CVE-2024-44273

This issue was addressed with improved handling of symlinks. This issue is fixed in iOS 18.1 and iPadOS 18.1, visionOS 2.1, macOS Sonoma 14.7.1, watchOS 11.1, tvOS 18.1. A malicious app may be able to access private information.

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Potential Mitigations

• Follow the principle of least privilege when assigning access rights to entities in a software system.
• Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
