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

http://security.gentoo.org/

Severity:	high
Title:	PHP: Script injection through XML-RPC
Date:	07/15/2005
Bugs:	#97655
ID:	200507-15

Synopsis

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

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.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-php/php	< 4.4.0	>= 4.4.0	All supported architectures

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"
