Background

TikiWiki is a full featured Free Software Wiki, CMS and Groupware written in PHP. eGroupWare is a web-based collaboration software suite. Both TikiWiki and eGroupWare include a PHP library to handle XML-RPC requests.

Description

The XML-RPC library shipped in TikiWiki and eGroupWare improperly handles XML-RPC requests and responses with malformed nested tags.

Impact

A remote attacker could exploit this vulnerability to inject arbitrary PHP script code into eval() statements by sending a specially crafted XML document to TikiWiki or eGroupWare.

Workaround

There is no known workaround at this time.

Resolution

All TikiWiki users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-apps/tikiwiki-1.8.5-r2"
