Synopsis

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

2. Impact Information

Background

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

Description

James Bercegay of GulfTech Security Research discovered that the PEAR XML-RPC and phpxmlrpc libraries fail to sanatize input sent using the "POST" method.

Impact

A remote attacker could exploit this vulnerability to execute arbitrary PHP script code by sending a specially crafted XML document to web applications making use of these libraries.

3. Resolution Information

Workaround

There are no known workarounds at this time.

Resolution

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

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-php/PEAR-XML_RPC-1.3.1"

All phpxmlrpc users should upgrade to the latest available version:
