CVE-2022-32881 is a logic vulnerability in Apple macOS and related operating systems (including iOS, watchOS, and tvOS) that allows an application to potentially modify protected parts of the file system. The issue arises from insufficient restrictions in the system's logic that govern file system access controls. Specifically, an app with limited privileges may exploit this flaw to alter files or directories that are normally protected by the operating system's security mechanisms. This could lead to unauthorized changes in critical system files or configurations. The vulnerability affects multiple Apple OS versions, including macOS Big Sur 11.7, macOS Monterey 12.6, macOS Ventura 13, iOS 16, watchOS 9, and tvOS 16. Apple addressed this issue by implementing improved restrictions to prevent unauthorized modifications. The CVSS v3.1 base score is 5.5 (medium severity), with the vector indicating that the attack requires local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:R). The impact is high on integrity (I:H) but no impact on confidentiality or availability. There are no known exploits in the wild reported to date. The vulnerability is significant because it allows an unprivileged app to escalate its ability to modify protected file system areas, potentially undermining system integrity and security policies.

For European organizations, this vulnerability poses a risk primarily to environments where macOS and related Apple operating systems are widely used, such as in creative industries, software development, and certain enterprise sectors. If exploited, malicious or compromised applications could alter critical system files, potentially leading to persistent malware installation, tampering with security configurations, or disruption of system operations. This could undermine trust in device integrity, lead to data corruption, or facilitate further attacks. Although exploitation requires local access and user interaction, insider threats or social engineering attacks could leverage this vulnerability. The impact on confidentiality is minimal, but the integrity of systems could be significantly compromised, affecting compliance with data protection regulations like GDPR if system integrity is a component of security controls. Organizations relying on Apple ecosystems should consider this vulnerability in their risk assessments and incident response planning.

1. Ensure all Apple devices are updated to the latest patched versions of macOS (Big Sur 11.7, Monterey 12.6, Ventura 13) and other affected OS versions (iOS 16, watchOS 9, tvOS 16) as soon as possible. 2. Restrict installation of applications to trusted sources only, such as the Apple App Store or enterprise-signed apps, to reduce the risk of malicious apps exploiting this vulnerability. 3. Employ endpoint protection solutions that monitor for unauthorized file system modifications, especially in protected directories. 4. Implement strict user privilege management and educate users about the risks of interacting with untrusted applications or links that could trigger exploitation. 5. Use Mobile Device Management (MDM) tools to enforce security policies and ensure compliance with patching and application controls. 6. Monitor logs and system integrity checks for unusual changes in protected file system areas to detect potential exploitation attempts early. 7. For high-security environments, consider application whitelisting and sandboxing to limit app capabilities further.
