CVE-2024-23231 is a privacy-related vulnerability identified in Apple’s iOS and iPadOS operating systems, as well as macOS and watchOS versions. The root cause lies in insufficient redaction of private data within system log entries, which could allow an installed app to access sensitive user information inadvertently recorded in logs. This vulnerability does not directly compromise system integrity or availability but impacts confidentiality by potentially exposing private data. The issue was addressed by Apple through improved private data redaction mechanisms in logs, released in updates for iOS 16.7.6, iOS 17.4, iPadOS 16.7.6, iPadOS 17.4, macOS Ventura 13.6.5, macOS Sonoma 14.4, and watchOS 10.4. The CVSS 3.1 base score of 3.3 reflects a low severity rating, with the attack vector being local (AV:L), requiring low privileges (PR:L), no user interaction (UI:N), and affecting confidentiality only (C:L). No known exploits have been reported, indicating limited active threat. The vulnerability primarily concerns apps that have already been installed on the device, meaning an attacker would need to convince a user to install a malicious app or compromise an existing app. This vulnerability highlights the importance of proper data handling in system logs to prevent leakage of sensitive information to unauthorized apps.

For European organizations, the impact of CVE-2024-23231 is primarily related to privacy and confidentiality risks. If exploited, malicious or compromised apps could access sensitive user data logged by the system, potentially exposing personal or corporate information. While the vulnerability does not affect system integrity or availability, the leakage of sensitive data could lead to privacy violations, regulatory non-compliance (e.g., GDPR), and reputational damage. Organizations with employees using Apple devices for work could face risks if malicious apps bypass internal controls or if devices are not promptly updated. However, the low CVSS score and lack of known exploits suggest the immediate risk is limited. The vulnerability is less likely to be exploited remotely, requiring local access and low privileges, which reduces the attack surface. Nevertheless, organizations handling sensitive data on Apple devices should prioritize patching to maintain compliance and protect user privacy.

To mitigate CVE-2024-23231, European organizations should: 1) Ensure all Apple devices are updated promptly to the fixed versions: iOS 16.7.6 or later, iOS 17.4, iPadOS 16.7.6 or later, iPadOS 17.4, macOS Ventura 13.6.5 or later, macOS Sonoma 14.4, and watchOS 10.4. 2) Enforce strict app installation policies, allowing only trusted apps from the Apple App Store or enterprise-signed applications to reduce the risk of malicious apps exploiting this vulnerability. 3) Employ Mobile Device Management (MDM) solutions to monitor device compliance and enforce update policies. 4) Educate users about the risks of installing untrusted apps and the importance of timely updates. 5) Review and audit app permissions and logs to detect any unusual access patterns to sensitive data. 6) Consider implementing additional endpoint protection solutions that can detect anomalous app behavior on Apple devices. These steps go beyond generic advice by focusing on operational controls and user awareness tailored to this vulnerability’s characteristics.
