CVE-2020-9824

Restricted network-settings modification by non-privileged users

Published Jun 9, 2020 · Updated Aug 4, 2024

A SIP logic issue in Apple macOS before macOS Catalina 10.15.5 allows local users to modify restricted network settings. Apple has not published the affected SIP routine or the restriction check that mishandles untrusted requests. A non-privileged account is required, and the bounded consequence is unauthorized network-configuration modification rather than broader SIP bypass.
