Cisco mengungkapkan zero-day VPN AnyConnect

November 5, 2020 by Winnie the Pooh

Cisco telah mengungkapkan kerentanan zero-day dalam perangkat lunak Cisco AnyConnect Secure Mobility Client dengan kode eksploitasi proof-of-concept yang tersedia untuk umum.

Meskipun pembaruan keamanan belum tersedia untuk kerentanan eksekusi kode arbitrary ini, Cisco sedang berupaya mengatasi zero-day, dengan perbaikan yang akan datang di rilis klien AnyConnect mendatang.

Namun, kelemahan keamanan Cisco AnyConnect Secure Mobility Client belum dieksploitasi di dunia nyata menurut Cisco Product Security Incident Response Team (PSIRT).

Kerentanan dengan tingkat keparahan tinggi yang dilacak sebagai CVE-2020-3556 ada di saluran komunikasi antarproses (IPC) dari Cisco AnyConnect Client dan dapat memungkinkan penyerang lokal dan terotentikasi untuk mengeksekusi skrip berbahaya melalui pengguna yang ditargetkan.

Ini memengaruhi semua versi klien AnyConnect untuk Windows, Linux, dan macOS dengan konfigurasi yang rentan – klien iOS dan Android seluler tidak terpengaruh oleh kerentanan ini.

Meskipun tidak ada solusi yang tersedia untuk mengatasi CVE-2020-3556, ini dapat dikurangi dengan menonaktifkan fitur Pembaruan Otomatis.

Permukaan serangan juga dapat dikurangi secara drastis dengan mematikan pengaturan konfigurasi Enable Scripting pada perangkat yang mengaktifkannya.
