CVE-2025-24270 is a medium-severity vulnerability affecting Apple tvOS and other Apple operating systems including macOS Sequoia 15.4, tvOS 18.4, macOS Ventura 13.7.5, iPadOS 17.7.6, macOS Sonoma 14.7.5, iOS 18.4, iPadOS 18.4, and visionOS 2.4. The vulnerability arises from a flaw that allows an attacker on the local network to leak sensitive user information. Specifically, this vulnerability is categorized under CWE-200, which involves the exposure of sensitive information to unauthorized actors. The issue was resolved by removing the vulnerable code in the listed patched versions. The CVSS v3.1 base score is 5.7, indicating a medium severity level. The vector string (CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) reveals that the attack requires local network access (AV:A), has low attack complexity (AC:L), requires no privileges (PR:N), but does require user interaction (UI:R). The scope remains unchanged (S:U), and the impact is high on confidentiality (C:H) but no impact on integrity (I:N) or availability (A:N). This means that an attacker can potentially intercept or access sensitive user data without altering or disrupting system operations. No known exploits are currently reported in the wild. The vulnerability affects devices running vulnerable versions of Apple tvOS and related Apple OSes, which are commonly used in consumer and enterprise environments for media streaming and smart home integration. The attack vector being local network access implies that the attacker must be on the same network segment as the victim device, which could be a home or corporate Wi-Fi network. The requirement for user interaction suggests that some form of user action, such as clicking a link or opening a malicious app, is necessary to trigger the information leak. Overall, this vulnerability poses a risk of sensitive data exposure to attackers with local network access and some user engagement, but does not allow for system compromise or denial of service.

For European organizations, the impact of CVE-2025-24270 primarily concerns the confidentiality of sensitive user information on Apple tvOS devices and other affected Apple platforms. Many European enterprises and consumers use Apple devices for media consumption, communications, and smart home control, making these devices potential targets. In corporate environments where Apple TV devices are deployed for presentations or digital signage, sensitive corporate information could be exposed if an attacker gains local network access. The vulnerability could also be exploited in shared or public networks, such as hotels, airports, or conference centers, where attackers might attempt to harvest user data from connected Apple devices. Although the vulnerability does not affect system integrity or availability, the leakage of sensitive information could lead to privacy violations, corporate espionage, or further social engineering attacks. The requirement for user interaction reduces the likelihood of automated exploitation but does not eliminate risk, especially in environments where users may be less security-aware. Given the increasing use of Apple devices in European households and businesses, this vulnerability could have a moderate impact on privacy and data protection compliance, particularly under regulations like GDPR, if sensitive personal data is exposed.

1. Immediate patching: Organizations and users should promptly update all affected Apple devices to the fixed versions listed (e.g., tvOS 18.4, macOS Sequoia 15.4, iOS 18.4, etc.) to eliminate the vulnerable code. 2. Network segmentation: Restrict local network access to Apple tvOS devices by segmenting IoT and media devices on separate VLANs or subnets with strict access controls, minimizing exposure to potentially malicious local actors. 3. User awareness training: Educate users about the risks of interacting with unknown or suspicious content on their Apple devices, emphasizing caution with unsolicited links or apps that could trigger the vulnerability. 4. Monitor local network traffic: Deploy network monitoring tools to detect unusual local network scanning or suspicious traffic patterns targeting Apple devices, enabling early detection of potential exploitation attempts. 5. Limit guest network access: Configure guest Wi-Fi networks to isolate clients from each other and from corporate or private Apple devices, reducing the risk of local network attacks. 6. Device inventory and management: Maintain an up-to-date inventory of Apple devices and ensure centralized management to enforce timely updates and security policies. 7. Incident response readiness: Prepare to investigate and respond to potential data leakage incidents involving Apple tvOS devices, including forensic analysis of network logs and device states.
