CVE-2024-23290 is a logic vulnerability identified in Apple tvOS and related Apple operating systems including iOS 17.4, iPadOS 17.4, macOS Sonoma 14.4, and watchOS 10.4. The flaw stems from insufficient restrictions in the system's logic that could allow an application with limited privileges (low privilege level) to access user-sensitive data improperly. The vulnerability does not require user interaction to be exploited, but the attacker must have local access and low privileges on the device. The weakness is categorized under CWE-922, which relates to improper restriction of operations within the bounds of a memory buffer or logical access control. The vulnerability impacts confidentiality, integrity, and availability to a limited degree, as indicated by the CVSS vector (AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) and a CVSS score of 5.3 (medium severity). Apple addressed this issue by improving restrictions in the affected operating systems, releasing patches in version 17.4 for tvOS, iOS, iPadOS, macOS Sonoma 14.4, and watchOS 10.4. There are no known exploits in the wild at this time, but the potential for sensitive data exposure makes timely patching important. The vulnerability affects a broad range of Apple devices, including Apple TV, iPhones, iPads, Macs, and Apple Watches, which are widely used in both consumer and enterprise environments.

For European organizations, this vulnerability poses a moderate risk primarily to confidentiality due to potential unauthorized access to sensitive user data by malicious or compromised applications. The integrity and availability impacts are limited but present. Organizations using Apple devices in corporate environments, particularly those deploying Apple TV for conferencing, digital signage, or media distribution, could face data leakage risks. The vulnerability could be exploited by insiders or malware that gains low-level access to devices, potentially leading to exposure of sensitive information such as credentials, personal data, or corporate secrets. Given the widespread use of Apple devices in Europe, especially in sectors like finance, technology, and media, the risk of data breaches or privacy violations is non-negligible. However, the requirement for local access and low privileges reduces the likelihood of remote exploitation. The absence of known exploits in the wild currently lowers immediate risk but does not eliminate the need for proactive mitigation.

European organizations should prioritize updating all affected Apple devices to the patched versions: tvOS 17.4, iOS 17.4, iPadOS 17.4, macOS Sonoma 14.4, and watchOS 10.4. Beyond patching, organizations should enforce strict application installation policies, limiting apps to those from trusted sources and employing Mobile Device Management (MDM) solutions to control app permissions and monitor device integrity. Implementing endpoint security solutions that detect anomalous app behavior can help identify attempts to exploit this vulnerability. Network segmentation and limiting physical access to Apple devices can reduce the risk of local exploitation. Regular audits of installed applications and user privileges on Apple devices will help identify and mitigate potential attack vectors. Educating users about the risks of installing unauthorized applications and maintaining strong access controls on devices will further reduce exposure.
