Microsoft menemukan kerentanan macOS baru “Shrootless” yang dapat melewati System Integrity Protection

October 30, 2021 by Søren

Microsoft telah menemukan kerentanan yang memungkinkan penyerang melewati System Integrity Protection (SIP) di macOS dan melakukan operasi sewenang-wenang pada perangkat.

Peneliti juga menemukan teknik serupa yang memungkinkan penyerang meningkatkan hak istimewa mereka untuk melakukan root pada perangkat yang terpengaruh. Peneliti membagikan temuan ini kepada Apple melalui Coordinated Vulnerability Disclosure (CVD) melalui Microsoft Security Vulnerability Research (MSVR).

Perbaikan untuk kerentanan ini, yang sekarang diidentifikasi sebagai CVE-2021-30892, disertakan dalam pembaruan keamanan yang dirilis oleh Apple pada 26 Oktober 2021.

SIP adalah teknologi keamanan di macOS yang membatasi pengguna root untuk melakukan operasi yang dapat membahayakan integritas sistem.

Peneliti menemukan kerentanan saat menilai proses yang berhak melewati perlindungan SIP. Peneliti menemukan bahwa kerentanannya terletak pada bagaimana paket yang ditandatangani Apple dengan skrip pasca-instal diinstal.

Aktor jahat dapat membuat file yang dibuat khusus yang akan membajak proses instalasi. Setelah melewati batasan SIP, penyerang kemudian dapat menginstal driver kernel berbahaya (rootkit), menimpa file sistem, atau menginstal malware yang persisten dan tidak terdeteksi, dan lain sebagainya.
