Windows zero-day baru dengan eksploitasi publik memungkinkan Anda menjadi admin

November 23, 2021 by Winnie the Pooh

Seorang peneliti keamanan telah secara terbuka mengungkapkan eksploitasi untuk kerentanan zero-day elevasi hak istimewa lokal Windows baru yang memberikan hak istimewa admin di Windows 10, Windows 11, dan Windows Server.

BleepingComputer telah menguji eksploit dan menggunakannya untuk membuka ke command prompt dengan hak istimewa SISTEM dari akun yang hanya memiliki hak ‘Standar’ tingkat rendah.

Dengan menggunakan kerentanan ini, pelaku ancaman dengan akses terbatas ke perangkat yang disusupi dapat dengan mudah meningkatkan hak istimewa mereka untuk membantu menyebar secara lateral di dalam jaringan.

Kerentanan memengaruhi semua versi Windows yang didukung, termasuk Windows 10, Windows 11, dan Windows Server 2022.

Sebagai bagian dari Patch Selasa November 2021, Microsoft memperbaiki kerentanan ‘Windows Installer Elevation of Privilege Vulnerability’ yang dilacak sebagai CVE-2021-41379.

Kerentanan ini ditemukan oleh peneliti keamanan Abdelhamid Naceri, yang menemukan bypass ke patch dan kerentanan elevasi hak istimewa zero-day baru yang lebih kuat setelah memeriksa perbaikan dari Microsoft.

Kemarin, Naceri menerbitkan exploit proof-of-concept yang berfungsi untuk zero-day baru di GitHub, menjelaskan bahwa itu berfungsi pada semua versi Windows yang didukung.

Naceri juga menjelaskan bahwa meskipun user dapat mengonfigurasi kebijakan grup untuk mencegah pengguna ‘Standar’ melakukan operasi MSI installer, zero-day-nya melewati kebijakan ini dan akan tetap berfungsi.
