CVE-2024-54525 is a logic vulnerability in Apple iOS and iPadOS related to the restoration of backup files. Specifically, when a user restores a backup file that has been maliciously crafted, the flawed file handling logic can allow the attacker to modify protected system files that should normally be inaccessible. This vulnerability is classified under CWE-434, which involves improper handling of file uploads or file inputs leading to security issues. The flaw permits an attacker to bypass normal file protection mechanisms during the restore process, potentially enabling them to alter system files that control device behavior, security policies, or system integrity. The vulnerability has a CVSS 3.1 base score of 8.8, indicating high severity, with attack vector being network-based, no privileges required, but user interaction is necessary (restoring the backup). The impact includes full compromise of confidentiality, integrity, and availability of the device. Apple has fixed this issue in iOS 18.2, iPadOS 18.2, macOS Sequoia 15.2, tvOS 18.2, visionOS 2.2, and watchOS 11.2. No public exploits are known at this time, but the potential for serious damage makes timely patching critical.

The vulnerability allows attackers to modify protected system files by tricking users into restoring a malicious backup, potentially leading to full device compromise. This can result in unauthorized access to sensitive data, persistent malware installation, disruption of device functionality, and bypass of security controls. For organizations, this could mean loss of confidential corporate information, unauthorized surveillance, or disruption of critical mobile workflows. The broad impact on confidentiality, integrity, and availability makes this a critical risk for any entity relying on Apple mobile devices for secure communications or operations. The requirement for user interaction limits remote exploitation but social engineering or targeted attacks could facilitate exploitation. The vulnerability also affects multiple Apple platforms, increasing the scope of potential impact across diverse device types.

Organizations and users should immediately update affected Apple devices to iOS 18.2, iPadOS 18.2, or later versions where the vulnerability is patched. Avoid restoring backups from untrusted or unknown sources. Implement strict policies on backup file handling and educate users about the risks of restoring backups from suspicious origins. Employ mobile device management (MDM) solutions to enforce OS version compliance and restrict unauthorized backup restoration. Monitor device behavior for signs of compromise post-restore, such as unexpected system file changes or abnormal device activity. For enterprises, consider restricting backup restoration capabilities to IT-managed processes only. Regularly audit device backups and restoration procedures to ensure integrity and security.
