CVE-2022-32819 is a high-severity privilege escalation vulnerability affecting Apple macOS and other Apple operating systems including iOS, iPadOS, watchOS, and tvOS. The vulnerability stems from a logic issue related to improper state management within the operating system, which could allow a malicious app to gain root privileges. Root privileges represent the highest level of access on a Unix-based system such as macOS, enabling an attacker to execute arbitrary code with full system control, bypassing all user-level restrictions. The vulnerability requires local access (AV:L) and low attack complexity (AC:L), but does not require prior privileges (PR:N). However, it does require user interaction (UI:R), meaning the user must run or interact with the malicious app for exploitation to succeed. The vulnerability impacts confidentiality, integrity, and availability (all rated high), allowing an attacker to fully compromise the system. Apple addressed this issue by improving state management in the affected components and released patches in macOS Big Sur 11.6.8, macOS Monterey 12.5, Security Update 2022-005 for Catalina, and corresponding updates for iOS 15.6, iPadOS 15.6, watchOS 8.7, and tvOS 15.6. No known exploits have been reported in the wild as of the publication date, but the high CVSS score of 7.8 and the potential impact make this a critical patch for all users of affected Apple operating systems. The vulnerability is categorized under CWE-269 (Improper Privilege Management), indicating a failure to correctly enforce privilege boundaries within the OS. Given the widespread use of Apple devices in enterprise and consumer environments, this vulnerability represents a significant risk if left unpatched.

For European organizations, this vulnerability poses a serious risk particularly to those with macOS-based infrastructure or employees using Apple devices. Successful exploitation could lead to complete system compromise, data theft, unauthorized access to sensitive information, and disruption of business operations. Organizations in sectors such as finance, healthcare, government, and critical infrastructure, where Apple devices are used, could face regulatory and compliance repercussions if this vulnerability is exploited. The requirement for user interaction means phishing or social engineering could be used to trick users into running malicious apps, increasing the attack surface. Additionally, the ability to gain root privileges could facilitate lateral movement within networks, persistence, and deployment of ransomware or other malware. Given the integration of Apple devices in many European workplaces and the increasing trend of hybrid work environments, the vulnerability could be exploited remotely if attackers gain initial access to user devices. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as exploit code could be developed in the future.

European organizations should prioritize immediate patching of all affected Apple operating systems to the versions specified by Apple (macOS Big Sur 11.6.8, macOS Monterey 12.5, Security Update 2022-005 Catalina, iOS 15.6, iPadOS 15.6, watchOS 8.7, tvOS 15.6). Beyond patching, organizations should implement strict application control policies to prevent installation or execution of unauthorized or untrusted apps, particularly those sourced outside the official Apple App Store. User education campaigns should be conducted to raise awareness about the risks of running unknown applications and the importance of verifying app sources. Endpoint detection and response (EDR) solutions should be tuned to detect suspicious privilege escalation attempts or unusual system behavior indicative of exploitation. Network segmentation and least privilege principles should be enforced to limit the impact of any compromised device. Regular audits of device compliance and software versions can help ensure timely patch deployment. For organizations using Mobile Device Management (MDM) solutions, enforcing mandatory updates and restricting app installation policies can reduce exposure. Finally, incident response plans should be updated to include scenarios involving macOS privilege escalation attacks.
