CVE-2024-23280 is a vulnerability identified in Apple tvOS and related Apple platforms, including Safari browser versions prior to 17.4. The root cause is an injection issue that allows a maliciously crafted webpage to perform user fingerprinting. Fingerprinting is a technique used to collect unique device and user information to track users across sessions and websites without relying on traditional cookies. This vulnerability arises from insufficient input validation in the browser engine, which was improved in the patched versions. The CVSS 3.1 base score of 7.5 reflects a high severity due to the network attack vector, no privileges required, but user interaction needed (visiting a malicious webpage). The impact covers confidentiality, integrity, and availability, indicating that the vulnerability could be exploited to gather sensitive user data, manipulate browser behavior, or cause denial of service conditions. The vulnerability affects multiple Apple platforms, including tvOS, macOS, iOS, iPadOS, and watchOS, but this analysis focuses on tvOS. No known exploits have been reported in the wild yet, but the potential for privacy invasion and tracking is significant. The fix was released in Safari 17.4 and corresponding OS updates (tvOS 17.4, macOS Sonoma 14.4, iOS 17.4, iPadOS 17.4, watchOS 10.4), which implement improved validation to prevent injection attacks. Organizations relying on Apple TV devices for media delivery or internal applications should apply these updates promptly to mitigate risk.

For European organizations, this vulnerability poses a substantial privacy and security risk. User fingerprinting can lead to unauthorized tracking and profiling of users, potentially violating GDPR and other privacy regulations. Confidentiality is impacted as attackers may collect sensitive device and user information. Integrity and availability impacts suggest that exploitation could also disrupt device operation or manipulate content delivery. Sectors such as media streaming, hospitality, education, and corporate environments using Apple TV devices for presentations or digital signage are particularly vulnerable. The ability to fingerprint users can facilitate targeted attacks, social engineering, or unauthorized data collection, undermining trust and compliance. Additionally, organizations may face reputational damage and legal consequences if user privacy is compromised. Given the widespread use of Apple devices in Europe, the threat is relevant across multiple industries and use cases.

1. Immediately deploy the security updates: tvOS 17.4 and Safari 17.4 or later, along with corresponding updates for other Apple platforms. 2. Restrict access to untrusted or unknown web content on Apple TV devices by configuring network controls or using content filtering solutions. 3. Implement network monitoring to detect unusual traffic patterns or connections originating from Apple TV devices that might indicate exploitation attempts. 4. Educate users and administrators about the risks of visiting untrusted websites on Apple TV and other Apple devices. 5. Where possible, disable or limit Safari usage on Apple TV devices in sensitive environments. 6. Review and update privacy policies and compliance measures to address risks associated with fingerprinting and tracking. 7. Consider deploying endpoint detection and response (EDR) solutions that support Apple platforms to detect anomalous behavior. 8. Maintain an inventory of Apple TV devices and ensure they are included in patch management processes.
