CVE-2024-23246 is a vulnerability identified in Apple visionOS and several other Apple operating systems, including macOS Sonoma 14.4, iOS 17.4, iPadOS 17.4, watchOS 10.4, and tvOS 17.4. The flaw allows a malicious application to escape the sandbox environment, which is designed to isolate apps and limit their access to system resources and user data. This sandbox escape could enable an attacker to execute arbitrary code with elevated privileges, potentially accessing sensitive information or modifying system integrity. The vulnerability is classified under CWE-20, indicating improper input validation or handling that leads to the sandbox bypass. The CVSS v3.1 score of 8.1 reflects a high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), but the impact on confidentiality and integrity is high (C:H, I:H), with no impact on availability (A:N). Apple has remediated this issue by removing the vulnerable code in the specified OS versions. No public exploits have been reported yet, but the potential for exploitation exists given the severity and the widespread use of Apple devices. The vulnerability affects multiple platforms, increasing the attack surface for adversaries targeting Apple ecosystems, especially with the introduction of visionOS, Apple's new spatial computing platform. Organizations relying on Apple devices should be aware of this risk and apply patches promptly to prevent potential sandbox escapes that could lead to data breaches or system compromise.

For European organizations, the impact of CVE-2024-23246 could be significant, particularly for those heavily invested in Apple ecosystems, including visionOS devices and the latest macOS, iOS, and iPadOS versions. A successful sandbox escape could allow attackers to bypass app isolation, leading to unauthorized access to sensitive corporate data, intellectual property, or user credentials. This could result in data breaches, loss of confidentiality, and potential integrity violations of critical systems. The vulnerability could also facilitate further lateral movement within networks if attackers gain elevated privileges. Sectors such as finance, healthcare, government, and technology, which often use Apple devices for secure communications and operations, may face increased risks. Additionally, organizations adopting visionOS for augmented or mixed reality applications could be exposed to novel attack vectors. The requirement for user interaction means phishing or social engineering could be used to trigger exploitation, increasing the risk in environments with less stringent user awareness training. Although no known exploits are currently in the wild, the high CVSS score and broad platform impact necessitate urgent attention to prevent potential exploitation.

European organizations should implement the following specific mitigation steps: 1) Immediately update all Apple devices to the patched OS versions: macOS Sonoma 14.4, visionOS 1.1, iOS 17.4, iPadOS 17.4, watchOS 10.4, and tvOS 17.4 or later. 2) Enforce strict app installation policies, limiting installations to trusted sources such as the Apple App Store and using Mobile Device Management (MDM) solutions to control app permissions. 3) Enhance user training to recognize and avoid social engineering attempts that could trigger the vulnerability via malicious apps. 4) Monitor device and network logs for unusual activity indicative of sandbox escape attempts or privilege escalations. 5) Employ endpoint detection and response (EDR) tools tailored for Apple platforms to detect anomalous behaviors. 6) For organizations deploying visionOS, conduct thorough security assessments of spatial computing applications and restrict access to sensitive data within these environments. 7) Maintain an inventory of Apple devices and ensure timely patch management processes are in place. 8) Collaborate with Apple support and security advisories to stay informed about any emerging exploit techniques or additional patches.
