Synopsis
========
An input sanitation error in DokuWiki might lead to the dislosure of
local files or even the remote execution of arbitrary code.
Background
==========
DokuWiki is a standards compliant Wiki system written in PHP.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/dokuwiki < 2009-02-14b >= 2009-02-14b
Description
===========
girex reported that data from the "config_cascade" parameter in
inc/init.php is not properly sanitized before being used.
Impact
======
A remote attacker could exploit this vulnerability to execute PHP code
from arbitrary local, or, when the used PHP version supports ftp://
URLs, also from remote files via FTP. Furthermore, it is possible to
disclose the contents of local files. NOTE: Successful exploitation
requires the PHP option "register_globals" to be enabled.
Workaround
==========
Disable "register_globals" in php.ini.
Resolution
==========
All DokuWiki users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =www-apps/dokuwiki-2009-02-14b
