Folder Manager in Apple Mac OS X 10.5.8, and 10.6 before 10.6.4, allows local users to delete arbitrary folders via a symlink attack in conjunction with an unmount operation on a crafted volume, related to the Cleanup At Startup folder.

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.
