Transfer MOVEit Baru zero-day yang Dieksploitasi Massal Serangan Pencurian Data

June 2, 2023 by Coffee Bean

Peretas secara aktif mengeksploitasi kerentanan zero-day dalam perangkat lunak transfer file MOVEit Transfer untuk mencuri data dari organisasi.

MOVEit Transfer adalah solusi transfer file terkelola (MFT) yang dikembangkan oleh Ipswitch, anak perusahaan Progress Software Corporation yang berbasis di AS, yang memungkinkan perusahaan mentransfer file dengan aman antara mitra bisnis dan pelanggan menggunakan unggahan berbasis SFTP, SCP, dan HTTP.

Detail serangan
Perusahaan keamanan siber Rapid7 mengatakan bahwa kelemahan Transfer MOVEit adalah kerentanan injeksi SQL yang mengarah ke eksekusi kode jarak jauh dan saat ini tidak memiliki CVE yang ditugaskan padanya.

Rapid7 mengatakan ada 2.500 server Transfer MOVEit yang terbuka, dengan mayoritas berlokasi di AS, dan webshell yang sama ditemukan di semua perangkat yang dieksploitasi.

Webshell ini bernama ‘human2.asp’ [VirusTotal] dan terletak di folder HTML publik c:\MOVEit Transfer\wwwroot\.

“Kode webshell pertama-tama akan menentukan apakah permintaan masuk berisi header bernama X-siLock-Comment, dan akan mengembalikan kesalahan 404 “Tidak Ditemukan” jika header tidak diisi dengan nilai seperti kata sandi tertentu,’ jelas Rapid7.

Webshell diintasl oleh exploit di MOVEit Transfer Servers.

Dari analisis oleh BleepingComputer, ketika webshell diakses dan kata sandi yang benar diberikan, skrip akan menjalankan berbagai perintah berdasarkan nilai ‘X-siLock-Step1’, ‘X-siLock-Step1’, dan ‘X-siLock-Step1’, dan ‘X-siLock-Step1’, ‘X-siLock-Step1’, dan ‘X-siLock-Step1’ Header permintaan Step3.

Perintah ini memungkinkan aktor ancaman mengunduh berbagai informasi dari server MySQL MOVEit Transfer dan melakukan berbagai tindakan, termasuk:

  • Ambil daftar file yang disimpan, nama pengguna yang mengunggah file, dan jalur file mereka.
  • Masukkan dan hapus pengguna MOVEit Transfer acak baru bernama dengan nama login ‘Health Check Service’ dan buat sesi MySQL baru.
  • Dapatkan informasi tentang akun Azure Blob Storage yang dikonfigurasi, termasuk pengaturan AzureBlobStorageAccount, AzureBlobKey, dan AzureBlobContainer, seperti yang dijelaskan dalam artikel bantuan Kemajuan ini.

Saat ini, para pelaku ancaman belum mulai memeras korban, sehingga tidak jelas siapa dalang di balik penyerangan tersebut.

Namun, eksploitasi tersebut sangat mirip dengan eksploitasi massal pada Januari 2023 terhadap zero-day MFT GoAnywhere dan eksploitasi zero-day server Accellion FTA pada Desember 2020.
