CVE-2024-23285

This issue was addressed with improved handling of symlinks. This issue is fixed in macOS Sonoma 14.4. An app may be able to create symlinks to protected regions of the disk.

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.
