“Zero-day” pada Windows 10 yang baru memberikan hak admin, mendapat tambalan tidak resmi

November 28, 2021 by Søren

Patch tidak resmi gratis telah dirilis untuk melindungi pengguna Windows dari kerentanan zero-day local privilege escalation (LPE) di Layanan Manajemen Perangkat Seluler yang berdampak pada Windows 10, versi 1809 dan yang lebih baru.

Cacat keamanan berada di bawah pengaturan “Akses kantor atau sekolah”, dan melewati patch yang dirilis oleh Microsoft pada bulan Februari untuk mengatasi bug pengungkapan informasi yang dilacak sebagai CVE-2021-24084.

Namun, peneliti keamanan Abdelhamid Naceri (yang juga melaporkan kerentanan awal) menemukan bulan ini bahwa cacat yang tidak sepenuhnya ditambal juga dapat dieksploitasi untuk mendapatkan hak admin setelah mengungkapkan bug yang baru ditemukan pada bulan Juni secara publik.

“Yaitu, seperti yang diajarkan HiveNightmare/SeriousSAM kepada kami, pengungkapan file sewenang-wenang dapat ditingkatkan ke eskalasi hak istimewa lokal jika Anda tahu file mana yang harus diambil dan apa yang harus dilakukan dengannya,” co-founder 0patch Mitja Kolsek menjelaskan hari ini.

“Kami mengkonfirmasi ini dengan menggunakan prosedur yang dijelaskan dalam posting blog ini oleh Raj Chandel sehubungan dengan bug Abdelhamid – dan dapat menjalankan kode sebagai administrator lokal.”

Sementara Microsoft kemungkinan besar juga memperhatikan pengungkapan Naceri pada bulan Juni, perusahaan tersebut belum menambal bug LPE ini, mengekspos sistem Windows 10 dengan pembaruan keamanan November 2021 terbaru untuk serangan.
