Peretas Mengeksploitasi Bug Kritis Cacti untuk Memasang Malware

January 16, 2023 by Flamango

Lebih dari 1.600 contoh alat pemantau perangkat Cacti yang dapat dijangkau melalui internet rentan terhadap masalah keamanan kritis yang sudah mulai dieksploitasi oleh peretas.

Cacti adalah solusi pemantauan manajemen operasional dan kesalahan untuk perangkat jaringan yang juga menyediakan visualisasi grafis. Ada ribuan instans yang diterapkan di seluruh dunia yang diekspos di web.

Penasihat keamanan memperingatkan tentang kerentanan injeksi perintah kritis yang dilacak sebagai CVE-2022-46169 dengan peringkat keparahan 9,8 dari 10, di Cacti yang dapat dieksploitasi tanpa autentikasi.

Selain merilis pembaruan yang memperbaiki kerentanan, pengembang juga memberikan saran untuk mencegah injeksi perintah dan bypass otorisasi.

Awalnya, eksploitasi memasang botnet, seperti malware Mirai. Eksploitasi lain yang diinstal adalah botnet IRC (berbasis PERL) yang membuka shell terbalik pada host dan menginstruksikannya untuk menjalankan pemindaian port. Serangan yang lebih baru hanya memeriksa kerentanan.

Data peneliti Shadowserver menunjukkan upaya eksploitasi untuk kerentanan CVE-2022-46169 di Cacti meningkat minggu lalu dan jumlah total saat ini berada di bawah dua lusin.

Dalam laporan dari platform Censys, perangkat yang terhubung ke Internet, ada 6.427 host Cacti yang terekspos di web. Namun, perusahaan dapat menghitung 1.637 host Cacti yang dapat dijangkau melalui web yang rentan terhadap CVE-2022-46169, banyak di antaranya menjalankan solusi pemantauan versi 1.1.38, yang dirilis pada April 2021.
