[GLSA]

Gentoo Linux Security Advisory

Title: PHP: Script injection through XML-RPC (GLSA 200507-15)
Severity: high
Exploitable: remote
Date: July 15, 2005
Bug(s): #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: dev-php/php
Vulnerable: < 4.4.0
Unaffected: >= 4.4.0
Architectures: 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:
