Apple Mac OS X vulnerable to privilege escalation when using Directory Services

Vulnerability Note VU#174790

Original Release Date: 2004-06-21 | Last Revised: 2004-07-21

Overview

A vulnerability in Mac OS X may permit a local authenticated user with physical access to the machine to gain elevated privileges.

Description

Mac OS X permits the remote authentication of users via directory sevices lookups. When a user logs in to a machine configured to use the Directory Services to provide authentication, it is possible to disconnect the machine's network connection and potentially be logged in with a Finder running as root. This gives the user full root permissions on the machine. Applications started in the session will also run as root.

This vulnerability affects Mac OS X 10.3 through 10.3.3.

Impact

A local authenticated user with physical access to the machine may be able to gain root privileges to the system.

Solution

Apple has resolved this issue in Mac OS X 10.3.4. A free upgrade is available at http://www.apple.com/support/downloads/.
