phpWebSite: Arbitrary command execution through XML-RPC and SQL injection

Background

phpWebSite is a web site content management system.

Description

phpWebSite uses an XML-RPC library that improperly handles XML-RPC requests and responses with malformed nested tags. Furthermore, “matrix_killer” reported that phpWebSite is vulnerable to an SQL injection attack.

Impact

A malicious remote user could exploit this vulnerability to inject arbitrary PHP script code into eval() statements by sending a specially crafted XML document, and also inject SQL commands to access the underlying database directly.

Workaround

There is no known workaround at this time.

Resolution

All phpWebSite users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-apps/phpwebsite-0.10.2_rc2"
