CVE-2025-24283 is a vulnerability identified in Apple’s iOS, iPadOS, visionOS, and macOS Sequoia operating systems, related to a logging mechanism that failed to properly redact sensitive user data. This flaw allows an application, potentially without elevated privileges, to access sensitive information that should be protected, due to improper sanitization of logs. The vulnerability is categorized under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The CVSS 3.1 score is 5.5 (medium), with an attack vector classified as local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:R). The scope is unchanged (S:U), and the impact is high on confidentiality (C:H), with no impact on integrity or availability. Apple fixed this issue in versions iOS 18.4, iPadOS 18.4, visionOS 2.4, and macOS Sequoia 15.4 by enhancing data redaction in the logging process, preventing sensitive data exposure. No public exploits have been reported, indicating the threat is currently theoretical but potentially exploitable by malicious apps installed on devices. The vulnerability could lead to unauthorized disclosure of personal or corporate sensitive data, which could be leveraged for further attacks or privacy violations.

For European organizations, the primary impact of CVE-2025-24283 is the potential unauthorized disclosure of sensitive user data on Apple devices. This could include personal information, credentials, or corporate data logged by the system. Such data leakage can lead to privacy breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and potential targeted attacks using the exposed information. Since the vulnerability requires local access and user interaction, the risk is higher in environments where users install untrusted apps or are susceptible to social engineering. Organizations with mobile workforces relying on Apple devices for sensitive communications or data processing are particularly at risk. The confidentiality breach could facilitate espionage, identity theft, or lateral movement within corporate networks. However, the lack of impact on integrity and availability limits the threat to data exposure rather than system disruption. The medium severity reflects these factors, but the widespread use of Apple devices in Europe elevates the importance of addressing this vulnerability promptly.

1. Deploy the latest Apple OS updates immediately: Ensure all iOS, iPadOS, visionOS, and macOS Sequoia devices are updated to versions 18.4, 2.4, and 15.4 respectively, where the vulnerability is patched. 2. Enforce strict app installation policies: Limit app installations to trusted sources such as the Apple App Store and use Mobile Device Management (MDM) solutions to control app permissions and installations. 3. Educate users on phishing and social engineering risks to reduce the likelihood of malicious app installation requiring user interaction. 4. Monitor device logs and network traffic for unusual access patterns or data exfiltration attempts that could indicate exploitation attempts. 5. Implement endpoint protection solutions capable of detecting anomalous app behavior on Apple devices. 6. Review and minimize logging of sensitive data where possible to reduce exposure risk. 7. For organizations with BYOD policies, enforce compliance checks to ensure devices are updated and secure. 8. Conduct regular security audits and penetration tests focusing on mobile device security to identify residual risks.
