http://security.gentoo.org/

Severity:	high
Title:	PEAR XML-RPC, phpxmlrpc: PHP script injection vulnerability
Date:	07/03/2005
Bugs:	#97399, #97629
ID:	200507-01

Synopsis

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

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-php/PEAR-XML_RPC	< 1.3.1	>= 1.3.1	All supported architectures
dev-php/phpxmlrpc	< 1.1.1	>= 1.1.1	All supported architectures

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.

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-1.3.1"

All phpxmlrpc users should upgrade to the latest available version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-php/phpxmlrpc-1.1.1"
