PEAR XML-RPC, phpxmlrpc: New PHP script injection vulnerability — GLSA 200508-13

The PEAR XML-RPC and phpxmlrpc libraries allow remote attackers to execute arbitrary PHP script commands.

Affected Packages

dev-php/PEAR-XML_RPC on all architectures
Affected versions < 1.4.0
Unaffected versions >= 1.4.0
dev-php/phpxmlrpc on all architectures
Affected versions < 1.2-r1
Unaffected versions >= 1.2-r1

Background

The PEAR XML-RPC and phpxmlrpc libraries are both PHP implementations of the XML-RPC protocol.

Description

Stefan Esser of the Hardened-PHP Project discovered that the PEAR XML-RPC and phpxmlrpc libraries were improperly handling XMLRPC 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 web applications making use of these libraries.

Workaround

There are no known workarounds at this time.

Resolution

All PEAR-XML_RPC users should upgrade to the latest available version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-php/PEAR-XML_RPC-1.4.0"

All phpxmlrpc users should upgrade to the latest available version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-php/phpxmlrpc-1.2-r1"
