Cisco memperbaiki bug yang memungkinkan eksekusi kode jarak jauh dengan hak akses root

April 8, 2021 by Winnie the Pooh

Cisco telah merilis pembaruan keamanan untuk mengatasi kerentanan pra-otentikasi remote code execution (RCE) yang memengaruhi komponen manajemen jarak jauh SD-WAN vManage Software.

Perusahaan memperbaiki dua kerentanan keamanan tingkat tinggi lainnya dalam fungsi manajemen pengguna (CVE-2021-1137) dan transfer file sistem (CVE-2021-1480) dari produk yang sama yang memungkinkan penyerang untuk meningkatkan hak istimewa.

Eksploitasi yang berhasil dari kedua bug ini dapat memungkinkan pelaku ancaman yang menargetkan mereka untuk mendapatkan hak akses root pada sistem operasi yang mendasarinya.

Cacat keamanan kritis yang dilacak sebagai CVE-2021-1479 menerima skor keparahan 9,8 / 10. Hal ini memungkinkan penyerang jarak jauh yang tidak diautentikasi untuk memicu buffer overflow pada perangkat yang rentan dalam serangan dengan kompleksitas rendah yang tidak memerlukan interaksi pengguna.

Kerentanan memengaruhi Cisco SD-WAN vManage rilis 20.4 dan yang lebih lama. Cisco telah membahasnya dalam pembaruan keamanan 20.4.1, 20.3.3, dan 19.2.4 yang diterbitkan hari ini dan menyarankan pelanggan untuk bermigrasi ke versi yang terbaru sesegera mungkin.
