CVE-2022-32805 is a medium-severity vulnerability affecting Apple macOS operating systems, specifically versions prior to the Security Update 2022-005 Catalina, macOS Big Sur 11.6.8, and macOS Monterey 12.5. The vulnerability arises from improper handling of caches within the system, which could allow a malicious application to access sensitive user information without requiring privileges or authentication. The flaw is categorized under CWE-200, indicating an exposure of sensitive information. Exploitation requires local access (attack vector: local), and user interaction is necessary (UI:R), but no privileges are required (PR:N). The vulnerability impacts confidentiality (C:H) but does not affect integrity or availability. The issue was addressed by Apple through improved cache handling in the specified security updates. There are no known exploits in the wild at the time of publication, and the vulnerability does not require elevated privileges, making it potentially exploitable by any app running on the affected systems if the user interacts with it. This vulnerability highlights the risk of sensitive data leakage through system-level cache mishandling, which could lead to privacy breaches or unauthorized data disclosure on affected macOS devices.

For European organizations, this vulnerability poses a risk primarily to confidentiality of sensitive user information on macOS devices. Organizations with employees or systems running vulnerable macOS versions could face unauthorized data exposure if malicious applications are executed locally. This could lead to leakage of personal or corporate information, potentially violating data protection regulations such as GDPR. Although exploitation requires user interaction and local access, the widespread use of macOS in sectors like creative industries, finance, and technology in Europe means that sensitive data could be at risk. The absence of known exploits reduces immediate risk, but the medium severity and ease of exploitation without privileges suggest that targeted attacks or insider threats could leverage this vulnerability. Organizations relying on macOS for critical operations should consider this vulnerability in their risk assessments, especially where sensitive or regulated data is handled.

European organizations should ensure that all macOS devices are updated promptly to Security Update 2022-005 Catalina, macOS Big Sur 11.6.8, or macOS Monterey 12.5 or later. Beyond patching, organizations should implement strict application control policies to prevent installation or execution of untrusted or unsigned applications, reducing the risk of malicious apps exploiting this vulnerability. Employ endpoint detection and response (EDR) solutions capable of monitoring unusual local application behavior and data access patterns. User education is critical to minimize risky interactions with untrusted applications or files. Additionally, enforcing least privilege principles and restricting local user permissions can limit the impact of potential exploitation. Regular audits of installed software and system configurations can help identify vulnerable systems and unauthorized applications. Finally, integrating macOS devices into centralized security management platforms can facilitate timely patch deployment and vulnerability management.
