CVE-2022-42788 is a medium-severity vulnerability affecting Apple macOS systems, specifically addressed in macOS Ventura 13. The vulnerability arises from a permissions issue that allowed a malicious application to bypass intended access controls and read sensitive location information without proper authorization. The root cause is improper permission validation (CWE-863), which means that the system failed to correctly enforce access restrictions on location data. Exploitation requires local access (AV:L) and user interaction (UI:R), but no privileges are required (PR:N). The vulnerability impacts confidentiality by exposing sensitive location data, but does not affect integrity or availability. The CVSS 3.1 base score is 5.5, reflecting a medium severity level. There are no known exploits in the wild at this time, and Apple has addressed the issue by improving permission validation in macOS Ventura 13. The affected versions are unspecified but presumably include versions prior to Ventura 13. This vulnerability highlights the risk of sensitive data leakage through insufficient permission checks in operating system components handling location services.

For European organizations, the exposure of sensitive location information can have significant privacy and security implications. Location data can reveal user movements, patterns, and potentially confidential operational details, especially for organizations handling sensitive or regulated information. This could lead to privacy violations under GDPR if personal location data is accessed without consent. Additionally, adversaries could use location data to facilitate targeted attacks, physical surveillance, or social engineering. While the vulnerability does not allow system compromise or data integrity manipulation, the confidentiality breach alone is critical for sectors such as government, defense, finance, and critical infrastructure operators in Europe. Organizations relying on macOS devices should be aware that malicious applications, possibly delivered via phishing or social engineering, could exploit this vulnerability if users interact with them. The lack of known exploits reduces immediate risk but does not eliminate it, especially as threat actors may develop exploits over time.

European organizations should prioritize updating all macOS devices to Ventura 13 or later, where the vulnerability is fixed. Until updates are applied, organizations should enforce strict application control policies to prevent installation or execution of untrusted or unsigned applications that could exploit this vulnerability. Endpoint protection solutions with behavioral detection should be tuned to monitor for suspicious access to location services. User training is critical to reduce the risk of social engineering attacks that could trick users into running malicious apps. Additionally, organizations should audit and restrict location services permissions on macOS devices, granting access only to trusted applications. Network segmentation and monitoring can help detect lateral movement attempts if location data is used to facilitate further attacks. Finally, organizations should review their privacy policies and ensure compliance with GDPR regarding location data handling and breach notification procedures.
