CVE-2024-54514 is a vulnerability identified in Apple tvOS and other Apple operating systems that allows an application to break out of its sandbox. The sandbox is a security mechanism that restricts apps to a controlled environment, limiting their access to system resources and user data. This vulnerability arises from insufficient checks in the sandbox enforcement, permitting an app to escape these restrictions and potentially access or manipulate data outside its designated boundaries. The issue affects multiple Apple platforms, including tvOS, watchOS, iOS, iPadOS, and macOS, with patches released in watchOS 11.2, tvOS 18.2, macOS Sequoia 15.2, iOS 18.2, iPadOS 18.2, macOS Ventura 13.7.2, and macOS Sonoma 14.7.2. The CVSS v3.1 score is 8.2, indicating high severity, with an attack vector requiring local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), and high impact on confidentiality and integrity (C:H/I:H), but no impact on availability (A:N). Although no exploits have been reported in the wild, the vulnerability poses a significant risk because a malicious app could gain unauthorized access to sensitive information or escalate privileges, undermining system security. The vulnerability's exploitation requires the user to run a malicious app, which could be delivered through sideloading or less controlled app distribution channels. The improved checks implemented in the patches strengthen sandbox enforcement, preventing apps from escaping their restricted environment.

For European organizations, the impact of CVE-2024-54514 can be substantial, especially for those relying on Apple TV devices for digital signage, conferencing, or media distribution, as well as enterprises using Apple ecosystems extensively. A successful sandbox escape could lead to unauthorized access to sensitive corporate data, intellectual property, or user credentials stored or accessible via the device. It could also enable lateral movement within networks if the compromised device is connected to corporate infrastructure. The integrity of the system could be compromised, allowing malicious apps to alter configurations or inject malicious code. Although availability is not directly impacted, the breach of confidentiality and integrity could lead to reputational damage, regulatory penalties under GDPR, and operational disruptions. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, particularly in environments where devices are shared or less physically secure. Organizations with strict security policies and controlled app deployment will face lower risk, but those with more open app installation policies or BYOD environments may be more vulnerable.

1. Immediately update all affected Apple devices to the patched OS versions: tvOS 18.2, watchOS 11.2, iOS/iPadOS 18.2, and macOS versions 13.7.2, 14.7.2, and Sequoia 15.2. 2. Enforce strict app installation policies, limiting installations to the Apple App Store or enterprise-approved apps to reduce the risk of malicious apps. 3. Implement Mobile Device Management (MDM) solutions to monitor and control app deployments and device configurations. 4. Educate users about the risks of installing untrusted applications and the importance of applying updates promptly. 5. Restrict physical access to Apple TV and other Apple devices in sensitive environments to prevent local exploitation. 6. Monitor device logs and network traffic for unusual activity that could indicate sandbox escape attempts or lateral movement. 7. Consider network segmentation for Apple devices to limit potential impact if a device is compromised. 8. Regularly audit device compliance with security policies and patch levels to ensure ongoing protection.
