NSA menemukan kerentanan Exchange Server yang kritis, tambal sekarang!

April 14, 2021 by Winnie the Pooh

Microsoft telah merilis pembaruan keamanan untuk Exchange Server yang menangani empat kerentanan dengan skor tingkat keparahan mulai dari tinggi hingga kritis.

Semua kekurangan mengarah pada eksekusi kode jarak jauh pada mesin yang rentan dan ditemukan serta dilaporkan ke Microsoft oleh Badan Keamanan Nasional AS (NSA). Microsoft juga menemukan beberapa di antaranya secara internal.

Mengingat tingkat keparahan mereka dan pesta peretasan Microsoft Exchange yang dimulai pada awal tahun, organisasi sangat disarankan untuk memprioritaskan pemasangan tambalan terbaru.

Cacat tersebut memengaruhi Exchange Server versi 2013 hingga 2019 dan meskipun tidak ada bukti yang dieksploitasi di alam liar, Microsoft menilai bahwa pelaku ancaman cenderung memanfaatkannya segera setelah mereka membuat eksploitasi.

Empat kerentanan menerima nomor pelacakan (CVE-2021-28480, CVE-2021-28481, CVE-2021-28482, CVE-2021-28483). Yang paling parah dari mereka memiliki skor keparahan kritis 9,8 dari 10 dan dapat dieksploitasi sebelum otentikasi, menurut analis intelijen ancaman senior Microsoft Kevin Beaumont. Kritis lainnya adalah 9/10, dan 8,8 / 10.
