Vulnerability Note VU#168020

Apple Mac OS X AFP server stores reconnect keys in a world-readable file

Original Release date: 04 Aug 2006 | Last revised: 04 Aug 2006

Overview

A vulnerability in Apple Mac OS X AFP server may allow an authenticated local user to access files or folders with the credentials of another user.

Description

The AFP (Apple Filing Protocol) service allows Apple Mac OS clients to remotely access files from a server. In Apple's Mac OS X Server, the AFP server supports automatic reconnection of file sharing after a network outage by storing reconnect keys locally. The storage of these reconnect keys is unprotected by appropriate file system permissions. As a result, it is possible for an authenticated local user to read the reconnect keys and use them to access files and folders on the server with the system credentials of another user.

Impact

A user may be able to view sensitive reconnect keys within an unprotected file and use those keys to gain access with the credentials of another user. Apple states that this issue only affects Apple Mac OS X Server.
