CVE-2024-44191 is a vulnerability identified in Apple’s Xcode development environment and related Apple operating systems that allows an application to gain unauthorized access to Bluetooth capabilities. The root cause is improper state management within the Bluetooth access control mechanisms, which can be exploited by an app with limited privileges to escalate its access rights to Bluetooth hardware. This flaw affects a broad range of Apple platforms including iOS (versions before 17.7), iPadOS (before 17.7), macOS Sequoia (before 15), tvOS (before 18), visionOS (before 2), and watchOS (before 11). The vulnerability does not require user interaction but does require local privileges, meaning an attacker must have the ability to install or run an app on the device. The CVSS v3.1 score is 5.5 (medium), reflecting that while the attack vector is local, the impact on integrity is significant as unauthorized Bluetooth access could enable malicious activities such as device tracking, data interception, or unauthorized device pairing. Apple has addressed this issue through improved state management in the affected software versions, and users are advised to update to these patched releases. No public exploits or active exploitation campaigns have been reported to date, but the vulnerability poses a risk especially in environments where app vetting is less stringent or devices are exposed to potentially malicious apps.

The primary impact of CVE-2024-44191 is the unauthorized escalation of Bluetooth access privileges by an app, which compromises the integrity of Bluetooth access controls. This could allow malicious apps to interact with Bluetooth devices without proper authorization, potentially leading to unauthorized data exchange, device tracking, or manipulation of Bluetooth-enabled peripherals. For organizations, this could result in breaches of sensitive data transmitted over Bluetooth, unauthorized access to corporate Bluetooth devices, or disruption of Bluetooth-dependent workflows. Although the vulnerability does not directly affect confidentiality or availability, the integrity compromise could facilitate further attacks or data leakage. The requirement for local privileges limits remote exploitation, but in environments with lax app controls or insider threats, the risk is elevated. The broad range of affected Apple platforms means that organizations relying on Apple ecosystems for development or deployment are at risk until patches are applied.

To mitigate CVE-2024-44191, organizations and users should promptly update to the fixed versions of Apple software: Xcode 16, iOS 17.7 and later, iPadOS 17.7 and later, macOS Sequoia 15 and later, tvOS 18 and later, visionOS 2 and later, and watchOS 11 and later. Developers should ensure that apps are built and tested using the updated Xcode to avoid introducing vulnerabilities related to Bluetooth access. Organizations should enforce strict app installation policies, limiting installation to trusted sources and employing mobile device management (MDM) solutions to control app deployment. Regular audits of Bluetooth permissions granted to apps can help detect unauthorized access attempts. Additionally, monitoring device logs for unusual Bluetooth activity may provide early warning of exploitation attempts. Since exploitation requires local privileges, controlling physical and logical access to devices is critical. Finally, educating users about the risks of installing untrusted apps can reduce the likelihood of exploitation.
