Microsoft has shared details of a now-patched flaw in Apple macOS that could be abused by threat actors with root access to bypass security enforcements and perform arbitrary actions on affected devices.

Specifically, the flaw – dubbed Migraine and tracked as CVE-2023-32369 – could be abused to get around a key security measure called System Integrity Protection (SIP), or “rootless,” which limits the actions the root user can perform on protected files and folders.

“The most straight-forward implication of a SIP bypass is that […] an attacker can create files that are protected by SIP and therefore undeletable by ordinary means,” Microsoft researchers Jonathan Bar Or, Michael Pearse, and Anurag Bohra said.

Even worse, it could be exploited to gain arbitrary kernel code execution and even access sensitive data by replacing databases that manage Transparency, Consent, and Control (TCC) policies.
