VMware mendesak admin untuk segera menambal bug bypass auth kritis

August 3, 2022 by Eevee

VMware telah memperingatkan admin hari ini untuk menambal kelemahan keamanan bypass otentikasi kritis yang memengaruhi pengguna domain lokal di beberapa produk dan memungkinkan penyerang yang tidak diautentikasi untuk mendapatkan hak istimewa admin.

Cacat (CVE-2022-31656) dilaporkan oleh Petrus Viet dari VNG Security, yang menemukan bahwa itu berdampak pada VMware Workspace ONE Access, Identity Manager, dan vRealize Automation.

VMware menilai tingkat keparahan kerentanan keamanan ini sebagai hal yang kritis, dengan skor dasar CVSSv3 9,8/10.

Perusahaan juga menambal beberapa bug keamanan lain yang memungkinkan penyerang mendapatkan eksekusi kode jarak jauh (CVE-2022-31658, CVE-2022-31659, CVE-2022-31665) dan meningkatkan hak istimewa ke ‘root’ (CVE-2022-31660, CVE- 2022-31661, CVE-2022-31664) pada server yang belum ditambal.

Daftar lengkap produk VMware yang terpengaruh oleh kerentanan ini meliputi:

  • VMware Workspace ONE Akses (Akses)
  • VMware Workspace ONE Access Connector (Konektor Akses)
  • Manajer Identitas VMware (vIDM)
  • Konektor Manajer Identitas VMware (Konektor vIDM)
  • VMware vRealize Automation (vRA)
  • VMware Cloud Foundation
  • vRealize Suite Lifecycle Manager

Menurut VMware, tidak ada bukti bahwa kerentanan bypass otentikasi CVE-2022-31656 kritis dieksploitasi dalam serangan.

VMware menyediakan tautan unduhan tambalan dan instruksi instalasi terperinci di situs web basis pengetahuannya.

Perusahaan juga membagikan solusi sementara untuk pelanggan yang tidak dapat segera menambal peralatan mereka terhadap CVE-2022-31656.

Langkah-langkah yang dirinci oleh VMware mengharuskan admin untuk menonaktifkan semua pengguna kecuali satu administrator yang disediakan dan masuk melalui SSH untuk memulai kembali layanan cakrawala-ruang kerja.

Namun, VMware tidak merekomendasikan penggunaan solusi ini dan mengatakan satu-satunya cara untuk mengatasi kelemahan bypass auth CVE-2022-31656 sepenuhnya adalah dengan menambal produk yang rentan.

Perusahaan juga menyediakan dokumen dukungan dengan daftar pertanyaan dan jawaban mengenai bug kritis yang ditambal hari ini.

Pada bulan Mei, VMware menambal kerentanan kritis yang hampir identik, bug bypass otentikasi lain (CVE-2022-22972) yang ditemukan oleh Bruno López dari Innotec Security di Workspace ONE Access, VMware Identity Manager (vIDM), dan vRealize Automation.
