SonicWall memperingatkan pelanggan untuk menambal 3 zero-day yang dieksploitasi di alam liar

April 21, 2021 by Winnie the Pooh

Produsen perangkat keras keamanan SonicWall mendesak pelanggan untuk menambal serangkaian tiga kerentanan zero-day yang memengaruhi produk Keamanan Email lokal dan yang dihosting.

“Setidaknya dalam satu kasus yang diketahui, kerentanan ini telah diamati untuk dieksploitasi ‘di alam liar'”, kata SonicWall dalam sebuah advisory keamanan yang mereka terbitkan.

Perusahaan mengatakan itu “keharusan” bahwa organisasi yang menggunakan peralatan perangkat keras Keamanan Email, peralatan virtual, atau instalasi perangkat lunak pada mesin Microsoft Windows Server segera meningkatkan ke versi yang terbaru.

Tiga zero-day yang dilaporkan oleh Josh Fleischer dan Chris DiGiamo dari Mandiant adalah:

  • CVE-2021-20021: Kerentanan Pembuatan Akun Administratif Pra-Otentikasi Keamanan Email yang memungkinkan penyerang membuat akun administratif dengan mengirim permintaan HTTP yang dibuat ke host jarak jauh (pembaruan keamanan dirilis pada 9 April)
  • CVE-2021-20022: Kerentanan Pembuatan File Sewenang-wenang Pasca-Autentikasi Keamanan Email yang memungkinkan penyerang pasca-otentikasi mengunggah file sewenang-wenang ke host jarak jauh (pembaruan keamanan dirilis pada 9 April)
  • CVE-2021-20023: Kerentanan keamanan Email Pasca-Otentikasi Membaca File Sewenang-wenang yang memungkinkan penyerang pasca-otentikasi membaca file sewenang-wenang dari host jarak jauh (pembaruan keamanan dirilis pada 19 April)
