Cisco Memperingatkan Kelemahan DoS yang Parah dalam Perangkat Lunak Keamanan Jaringan

October 22, 2020 by Winnie the Pooh

Cisco telah mengatasi banyak kerentanan tingkat tinggi di seluruh jajaran produk keamanan jaringannya.

Cacat yang paling parah dapat dimanfaatkan oleh penyerang jarak jauh yang tidak diautentikasi untuk meluncurkan passel serangan berbahaya – dari penolakan layanan (DoS) hingga pemalsuan permintaan lintas situs (cross-site request forgery/CSRF).

Kerentanan ada di perangkat lunak Cisco Firepower Threat Defense (FTD), yang merupakan bagian dari rangkaian produk keamanan jaringan dan manajemen lalu lintas; dan perangkat lunak Adaptive Security Appliance (ASA), sistem operasi untuk keluarga perangkat keamanan jaringan perusahaan ASA.

“Tim Respons Insiden Keamanan Produk Cisco tidak mengetahui pengumuman publik atau penggunaan jahat dari kerentanan yang dijelaskan dalam advisory ini,” menurut Cisco dalam pembaruan yang dirilis pada hari Rabu.

Cacat (CVE-2020-3456) mendapat nilai 8,8 dari 10 pada skala CVSS, dan berasal dari perlindungan CSRF yang tidak mencukupi di antarmuka FCM. Kerentanan ini dapat dieksploitasi untuk mengaktifkan CSRF – yang berarti bahwa ketika penyerang diautentikasi di server, mereka juga memiliki kendali atas klien.
