New “Migraine” Flaw Enables Attackers to Bypass MacOS Security

A new vulnerability has been found out in macOS that enables attackers with root entry to bypass System Integrity Defense (SIP) and carry out arbitrary operations on influenced gadgets.

Discovered by Microsoft and dubbed “Migraine,” the flaw was disclosed to Apple by Coordinated Vulnerability Disclosure (CVD) by way of Microsoft Security Vulnerability Research (MSVR).

SIP is a security technology executed in macOS that stops a root person from compromising process integrity. Also recognized as “rootless,” SIP was released by Apple in macOS Yosemite as a security evaluate. It restricts root person obtain to delicate procedure data files and directories.

Technically speaking, SIP cannot be disabled on a live system and rather needs physical accessibility to the unit by the recovery OS. A SIP bypass lets an attacker to override SIP-secured directories and files.

Bypassing SIP could for that reason direct to the installation of rootkits, the generation of persistent malware and an expanded attack surface area for additional exploits.

Microsoft defined that the procedure utilized to exploit the vulnerability is identical to the just one discovered in the Shrootless vulnerability (tracked CVE-2021-30892) revealed in 2021.

“By concentrating on procedure procedures that are signed by Apple and have the com.apple.rootless.put in.heritable entitlement, we located two little one procedures that could be tampered with to gain arbitrary code execution in a security context that bypasses SIP checks,” reads a Microsoft advisory revealed Tuesday.

The tech large verified Apple has launched security updates on May possibly 18 2023, addressing the issue recognized as CVE-2023-32369.

“A logic issue was resolved with enhanced condition administration,” Apple wrote in its security bulletin, crediting Microsoft scientists Jonathan Bar Or, Anurag Bohra and Michael Pearse for the discovery.
