Release Date August 24, 2005
Latest Revision August 24, 2005: 01
Impact high
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
dev-php/PEAR-XML_RPC < 1.4.0 >= 1.4.0 All supported architectures
dev-php/phpxmlrpc < 1.2-r1 >= 1.2-r1 All supported architectures

Related bugreports: #102378, #102576


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

2.  Impact Information


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


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.


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.

3.  Resolution Information


There are no known workarounds at this time.


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-1.4.0"

All phpxmlrpc users should upgrade to the latest available version:

Code Listing 3.2: Resolution

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