Synopsis
========
A flaw in DokuWiki's spell checker allows for the execution of
arbitrary PHP commands, even without proper authentication.
Background
==========
DokuWiki is a simple to use wiki targeted at developer teams,
workgroups and small companies.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/dokuwiki < 20060309-r1 >= 20060309-r1
Description
===========
Stefan Esser discovered that the DokuWiki spell checker fails to
properly sanitize PHP's "complex curly syntax".
Impact
======
A unauthenticated remote attacker may execute arbitrary PHP commands -
and thus possibly arbitrary system commands - with the permissions of
the user running the webserver that serves DokuWiki pages.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All DokuWiki users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/dokuwiki-20060309-r1"
