PHP: Script injection through XML-RPC — GLSA 200507-15

PHP includes an XML-RPC implementation which allows remote attackers to execute arbitrary PHP script commands.

Affected Packages

dev-php/php on all architectures
Affected versions < 4.4.0
Unaffected versions >= 4.4.0

Background

PHP is a general-purpose scripting language widely used to develop web-based applications. It can run inside a web server using the mod_php module or the CGI version of PHP, or can run stand-alone in a CLI.

Description

James Bercegay has discovered that the XML-RPC implementation in PHP fails to sanitize input passed in an XML document, which is used in an "eval()" statement.

Impact

A remote attacker could exploit the XML-RPC vulnerability to execute arbitrary PHP script code by sending specially crafted XML data to applications making use of this XML-RPC implementation.

Workaround

There is no known workaround at this time.

Resolution

All PHP users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-php/php-4.4.0"
