CVE-2025-30447 is a vulnerability identified in Apple tvOS and other Apple operating systems including visionOS, macOS Ventura, macOS Sequoia, macOS Sonoma, iOS, and iPadOS. The core issue stems from insufficient sanitization of logging mechanisms within the OS, which could allow a malicious app to access sensitive user data that should otherwise be protected. This vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The flaw does not require elevated privileges (PR:N), but does require user interaction (UI:R) and local access (AV:L), meaning an attacker must convince a user to run a malicious app on the device. The CVSS v3.1 base score is 5.5, indicating medium severity, with a high impact on confidentiality (C:H), but no impact on integrity (I:N) or availability (A:N). The vulnerability was addressed by Apple through sanitizing logging inputs to prevent leakage of sensitive data. The fix is included in tvOS 18.4 and corresponding updates for other Apple OS versions released around the same time. No known exploits have been reported in the wild, suggesting limited active exploitation. However, the vulnerability poses a risk especially in environments where Apple TV devices or other affected Apple platforms are used for sensitive operations. Attackers could leverage this flaw to extract sensitive information from logs that were not properly sanitized, potentially leading to privacy breaches or leakage of confidential data. The vulnerability affects all versions prior to the patched releases, but the exact affected versions are unspecified. Given the requirement for user interaction and local access, the threat is somewhat mitigated by user awareness and app installation controls.

For European organizations, the primary impact of CVE-2025-30447 is the potential exposure of sensitive user data on Apple devices, particularly Apple TV units used in corporate or home office environments. Confidentiality breaches could lead to leakage of personal or corporate information, undermining privacy and compliance with regulations such as GDPR. Although the vulnerability does not affect system integrity or availability, unauthorized data access can facilitate further attacks or espionage. Organizations relying on Apple ecosystems for media delivery, conferencing, or digital signage may face risks if malicious apps are installed. The requirement for user interaction and local access reduces the likelihood of remote exploitation but does not eliminate insider threats or social engineering risks. The absence of known exploits in the wild currently limits immediate impact, but unpatched devices remain vulnerable. Failure to patch could result in reputational damage, regulatory penalties, and loss of trust if sensitive data is compromised. The broad range of affected Apple OS versions means organizations with mixed Apple device environments must ensure comprehensive patch management to mitigate risks.

To mitigate CVE-2025-30447, European organizations should: 1) Immediately deploy the latest Apple OS updates including tvOS 18.4, visionOS 2.4, macOS Ventura 13.7.5, macOS Sequoia 15.4, macOS Sonoma 14.7.5, iOS 18.4, and iPadOS 17.7.6 or later on all affected devices. 2) Restrict installation of apps on Apple TV and other Apple devices to trusted sources such as the official Apple App Store, and implement Mobile Device Management (MDM) policies to control app deployment. 3) Educate users about the risks of installing untrusted applications and the importance of verifying app legitimacy to reduce social engineering risks. 4) Monitor device logs and network traffic for unusual activity that could indicate attempts to exploit logging mechanisms or data exfiltration. 5) Employ endpoint security solutions capable of detecting anomalous app behavior on Apple devices. 6) Regularly audit Apple device inventories to identify and remediate unpatched or unauthorized devices. 7) Consider network segmentation for Apple TV devices used in sensitive environments to limit lateral movement in case of compromise. 8) Maintain up-to-date incident response plans that include scenarios involving Apple device vulnerabilities and data leakage.
