This issue was addressed with improved handling of symlinks. This issue is fixed in macOS Sonoma 14.1, macOS Monterey 12.7.1, macOS Ventura 13.6.1. A website may be able to access sensitive user data when resolving symlinks.
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 |
|---|---|---|---|
| Macos | Apple | 12.0.0 (including) | 12.7.1 (excluding) |
| Macos | Apple | 13.0 (including) | 13.6.1 (excluding) |
| Macos | Apple | 14.0 (including) | 14.1 (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.
