Synopsis
========
Vulnerabilities in some accessory scripts of DokuWiki allow remote code
execution.
Background
==========
DokuWiki is a wiki targeted at developer teams, workgroups and small
companies. It does not use a database backend.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/dokuwiki < 20060309d >= 20060309d
Description
===========
"rgod" discovered that DokuWiki doesn't sanitize the X-FORWARDED-FOR
HTTP header, allowing the injection of arbitrary contents - such as PHP
commands - into a file. Additionally, the accessory scripts installed
in the "bin" DokuWiki directory are vulnerable to directory traversal
attacks, allowing to copy and execute the previously injected code.
Impact
======
A remote attacker may execute arbitrary PHP (and thus probably system)
commands with the permissions of the user running the process serving
DokuWiki pages.
Workaround
==========
Disable remote access to the "bin" subdirectory of the DokuWiki
installation. Remove the directory if you don't use the scripts in
there.
Resolution
==========
All DokuWiki users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/dokuwiki-20060309d"
