VERIFY ADVISORY:
http://secunia.com/advisories/39235/
DESCRIPTION:
Kingcope has discovered a vulnerability in Sun Java System Web
Server, which can be exploited by malicious users to disclose
sensitive information.
The vulnerability is caused due to an error in the WebDAV
implementation when processing LOCK requests. This can be exploited
to disclose the content of arbitrary local files by sending a LOCK
command defining external XML entities.
Successful exploitation requires WebDAV write access.
The vulnerability is confirmed in version 7.0U8 for Windows. Other
versions may also be affected.
SOLUTION:
Restrict WebDAV access to trusted users only.
