Vulnerability Note VU#474969

Original Release Date: 2007-04-20 | Last Revised: 2007-04-20


A vulnerability in the way that Apple Macintosh OS X mounts WebDAV filesystems could allow a local attacker to execute commands with elevated privileges.


Web-based Distributed Authoring and Versioning (WebDAV) is a set of extensions to the HTTP protocol which allows collaborative editing and management of web resources on remote servers. Apple Macintosh OS X contains a vulnerability that could be exploited when it attempts to mount WebDAV filesystems that may allow a local attacker to execute commands with elevated privileges. According to Apple Security Update 2007-004:

When mounting a WebDAV filesystem, the load_webdav program may be launched without properly cleaning the environment. This may allow a local user to create files or execute commands with system privileges. This update addresses the issue by cleaning the environment prior to executing commands.


A local attacker may be able to execute commands with elevated privileges.
