F5 Memperbaiki Dua Kelemahan Eksekusi Kode Jarak Jauh di BIG-IP, BIG-IQ

November 24, 2022 by Coffee Bean

F5 telah merilis hotfix untuk produk BIG-IP dan BIG-IQ-nya, mengatasi dua kelemahan dengan tingkat keparahan tinggi yang memungkinkan penyerang melakukan eksekusi kode jarak jauh (RCE) yang tidak diautentikasi pada titik akhir yang rentan.

Cacat pertama dilacak sebagai CVE-2022-41622 (CVSS v3 – 8.8) dan merupakan RCE yang tidak diautentikasi melalui pemalsuan lintas situs pada iControl SOAP, yang berdampak pada beberapa versi BIG-IP dan BIG-IQ.

Cacat kedua adalah CVE-2022-41800 (CVSS v3 – 8.7), RCE yang diautentikasi melalui injeksi spesifikasi RPM, yang memengaruhi komponen REST iControl.

Versi BIG-IP yang rentan adalah:

  • 13.1.0 – 13.1.5
  • 14.1.0 – 14.1.5
  • 15.1.0 – 15.1.8
  • 16.1.0 – 16.1.3
  • 17.0.0

untuk BIG-IQ yang terpengaruh adalah

  • 7.1.0
  • 8.0.0 – 8.2.0

Pelanggan yang terpengaruh disarankan untuk meminta hotfix teknis untuk versi produk mereka dari F5 dan menginstalnya secara manual.

Untuk menyelesaikan CVE-2022-41622, admin juga harus menonaktifkan Otentikasi Dasar untuk SOAP iControl setelah menginstal hotfix

Technical details released
Rapid7 menerbitkan laporan terperinci tentang kekurangan yang mengungkapkan rincian teknis dari kerentanan.

“Dengan berhasil mengeksploitasi kerentanan terburuk (CVE-2022-41622), penyerang dapat memperoleh akses root terus-menerus ke antarmuka manajemen perangkat (bahkan jika antarmuka manajemen tidak menghadap ke internet),” jelas laporan oleh Rapid7.

Selain itu, penyerang perlu mengetahui alamat instance BIG-IP yang ditargetkan untuk memberlakukan pemalsuan permintaan lintas situs terhadap admin.

Karena itu, peneliti Rapid7 Ron Bowes percaya bahwa kecil kemungkinan kerentanan akan dieksploitasi secara luas.

Analis telah menerbitkan detail teknis yang ekstensif, termasuk proof of concept exploit untuk CVE-2022-41622, jadi penting untuk mengatasi kerentanan sesegera mungkin.
