Bug Cisco Webex memungkinkan penyerang untuk bergabung dalam rapat sebagai pengguna hantu

November 19, 2020 by Winnie the Pooh

Cisco berencana untuk memperbaiki tiga kerentanan di aplikasi konferensi video Webex yang memungkinkan penyerang menyelinap dan bergabung dengan rapat Webex sebagai pengguna bayangan, yang tidak terlihat oleh peserta lain.

Kerentanan tersebut ditemukan awal tahun ini oleh peneliti keamanan dari IBM, yang melakukan peninjauan terhadap alat kerja jarak jauh yang digunakan raksasa perangkat lunak teknologi tersebut secara internal selama pandemi virus corona.

Para peneliti mengatakan tiga bug, jika digabungkan, akan memungkinkan penyerang untuk:
1. Bergabunglah dengan rapat Webex sebagai pengguna bayangan, tidak terlihat oleh orang lain di daftar peserta, tetapi dengan akses penuh ke audio, video, obrolan, dan berbagi layar.
2. Tetap berada dalam rapat Webex sebagai pengguna audio hantu bahkan setelah dikeluarkan darinya.
3. Dapatkan informasi tentang peserta rapat, seperti nama lengkap, alamat email, dan alamat IP. Informasi ini juga dapat diperoleh dari lobi ruang rapat, bahkan sebelum penyerang menerima panggilan.

Peneliti IBM mengatakan bug berada dalam proses “jabat tangan” yang terjadi saat pertemuan Webex baru dibuat. Cisco akan merilis patch hari ini untuk tiga kerentanan Webex yang dilaporkan oleh tim IBM – yaitu CVE-2020-3441, CVE-2020-3471, dan CVE-2020-3419.
