This issue was addressed with improved validation of symlinks. This issue is fixed in iOS 18 and iPadOS 18, macOS Sequoia 15. An app may be able to access sensitive user data.

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

Name Vendor Start Version End Version
Ipados Apple * 18.0 (excluding)
Iphone_os Apple * 18.0 (excluding)
Macos Apple * 15.0 (excluding)

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.
