Eksploitasi dirilis untuk GoAnywhere MFT Zero-day yang Dieksploitasi Secara Aktif

February 8, 2023 by Coffee Bean

Kode eksploit telah dirilis untuk kerentanan zero-day yang dieksploitasi secara aktif yang memengaruhi konsol administrator MFT GoAnywhere yang terpapar Internet.

GoAnywhere MFT adalah alat transfer file berbasis web dan terkelola yang dirancang untuk membantu organisasi mentransfer file secara aman dengan mitra dan menyimpan log audit siapa yang mengakses file bersama.

Pengembangnya adalah Fortra (sebelumnya dikenal sebagai HelpSystems), pakaian di balik alat emulasi ancaman Cobalt Strike yang banyak disalahgunakan.

Fortra mengatakan bahwa “vektor serangan eksploit ini memerlukan akses ke konsol administratif aplikasi, yang dalam banyak kasus hanya dapat diakses dari dalam jaringan perusahaan swasta, melalui VPN, atau dengan alamat IP yang diizinkan (ketika berjalan di cloud lingkungan, seperti Azure atau AWS).”

Namun, pemindaian Shodan menunjukkan bahwa hampir 1.000 instans GoAnywhere terekspos di Internet, meskipun lebih dari 140 berada di port 8000 dan 8001 (yang digunakan oleh konsol admin yang rentan).

Untuk menonaktifkan server lisensi, admin harus mengomentari atau menghapus servlet dan konfigurasi pemetaan servlet untuk Servlet Respons Lisensi di file web.xml untuk menonaktifkan titik akhir yang rentan. Restart diperlukan untuk menerapkan konfigurasi baru.

“Ini termasuk kata sandi dan kunci yang digunakan untuk mengakses sistem eksternal apa pun yang terintegrasi dengan GoAnywhere.

“Pastikan bahwa semua kredensial telah dicabut dari sistem eksternal tersebut dan tinjau log akses relevan yang terkait dengan sistem tersebut. Ini juga termasuk kata sandi dan kunci yang digunakan untuk mengenkripsi file di dalam sistem.”

Fortra juga merekomendasikan untuk mengambil langkah-langkah berikut setelah mitigasi di lingkungan dengan kecurigaan atau bukti adanya serangan:

  • Rotate Master Encryption Key.
  • Reset credentials – keys and/or passwords – for all external trading partners/systems.
  • Review audit logs dan delete semua suspicious admin and/or web user accounts
  • kontak support via the portal https://my.goanywhere.com/, email goanywhere.support@helpsystems.com, atau telephone 402-944-4242 for further assistance.
