Pembaruan Keamanan Terbaru Microsoft Memperbaiki 64 Kelemahan Baru, Termasuk Zero-Day

September 15, 2022 by Eevee

Microsoft telah merilis perbaikan keamanan untuk kerentanan zero-day yang memengaruhi semua versi Windows yang didukung yang telah dieksploitasi dalam serangan di dunia nyata.

Bug zero-day, dilacak sebagai CVE-2022-37969, digambarkan sebagai peningkatan cacat hak istimewa di Windows Common Log File System Driver, subsistem yang digunakan untuk data dan pencatatan peristiwa. Bug memungkinkan penyerang untuk mendapatkan tingkat akses tertinggi, yang dikenal sebagai hak istimewa sistem, ke perangkat yang rentan.

Microsoft mengatakan pengguna yang menjalankan Windows 11 dan sebelumnya, dan Windows Server 2008 dan Windows Server 2012, terpengaruh. Windows 7 juga akan menerima patch keamanan, meskipun tidak lagi didukung pada tahun 2020.

Microsoft mengatakan cacat tersebut mengharuskan penyerang sudah memiliki akses ke perangkat yang disusupi, atau kemampuan untuk menjalankan kode pada sistem target.

Microsoft memuji empat kelompok peneliti yang berbeda dari CrowdStrike, DBAPPSecurity, Mandiant, dan Zscaler karena melaporkan kesalahan tersebut, yang mungkin merupakan eksploitasi yang meluas di alam pembohong.

Dhanesh Kizhakkinan, kerentanan bagian utama senior di Mandiant, mengatakan kepada TechCrunch bahwa perusahaan menemukan bug “selama misi pencarian eksploitasi Offensive Task Force proaktif,” menambahkan bahwa eksploitasi mandiri dan bukan dari rantai serangan.

Microsoft tidak membagikan detail tentang serangan yang mengeksploitasi kerentanan ini dan tidak menanggapi permintaan komentar kami.

Perbaikan tersebut masuk kebagian dari rilis bulanan perbaikan keamanan Microsoft Patch Tuesday, yang mencakup total 63 kerentanan di berbagai produk Microsoft, termasuk Microsoft Edge, Office, dan Windows Defender.

Microsoft juga merilis patch untuk cacat zero-day kedua, dilacak sebagai CVE-2022-23960, yang diprediksi sebagai kerentanan cache yang dikenal sebagai “Spectre-BHB” yang memengaruhi Windows 11 untuk sistem berbasis ARM. Spectre-BHB adalah varian dari kerentanan Spectre v2, yang memungkinkan penyerang mencuri data dari memori.
