Bug LEGO BrickLink memungkinkan peretas membajak akun, merusak server

December 18, 2022 by Søren

Analis keamanan telah menemukan dua kerentanan keamanan API di BrickLink.com, pasar barang bekas dan vintage resmi LEGO Group untuk batu bata LEGO.

BrickLink adalah komunitas online penggemar LEGO terbesar di dunia, dengan lebih dari satu juta anggota terdaftar.

Dua masalah keamanan API yang ditemukan oleh Salt Security dapat memungkinkan penyerang mengambil alih akun anggota, mengakses dan mencuri informasi identitas pribadi (PII) yang disimpan di platform, atau bahkan mendapatkan akses ke data produksi internal dan membahayakan server internal.

Analis Salt Security menemukan kerentanan saat bereksperimen dengan bidang masukan pengguna di situs web BrickLink.

Yang pertama adalah cacat cross-site scripting (XSS) di kotak dialog “Temukan Nama Pengguna” di bagian pencarian kupon, yang memungkinkan penyerang menyuntikkan dan mengeksekusi kode pada mesin target menggunakan tautan yang dibuat khusus.

Menggunakan ID Sesi target yang diekspos di halaman berbeda, penyerang dapat memanfaatkan kelemahan XSS untuk membajak sesi dan mengambil alih akun target.

Mengakses akun berarti membuka semua data yang disimpan di platform, termasuk detail pribadi, alamat email, alamat pengiriman, riwayat pesanan, kupon, umpan balik yang diterima, item yang diinginkan, dan riwayat pesan.

Cacat kedua terletak pada halaman “Unggah ke Daftar Dicari”, di mana pengguna dapat mengunggah daftar XML yang berisi bagian LEGO yang ingin mereka temukan dan beli.

Dengan mengeksploitasi kelemahan dalam mekanisme penguraian titik akhir, analis Salt Security meluncurkan serangan injeksi Entitas Eksternal XML (XXE) yang berhasil, menambahkan referensi ke entitas eksternal pada file mereka.

Serangan XXE memungkinkan mereka untuk membaca file di server web dan mengeksekusi serangan pemalsuan permintaan sisi server (SSRF), yang dapat menyebabkan pengusiran token AWS EC2 untuk server.
