PhpWiki: Arbitrary command execution through XML-RPC — GLSA 200508-18

PhpWiki includes PHP XML-RPC code which is vulnerable to arbitrary command execution.

Affected packages

Package	www-apps/phpwiki on all architectures
Affected versions	< 1.3.10-r2
Unaffected versions	>= 1.3.10-r2

Background

PhpWiki is an application that creates a web site where anyone can edit the pages through HTML forms.

Description

Earlier versions of PhpWiki contain an XML-RPC library that 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 PhpWiki.

Workaround

There is no known workaround at this time.

Resolution

All PhpWiki users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-apps/phpwiki-1.3.10-r2"
