Beberapa Pembaruan Keamanan Dirilis untuk Exchange Server – diperbarui 5 Maret 2021

March 6, 2021 by Winnie the Pooh

Hari ini Microsoft merilis beberapa pembaruan keamanan untuk Microsoft Exchange Server untuk mengatasi kerentanan yang telah digunakan dalam serangan bertarget terbatas. Karena sifat kritis dari kerentanan ini, Microsoft menyarankan agar pelanggan segera menerapkan pembaruan ke sistem yang terpengaruh untuk melindungi dari eksploitasi ini dan untuk mencegah penyalahgunaan di masa mendatang di seluruh ekosistem. Kerentanan memengaruhi Microsoft Exchange Server. Exchange Online tidak terpengaruh.

Versi yang terpengaruh adalah:

  • Microsoft Exchange Server 2013
  • Microsoft Exchange Server 2016
  • Server Microsoft Exchange 2019

Kami menyarankan untuk memprioritaskan penginstalan pembaruan pada Server Exchange yang menghadap ke luar. Semua Server Exchange yang terpengaruh pada akhirnya harus diperbarui.

Tidak terkait dengan serangan yang diketahui

  • CVE-2021-26412
  • CVE-2021-26854
  • CVE-2021-27078

Microsoft menyediakan teknik mitigasi alternatif berikut untuk membantu pelanggan Microsoft Exchange yang membutuhkan lebih banyak waktu untuk menambal penerapan mereka dan bersedia melakukan pertukaran risiko dan fungsi layanan.

Mitigasi pada link di atas bukanlah perbaikan jika server Exchange Anda telah disusupi, juga bukan perlindungan penuh terhadap serangan. Kami sangat menyarankan untuk menyelidiki penerapan Exchange Anda menggunakan rekomendasi berburu di sini untuk memastikan bahwa mereka tidak disusupi.
