pooh

Cisco telah merilis tambalan keamanan untuk dua kerentanan tingkat tinggi yang mempengaruhi perangkat lunak IOS XR-nya yang ditemukan sedang dieksploitasi sebulan lalu.

Dilacak sebagai CVE-2020-3566 dan CVE-2020-3569, detail untuk kerentanan DoS zero-day yang tidak diautentikasi dipublikasikan oleh Cisco akhir bulan lalu ketika perusahaan menemukan peretas secara aktif mengeksploitasi Perangkat Lunak Cisco IOS XR yang diinstal pada berbagai router tingkat operator dan pusat data Cisco.

“Kerentanan ini memengaruhi semua perangkat Cisco yang menjalankan rilis apa pun dari Perangkat Lunak Cisco IOS XR jika antarmuka aktif dikonfigurasi di bawah perutean multicast dan menerima lalu lintas DVMRP,” kata Cisco dalam sebuah advisory.

Eksploitasi yang berhasil dapat memungkinkan peretas jarak jauh yang tidak diautentikasi untuk mengirim paket IGMP yang dibuat khusus ke perangkat yang terpengaruh untuk segera merusak proses IGMP atau menghabiskan memori proses dan akhirnya crash.

Pelanggan Cisco sangat disarankan untuk memastikan bahwa mereka menjalankan rilis Perangkat Lunak Cisco IOS XR terbaru sebelum 6.6.3 dan Perangkat Lunak Cisco IOS XR rilis 6.6.3 dan yang lebih baru.
