GLSA 200606-16: DokuWiki: PHP code injection

http://security.gentoo.org/

Severity:	high
Title:	DokuWiki: PHP code injection
Date:	06/14/2006
Bugs:	#135623
ID:	200606-16

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	Architecture(s)
www-apps/dokuwiki	< 20060309-r1	>= 20060309-r1	All supported architectures

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"
