This issue was addressed with improved validation of symlinks. This issue is fixed in macOS Ventura 13.7.5, macOS Sequoia 15.4, macOS Sonoma 14.7.5. A path handling issue was addressed with improved validation.

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.

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.
